摘　　要：郴州市处于南岭成矿带中段,矿产资源丰富。区内碳酸钙类矿产主要分布于加里东期—燕山期岩浆岩外接触带的泥盆系—石炭系—二叠系碳酸盐岩地层中,受地层岩性与岩浆岩联合控制。其矿产类型以热变质作用形成的方解石矿与大理石矿为主,具有分布面积广、规模大、品质好、易加工等特点。系统地总结郴州市碳酸钙类矿产的分布、形态、产状、规模及控矿因素,提出碳酸钙类矿产的找矿方向。并初步分析出三个找矿靶区,即骑田岭岩体找矿靶区、大义山岩体找矿靶区和大东山岩体找矿靶区。Chenzhou City is located in the middle of Nanling metallogenic belt,mineral resources are abundant.Calcium carbonate minerals are mainly distributed in the Devonian-Carboniferous-Permian carbonate strata in the Caledonian-Yanshanian magmatic contact zone,which are controlled by both stratigraphic lithology and magmatic rocks.Its mineral types are mainly calcite and marble deposits formed by thermal metamorphism,which have the characteristics of wide distribution area,large scale,good quality and easy processing.This paper systematically summarizes the distribution,shape,occurrence,scale and ore-controlling factors of calcium carbonate minerals in Chenzhou,and preliminarily analyses the prospecting direction of calcium carbonate minerals.
