Dredge Samples from SS2011_06

Dredge rocks were recovered on scientific voyage SS2011_06 on the MNF RV Southern Surveyor, from the Perth Abyssal Plain, offshore Western Australia. Continental rocks (gneiss, granite, sandstone) were dredged from both the Batavia Knoll and the Gulden Draak Ridge (dredge sites 1, 2, and 3). A small amount of high weathered basalt was recovered from the Gulden Draak Ridge (dredge site 4). Three successful dredges were undertaken along the Dirck Hartog Ridge recovering predominantly gabbro (dredge 5) and basalts (dredge sites 6 and 7).本数据集的岩石样品采自西澳大利亚近海的珀斯深海平原（Perth Abyssal Plain），由MNF RV Southern Surveyor科考船执行的SS2011_06科考航次通过拖网方式获取。 研究人员分别在巴达维亚海丘（Batavia Knoll）与古尔登德拉克海岭（Gulden Draak Ridge）的拖网站位1、2、3处，采获了大陆岩石样品，涵盖片麻岩（gneiss）、花岗岩（granite）与砂岩（sandstone）。 在古尔登德拉克海岭的拖网站位4处，还采获了少量高度风化的玄武岩（basalt）。 研究团队在德克哈托格海岭（Dirck Hartog Ridge）沿线开展了3次成功的拖网取样作业，其中拖网站位5主要采获辉长岩（gabbro），拖网站位6与7则采获玄武岩（basalt）样品。
