四川叙永黄坭黏土矿地质特征及其成因分析

Geological Characteristics and Genesis Analysis of Huangni Clay Deposit in Xuyong,Sichuan

四川叙永黄坭伊利石黏土矿区内构造活动一般,岩浆活动和变质作用不发育,黏土矿层呈层状、似层状展布。综合区域构造、含矿地层、矿石矿物组构等特征,本文简要分析了该矿地质特征及成因,指出该矿床属于湖泊沼泽相沉积型矿床。

The tectonic activity in the Huangni illite clay mining area in Xuyong,Sichuan is normal,magmatic activity and metamorphism are not developed,and the clay deposits are spread in a layered and quasi-layered manner.Synthesizing the characteristics of regional structure,ore-bearing strata,ore and mineral fabric,etc.,this paper briefly analyzes the geological characteristics and genesis of the mine,and points out that the deposit is a lake-swamp sedimentary deposit.
