问题的提出众多事实说明,锡石硫化物型矿床与一定的花岗岩有关.但由于这类含锡花岗岩常为隐伏岩体.因此,研究花岗岩的含矿性,使用花岗岩含矿性的标志,预测锡矿化有一定的局限性.金属矿床的分带早在生产实践中应用于找矿.近年来,由于地球化学、矿物包裹体、同位素研究的进展,揭示了金属矿床的分带本质和形成机理,扩大了许多肉眼所不能见到的矿化现象,从而更有效地指导找矿,取得了一定的效益.
Many questions have been put forward that cassiterite-type deposits are related to certain granite, but because such tin-bearing granite is often a concealed mass, the study on the ore-bearing properties of granite is based on the prediction of granite-bearing mineralization Tin mineralization has its own limitations. The zonation of metal deposits has long been used for prospecting in production practice. In recent years, due to the progress of geochemistry, mineral inclusions and isotope studies, the zonation and formation of metal deposits have been revealed Mechanism, expanding the mineralization that many naked eyes can not see, so as to guide ore prospecting more effectively and achieve certain benefits.
