英文摘要: The Nanling Scientific Drilling-1 of the Sinoprobe Progress( abbreviation as SP-NLSD-1) is situated at Yinkeng area, Yudu County,southern Jiangxi Province. Tectonically,it is located on the connection part of EW-trending Nanling structural-magmatic metallogenic belt and NE-trending Wuyi metallogenic belt,which is one of the best areas to do the research on the crustal structures and deep metallogenic mechanism. The NLSD-1 is started at June 25,2011,and finished at July 22,2013. The main borehole had been drilled to the depth of 2967. 83m,with all the cores had been in its position accurately. Our research team has built up a refined logging rule which is applicable to the scientific drilling in mining area. Meanwhile,the petrologic,structural,mineralization, geochemical,petrophysical and...
中文摘要: 国家深部探测-南岭科学钻探工程(SP-NLSD-1)位于赣南于都县银坑镇,大地构造位置上属于南岭东西向构造-岩浆-成矿带与武夷北东向成矿带的交汇结合部位,是研究重要成矿带地壳结构、深部成矿机制的最佳地区之一。南岭科学钻探于2011.6.25开孔,2013.7.22终孔,总进尺2967.83m,岩心已全部准确归位。课题组建立了矿集区内科学钻探的精细编录方法,建立了岩性、构造、矿化、地球化学、岩石物性等精细剖面。钻孔于1373.71m揭露了区域上控岩控矿的F1推覆构造,其上为青白口系库里组火山碎屑岩地层,其下为二叠系乐平组-车头组-小江边组(栖霞组)海陆交互相地层;揭露了丰富的岩浆活动信息,0~2000m共见29层花岗质岩浆岩脉,主要岩性有流纹斑岩、花岗斑岩、闪长玢岩和花岗闪长斑岩;发现了浅部细脉-网脉-浸染状铅锌铜金银矿化百余处,深部发现了细脉-浸染状钨铋矿化信息,初步实现了南岭科学钻探的预期目标。
