中文摘要
桂西碳酸盐岩区的方解石脉型、石英脉型和矿化晶洞型水晶矿床分布广、规模大、晶体质量好,但矿床远离火成岩体,水晶矿床成矿流体中的硅质来源不清楚,成矿溶液的来源尚有争议。本项目从成矿物质来源、成矿环境条件及其变化来探讨和研究碳酸盐岩区不同类型水晶矿的形成机理。通过水晶与围岩的成分、硅氧同位素以及水晶中包裹体的氢氧同位素与围岩氧同位素的对比研究,探讨和确定碳酸盐岩区不同类型水晶矿成矿的硅质来源和成矿溶液的来源;对不同类型水晶矿中的矿物组合、晶体形貌、包裹体特征的系统研究,探讨成矿环境条件及其演变过程;实验模拟不同环境条件下成矿介质对碳酸盐岩中硅的溶解以及水晶的生长情况,探讨碳酸盐岩的成分、水晶的成矿环境条件及其变化与SiO2结晶生长的关系。项目研究将加深对碳酸盐岩区不同类型水晶矿形成机理的认识,丰富和完善石英的矿物学和成因内容,对水晶矿床的勘查具有重要的指导意义。
英文摘要
Calcite vein quartz deposits, quartz vein type crystal deposit and mineralized druse quartz deposit are widely distributed in the carbonate rock area of Western Guangxi, the crystal deposits are large in scale, and good quality of the crystal. However, the quartz deposit in the carbonate rock area of Western Guangxi is far away from igneous rock mass, and the source of silicon in the deposit is not clear, and the source of ore-forming fluid is still controversial. This study will explore and reveal the formation mechanism of different types of quartz deposits in carbonate rock area from the sources of mineralizing materials, metallogenic environment conditions and its evolution. To explore the source of ore-forming materials, the chemical composition of quartz and surrounding rocks, silicon-oxygen isotopes of quartz and surrounding rocks, hydrogen- Oxygen isotopes of inclusions in quartz crystals and oxygen isotopes of surrounding rocks will be contrasted study. In order to study the environmental conditions of mineralization and its evolution, the characteristics of mineral assemblages, crystal morphologies, and inclusions in quartz crystals will be studied in detail. In order to explore the relationship between the chemical composition of carbonate rocks and the crystallization of SiO2, the relationship between the metallogenic environment conditions and the crystallization of SiO2, and the relationship between the changes of metallogenic environment conditions and the crystallization of SiO2, the dissolution of silicon in carbonate rocks by ore-forming solution under different environmental conditions is simulated by hydrothermal method, and quartz crystal growth is simulated by hydrothermal method under different environmental conditions. The project research will deepen the understanding of the formation mechanism of different types of quartz deposits in carbonate rock area, enrich and improve the mineralogical and genetic theory of quartz. Moreover, the project research will have important guiding significance for the exploration of quartz crystal deposits.
