钨、锡、钼、铋是我国的优势矿产,其探明储量均居世界前列,而且成矿地质条件优越,只有良好的发展前景.现就这些矿床的成岩成矿系列和物质来源问题作一初步探讨,不当之处,请批评指正. 成岩成矿系列同一物质来源,在同一岩浆作用(或成岩作用)旋回演化过程中,不同阶段形成的一系列岩石以及伴随形成的一系列矿床,构成了一个有亲缘关系的成岩成矿系列.我国的钨、锡、钼、铋矿床均与花岗岩类有密切的成因联系.它们初步可划分为三个物质来源、形成机理不同,具有不同岩浆演化及成矿特点的成岩成矿系列,即: Tungsten, tin, molybdenum, bismuth is the dominant mineral in our country, and the proven reserves rank the forefront in the world, and the geological conditions of the ore are superior with only good prospects for development. Now we are going to make a series of studies on the diagenetic mineralization series and material sources of these deposits A series of rocks formed at different stages during the same magmatic cycle (or diagenesis) and a series of mineral deposits formed during the same magmatism (or diagenesis) A related series of diagenetic metallogenic series.The tungsten, tin, molybdenum and bismuth deposits in China are closely related to the granitoids.They can be divided into three material sources initially, with different formation mechanisms, different magmatic evolution and Mineral characteristics of diagenesis and mineralization series, namely:
