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。
National Deep Exploration - The Nanling Scientific Drilling Project (SP-NLSD-1) is located in Yinkeng Town, Yudu County, southern Jiangxi Province. The geotectonic location belongs to the Nanling east-west tectonomagmatic-ore belt and the Wuyi North East metallogenic belt It is one of the best areas to study the crustal structure and deep metallogenic mechanism of important metallogenic belt. Nanling scientific drilling in 2011.6.25 hole, 2013.7.22 final hole, the total footage 2967.83m, the core has all been accurately home. The research group established a fine cataloging method for scientific drilling in the ore concentration area and established fine sections such as lithology, structure, mineralization, geochemistry and petrophysical properties. Drilling at 1373.71m revealed the F1 nappe structure of the upper-controlled rock-controlling mine in the area, which is the volcaniclastic layer of the Quli Formation in the Qingbaikou Mouth. The Lower Permian Leping Formation-Cheertu-Xiaojiangbian Formation (Qixia Formation). The information of magmatic activity is revealed. A total of 29 granitic magmatic dikes are found in 0 ~ 2000m. The main lithologies are rhyolite porphyry, granite porphyry, diorite porphyrite and Granodiorite porphyry; found shallow vein - reticular - disseminated lead-zinc-copper-silver mineralization of more than 100, deep vein-disseminated tungsten-bismuth mineralization information found in the initial realization of the Nanling Science Expected goal of drilling.
