Granitoid pluton formation by spreading of continental crust: the Wiley Glacier complex, northwest Palmer Land, Antarctica.

first_imgThe emplacement mechanism, geometry, and isotope geochemistry of plutons of the Wiley Glacier complex suggest that new continental crust grew by multiple injection of tonalitic dykes during dextral transtension in the Antarctic Peninsula magmatic are in Early Cretaceous times. The suggested mechanism is analogous to basalt dyke injection during sea-floor spreading. During normal-dextral shear, the Bums Bluff pluton, a sheeted, moderately east-dipping, syn-magmatically sheared tonalite- granodiorite intruded syn-magmatically sheared quartz diorite of the Creswick Gap pluton and 140 +/- 5 Ma homblende gabbro. U-Pb dating of zircon and Ar-Ar dating of hornblende and biotite suggest that both granite s.l. plutons were emplaced between 145 and 140 Ma, but that extensional shearing was active from the time of emplacement until ca. lu Ma. The Bums Bluff pluton is chilled at its margin, and grades through mylonitised, porphyritic tonalite-granodiorite sheets and tonalite-granodiorite sheets with minor chilling, to a kilometre-scale body of coarse-grained, hypidiomorphic tonalite-granodiorite Co-magmatic microdiorite forms dykes and abundant synplutonic mafic enclaves. These dykes opened as echelon veins during episodic dextral shear and were deformed to trains of enclaves during continued normal-dextral shear. Pluton-marginal porphyritic and hypidiomorphic tonalite- granodiorite forms large, fault-hosted sheets emplaced progressively under extension with minor dextral shear. Kinematic indicators from pluton-marginal granite s.l. dykes suggest that early in pluton accretion, intrusive sheets cooled rapidly, with simple shear prior to full crystallisation changing to ductile simple shear during cooling. Kinematic indicators towards the pluton core suggest that as the pluton grew, and cooled more slowly, emplacement switched from sheeting to in situ inflation with simple shear distributed across a broad zone prior to full crystallisation of magma. Cross-cutting relationships with the coeval, syn-extensional, Creswick Gap pluton suggest that the Bums Bluff pluton was emplaced in a steeper, second generation shear structure, like those in normal fault systems. This suggests that the Wiley Glacier complex was emplaced above the base of the brittle- ductile transition zone (15-18 km depth). The Bums Bluff pluton has Nd and Sr isotope values that range from mantle dominated (is an element of Nd-141 = +3.8, Sr-87/Sr-86(141) = 0.70468) to more crustally influenced (is an element of Nd-141 = -1.7, Sr- 87/Sr-86(141) = 0.70652) This range probably represents different degrees of mixing between mantle-derived magma and lower crustal partial melts generated in the garnet-stability zone (40+ km depth). Addition of new crustal material by mafic underplating at the base of the crust and by redistribution of granitic s.l. and mafic, modified, underplated magma to mid- crustal levels along extensional shear zones as the are ‘spread’ were the primary mechanisms of crustal growth.last_img read more

