腰子口滑石矿产于沉积岩中,它与岩浆岩和变质作用无关,为一新的沉积矿床类型。因色黑,故命名为黑滑石。矿点位于南相万盛火车站1.5公里,南半山坡上。近两年来我队对该点进行了系统的探槽,浅钻工程揭露,经普查评价后,其矿的地质特征简介如下;该点构造属南桐桃子荡向斜东翼,矿区小范围内地质构造极为简单,地层呈单斜,为南北向陡倾斜向西产出,倾角65—85°。出露地层为(由上而下):
Belt talc mineral deposits in sedimentary rocks, it has nothing to do with the magmatism and metamorphism, a new sedimentary deposit type. Because of color black, so named black talc. Mine is located in the South Phase Wansheng train station 1.5 kilometers, the southern half of the slope. In the past two years, our team conducted a systematic exploration of the site. After the shallow drilling project was exposed, the geology characteristics of the mine are summarized as follows: This point belongs to the east wing of the Nantong peach swinging to the anticline and within a small area of the mining area Geological structure is extremely simple, the formation was monoclinic, for the north-south steep tilt to the west, angle 65-85 °. Exposed strata (from top to bottom):
