| 摘 要： | 岩溶作用是水对可溶性岩石进行的溶蚀作用，包括水的机械和崩塌作用以及物质的携出、转移和再沉积的综合地质作用。岩溶作用不但可以形成各种地表、地下岩溶形态和沉积堆积建造，同时在条件适合的情况下，还能聚积有用矿物形成矿床。因为岩溶成矿受特定条件的制约，并具有独特的环境特征。文章主要从构造的控矿性、可溶岩的含矿性、岩溶水的物化性状、热力学条件及聚矿空间的性质等，探讨广西中生代古岩溶的成矿环境，分析各种环境在岩溶成矿中的作用

| Abstract: | Karstification is mainly the chemical corrosion of water to soluble rocks, and also includes the mechanical erosion and the collapse as well as moving out, transporting and redepositing of matter. Karstification can not only form various types of surfacial and underground karst shapes and sedimentary formations, but also result in the formation of mineral deposits under given conditions. Karst mineralization is restricted by specific conditions, so it has unique characteristics.Based on the analysis on the ore-control characteristics of structures, the ore -bearing characteristics of soluble rocks, the physical and chemical characteristics and the thermodynamic conditions of karst water, and the characters of ore-impounding space, this paper mainly discusses the mineralizing environments of Mesozoic palaeokarst in Guangxi,and analyses the role of the various environments in the karst mineralization. |
