皖南里桥地区的控矿构造及矿质来源

Ore-controlling Structure and Source Material of the Liqiao Area, in Southern Anhui Province

控矿因素和矿质来源是探讨矿床成因的两个重要方面.本文从矿体的形态和赋存部位分析控矿构造特征,用微量元素和同位素资料分析矿质来源,目的是探讨里桥地区多金属矿床的成因,指出今后的找矿方向.

A study of the ore controlling factors and the sources of ore materials is of great importance to ascertain the origin of a mineral deposit. With a purpose of studying the genesis of the polymetallic deposits in the Liqiao area, Southern Anhui and pointing the way for future ore exploration, the ore-control structural features are analysed based on the shape and position of occurrence of the ore-bodies, and the source materials are studied in the light of trace element and isotope data.
