广西那北方解石矿地质特征及成因分析

Geological Characteristics and Genesis of Nabei Calcite Deposit in Guangxi

那北方解石矿床位于扬子克拉通东南缘,桂中—桂东北坳陷西部。矿区内地层简单,褶皱不发育,断裂构造十分发育。断裂构造主要为北北西向、北北东向两组。4个矿体均受构造控制,矿体规模大小不一,矿石成分单一,矿体以脉状为主。通过样品分析评价,整体矿石质量较好。属于低温热液充填型。

The Nabei calcite deposit is located in the southeast margin of the Yangtze Craton and the west of the Zhong-Northeast Guangxi depression.In the inner part of the mining area,the strata are simple,the folds are not developed,and the fault structures are well developed.The fault structure is mainly north-NW trending and north-NE trending.Four ore bodies were controlled by structure,the size of ore bodies is different,the ore composition is single,and the ore bodies are mainly vein shaped.Through sample analysis and evaluation,the overall ore quality is good.It belongs to low temperature hydrothermal filling type.
