摘要
通过湘南地区瑶岗仙、横山岭、宝山、黄沙坪、香花岭、铜山岭、水口山等矿区大量方解石样品的研究，得出方解石中镁铁锰含量变化与方解石的产状关系密切，从围岩到矿体方解石的镁铁锰含量增加；从成矿早期到成矿晚期，由富镁变为富锰；区域上，以郴州临武断裂带为界，断裂带附近及其东南侧各矿区矿体内方解石的平均镁铁锰含量明显地高于西北侧各矿区矿床内的方解石。
Stucy of a great nun1ber of calcites from mines of Yaogang-xian, Hengshanling,Baoshan, Huang-shaping,Xianghualing’Tongshanling.Shuikoushan and so on shows that the variation of Mg-Fe-Mn in calcites is closelyrelated to calcites occurrence. Contents of Mg-FeMn in calcite increase gradually from country rock to ore body and Mg-rich calcite changes its nature to Mn-rich one fro early to late periods of mineralization. Re-gionally chenzhou-Linwu fault zone,as a boundary,divides calcites into two categories:calcites in the mines near or in the southeast part to the fault and calcites in the mines in the northwest side. In the former the aver-age contents of Mg-FeMn are obviously higher than those of the latter.
