摘要
小龙河锡矿矿体产于花岗岩体与围岩的接触带中,燕山晚期的花岗岩浆侵入及不断演化为成矿提供了物质来源,随后的构造作用在岩体顶部形成的张剪节理,为矿质沉淀提供了空间场所。主要属气化-高温热液云英岩型锡矿床。
The ore body of Xiaolonghe Sn deposit is in the contact of granite and wall rock. The intrusion and continuous evolution of granite magma provide the material source for the metallogenesis. The tense-shear joint on the top of rock body formed by the later structural process provides the space for the precipitation of ore fluid. It belongs mainly to the pneumatolitic-high T hydrothermal greisen Sn deposit.
