Annotated record of the detailed examination of Mn deposits from R.R.S. \"Discovery\" Cruise 11 stations

During Discovery Cruise 11, April-May 1966, eleven hauls were made on the crest and on the southern facing slope of Palmer Ridge in the Peake Deep area in order to fill out the information gained last year. Limestones were collected ranging in age from lowest Eocene through to Upper Tertiary, and several hauls successfully sampled the basement beneath these, producing weathered basalts, metamorphosed basalts and dolerites. In Peake Deep on the north slope of Palmer Ridge hard Eocene sediments were core sampled near the base of the slope but no cores could be got near the top.

1966年4至5月，在“发现号”第11次科考航次（Discovery Cruise 11）期间，为补充完善去年获取的调查资料，科研人员在皮克海渊（Peake Deep）区域内的帕尔默海岭（Palmer Ridge）脊顶与南坡开展了11次拖网取样作业。本次取样所获的石灰岩年代跨度从始新世早期直至晚第三纪，另有数次拖网取样成功获取了该套沉积层下方的基底样品，包括风化玄武岩、变质玄武岩与辉绿岩。在帕尔默海岭北坡的皮克海渊区域，科研人员在坡底附近对固结的始新世沉积物开展了岩心取样，但在坡顶区域未能获取岩心样品。