US Navy Reserve Celebrates 97th Year of Establishment

first_img View post tag: News by topic US Navy Reserve Celebrates 97th Year of Establishment View post tag: Reserve View post tag: establishment March 7, 2012 View post tag: US View post tag: celebrates U.S. Navy personnel attended a birthday celebration honoring the Navy Reserve’s 97th year of establishment at the Navy Memorial March 2.Chief of Navy Reserve (CNR) Vice Adm. Dirk J. Debbink, spoke during the celebration where he retold many key points in the Navy Reserve’s history.“Our Navy Reserve was established 97 years ago on March 3, 1915, and in those 97 years we have served the nation with distinction,” Debbink said. “Our nation is free today in part because of those Sailors who went before us and stood the watch with honor in both peace and war. We can take enormous pride in our Navy Reserve heritage.”CNR explained how the role of members of the Navy Reserve had changed throughout the years and how they continued to be there for the Navy and the nation.“Before now, mobilization was maybe a one-time, once in a career event,” Debbink said. “It’s been more than 10 years since 9/11. That means that every Sailor has enlisted or re-enlisted since this conflict began, knowing that mobilization is not a question of if, but when.”Navy Reserve Force Master Chief (AW) Chris Wheeler and Master Chief Petty Officer of the Navy (MCPON)(SS/SW) Rick D. West also spoke during the celebration.MCPON led the audience in singing “Happy Birthday” to the Navy Reserve then spoke to the audience about how Sailors embody the “Navy Ethos.”“The “Navy Ethos” is a document that really does identify who we are as an organization and clearly charts a course of character and integrity,” West said. “If you read the ethos carefully you will realize you have been living those words since joining the navy for the first time though the spirit of maritime service has been captured and put on paper.”During the celebration employers, DoD civilians, Navy ombudsman, and Reserve Sailors who embody the “Navy Ethos” were presented with awards.Acting Assistant Secretary of Defense for Reserve Affairs David L. McGinnis presented the Employer Support of the Guard and Reserve Seven Seals award to United States Department of Agriculture Office of Ethics for their support of Navy Reservists.Deputy Assistant Secretary of the Navy Infrastructure Strategy and Analysis Dennis Biddick presented homecoming statues in recognition of Linda Morton, Michelle Harvey and Sally Guild to recognize their superior support as Navy Operational Support Center Ombudsmen.“These volunteers have a direct line to the Commanding Officer to address matters of concern regarding families. They are so much more though,” Debbink said. “They are trained to help families avoid problems. They know how to get resources when there are problems. And often, they are the first and best friend a new family has coming to a unit.”Debbink also recognized the three ombudsmen with certificates of recognition to express appreciation for their unselfish, faithful, and dedicated service as Navy ombudsman for more than 4,500 Sailors and their families.As a new addition to being recognized during the Navy Reserve Anniversary Commander, Navy Reserve Forces Command (CNRFC) Junior and Senior Civilians of the Year, Sandra Buchanan and Dawn Moore.“Our civilian workforce is an essential component of our Navy Total Force – active, Reserve and civilians, all working together, with their own unique contributions to our effort,” Debbink said.Finally medals were presented to five Navy Reserve Sailors who embody the Ready Now spirit of the Navy Reserve.“Because of the people here today, and people like them all over the world, the Navy Reserve will always be Ready Now. Anytime, Anywhere,” Debbink said. “If the Navy Reserve is Ready Now, we can help ensure that our Navy – America’s Navy: A Global Force For Good – will be strong in the future.”[mappress]Naval Today Staff , March 07, 2012 View post tag: Naval View post tag: Navy View post tag: Year Back to overview,Home naval-today US Navy Reserve Celebrates 97th Year of Establishment Training & Education View post tag: 97th Share this articlelast_img read more

Merton to fight Council in £1 million High Court battle

first_imgMerton has launched a High Court legal challenge to Oxford City Council’s social housing charge. Under a new policy, permission for student accommodation will only be granted if a financial contribution is secured towards social housing elsewhere in Oxford. These rules apply to buildings of 20 or more bedrooms.Merton College is leading a group of several colleges, and student housing developer McLaren Property, in alleging that  the charge is a “an unauthorised housing tax”. According to UK law, councils can levy charges but not taxes on the construction of property.Merton planned to build accommodation for 298 students at Manor Place in central Oxford, but says the scheme is now unviable due to the charge. Merton cites an increase in cost of £140 per square metre, plus a five per cent administration charge, as reasons for halting building plans. The charge has been estimated to add £1m to the cost of the scheme.Oxford Brookes University also criticised the policy, saying that for the 313- bed Dorset House development on London Road, the council’s changes would have meant forcibly giving £1.37m towards affordable housing.A statement from Merton and McLaren said, “This legal process is now the only possible method of challenge available to us of a policy which will have the effect of making the development at Manor Place unviable. The impact of the policy does not solely affect Manor Place, but will have a wider implication across other potential development sites in the city.”Stuart Black, Development Manager of McLaren, said, “The plan would stop dead student accommodation in Oxford that is done on a commercial basis.”A City Council spokesman defended the policies, telling The Oxford Mail that, “We will continue to defend the adoption of these policies as fair and appropriate.”Colin Cook, a council board member specialising in city development, said he wanted to prioritise new homes over student accomodation. He claimed that the policy removes a loophole that allows developers to recieve permission for student flats that are later used as private homes.Although Oxford University is not participating in the legal challenge, a spokesperson stated, “Through developing student accommodation, the University and colleges alleviate the pressure on the private rental market in the city, and meet obligations laid down by the City Council. These things are of benefit to the local community. Yet under these changes, we will be penalised for doing so.“Oxford students benefit from greater provision of University and college owned accommodation than those at almost any other university. This offers protection from the private rental market, allowing undergraduates in particular to pay rent only in term time, making a cost saving.“Oxford students will continue to be well provided with accommodation, even under these changes.”A Merton student commented, “On the one hand, Merton has a load of money. But no one likes spending a million pounds.”last_img read more

