本文试图从汞矿的成矿地质作用着手,结合硒的地球化学习性,运用数理统计方法,对湘黔汞矿带湖南境内诸汞矿床硒的赋存特征及其地质意义进行探讨。一、区域地质背景及矿床概况湘黔汞矿带位于凤凰—新晃大背斜西翼,保(靖)—铜(仁)深大断裂东侧,呈北北东向展布(图1)。而矿田(矿床)则多位于轴向北西西的横跨褶皱构造内。区内主要出露地层为寒武系,次为震旦系,均呈北东—南西向分布。花岗岩类除西部的梵净山(贵州省境内)见有侵入外,其它地区末曾发现。
Based on the geochemical behavior of selenium and the mathematical statistics, this paper attempts to discuss the occurrence characteristics of selenium and its geological significance of various mercury deposits in Hunan Province in Hunan-Guizhou mercury mining belt. I. Regional Geological Backgrounds and Mineral Deposits The Xiangqian mercury ore belt is located in the north wing of the Fenghuang-Sinkang anticline and east of the deep (Baoji) . The minefields (deposits) are mostly located in the axial northwestern West within the fold structure. The main exposed strata in the area are Cambrian and secondarily Sinian, all of which show a north-east-south-west distribution. Granite in addition to the west of the Fanjingshan (Guizhou Province) see the invasion, other regions have been found.
