摘要:泰国中部的锡矿化产于泰一缅交界处山脉中的花岗岩(西部组)中。曼谷东部的花岗岩侵入体和柬埔寨边境附近的花岗岩(东部组)则没有锡矿产出。结晶分离影响是基本的成岩影响泰语论文网站,并控制着两组花岗岩的演化。西部组的含锡碱性长石淡色花岗岩表现出分异的最终程度,而在东部组找不到这样相应的岩性特征。这些淡色花岗岩是岩浆结晶分离影响(具原生锡富集特征)、并受到流体改造影响所联合影响的产物。流体影响导致了锡的次生。地球化学贫化,泰语论文网站,又受到裂隙系统内锡的再分配(即矿化影响)而平衡。这种淡色花岗岩的锡贫化方式关于已知成矿系统提供了锡的远景标志。

Abstract:In the middle of Thailand tin production in Thailand Burma at the junction of the mountains (Western Group) in granite. East of Bangkok near the Kampuchea border and granite granite (Eastern Group) is no tin output. Crystallization and separation are the basic rock forming processes, and control the evolution of the two groups of granite. Western groups containing tin alkali feldspar leucogranite performance difference to the ultimate degree, and in the eastern group could not be found so that the corresponding lithological characters. These leucogranite is magmatic fractional crystallization (primary tin enrichment characteristics), and by the fluid transformation of the role of the combined effect of the product. Fluid action causes the secondary of tin. Geochemical dilution, and by redistribution of fissure system (i.e. tin mineralization) and balance. This leucogranite tin dilution for the known metallogenic system provides the prospect of tin sign.