Beach and Boardwalk Projects Continue in Ocean City

first_imgBEACHThe dredge Illinois is ready to pump sand onto the beach in Strathmere, and on Sunday was moored just off Corson’s Inlet.At the moment, the dredge Illinois is stationed near but not in Corson’s Inlet.The Great Lakes Dredge and Dock Company has been hired by the Army Corps of Engineers to return to a job it finished in September.The project brought 1.6 million cubic yards of sand to Ocean City’s south end. (By comparison, it would take only about 1.37 million cubic yards to fill the entire Empire State Building with sand (according to the Empire State Building fact sheet).But a northeast gale that arrived shortly after the completion of the project eroded a substantial amount of the new sand. The touch-up project will bring 323,000 cubic yards back to Ocean City.The work will begin in Strathmere and proceed to Sea Isle City before finishing up in Ocean City later this winter. The dredge is stationed just off Corson’s Inlet on Sunday (Jan. 3). Rows of pilings are in place near Eighth Street on Sunday (Jan. 3) as an Ocean City Boardwalk reconstruction project continues.center_img BOARDWALKThe Ocean City Boardwalk has been completely demolished between Plaza Place and Eighth Street, and a rows of pilings are now in place across a half-block of the work area.The installation of the substructure marks good progress in a project to reconstruct the one-and-a-half-block stretch of the boardwalk. The work is expected to be complete by mid-March, but with continued good weather and with sections of boardwalk decking already constructed off-site, the work possibly could be complete before then.The project is the third phase of a multiyear effort to rebuild the Ocean City Boardwalk between Fifth Street and 12th Street. Walters Marine Construction of Ocean View has a $1,888,347 contract to do the job.Boardwalk cyclists and pedestrians have been detoured around the construction area since October.last_img read more

Roll sales suffer, but hot weather may help

first_imgThe trend for making sandwiches at home to save on lunch bills, which has seen sales of sliced loaves soar, has not extended to bread rolls, which saw sales drop in the 12 weeks to 17 May.Figures from TNS Worldpanel show that sales of packaged plant rolls fell in value by 1.1% to £132.7m during the period, while value sales of ISB rolls fell 6.2% to £46m. Volumes grew 0.1% in plant rolls and fell 14.6% in ISB over the 12 weeks.The bakery buyer for one retailer told British Baker that the decline could be related to changing weather conditions. “Weather has a tremendous impact on sales of rolls – it’s the ’barbecue effect’,” he said. “Bread always does better when the weather is worse, but it will be interesting to see the sales figures for rolls for June. It’s been so hot that it’s bound to help sales.”last_img read more

Australian batteries pushing coal out of frequency control market, saving customers money

first_img FacebookTwitterLinkedInEmailPrint分享Renew Economy:The growth in number of big batteries in Australia’s main grid is displacing coal generation as a provider of frequency control and ancillary services (FCAS) markets, and helping reduce overall costs, according to the Australian Energy Market Operator.In its latest Quarterly Energy Dynamics report, AEMO says batteries have increased their share of key FCAS markets from 10 per cent in the last quarter of 2018 to 17 per cent in the first quarter of 2019, thanks to the recent addition of the Dalrymple battery storage plant in South Australia and the Ballarat battery storage facility in Victoria. Another interesting development is the increased share in the FCAS market for demand response services, which has upped its share from just under 10 per cent a year ago to 15 per cent now.That gives a 35 per cent share to “new technologies” and has in turn eaten into the share of the traditional coal generators, which have fallen from near 45 per cent to around 28 per cent.This – along with increased supply from hydro generators, including the Wivenhoe pumped storage supply in Queensland – helped overall costs fall by around 33 per cent from the last quarter to $36.4 million. Most of the cost reductions occurred in the contingency raise section of the FCAS market.AEMO notes that both pumped hydro and batteries have increased the amount of charging and pumping during the middle of the day, especially during the solar noon, soaking up the sponge of high solar output.Interestingly, batteries have also found a profitable new market during the morning (meeting early morning demand around 06:00-07:00), with both pumped hydro and batteries increasing generation during the evening peak.More: Big batteries displace coal, and lower costs in frequency markets Australian batteries pushing coal out of frequency control market, saving customers moneylast_img read more
