通过对锡田钨锡多金属矿床地质特征的研究,认为锡田矿区钨锡多金属矿体的形态、产状及空间展布严格受岩体接触带及断裂构造控制;矿床类型主要为矽卡岩型,其次为破碎带蚀变岩型、云英岩型等;钨锡多金属成矿作用与岩浆活动密切相关:印支期花岗岩浆侵位形成矽卡岩型钨锡矿(化)体;燕山期花岗岩浆侵位导致早期矿化矽卡岩发生叠加矿化,同时在构造破碎带中形成云英岩型锡矿或破碎带蚀变岩型钨锡多金属矿体,是形成规模巨大的钨锡多金属工业矿床的必要条件。此外,提出了锡田矿区钨锡多金属矿的成矿模式。
Based on the study of the geological characteristics of the tin-tin-tungsten-polymetallic deposit, it is considered that the morphology, shape and spatial distribution of the tungsten-tin polymetallic ore body in the tin field are strictly controlled by the contact zone and fault structure of the rock mass. The types of deposits are mainly skarn Rock type, followed by alteration rock type and dolomite type in the crust; tungsten-tin polymetallic mineralization is closely related to magmatic activity: the Indosinian granitic magma emplaced to form skarn-type tungsten-tin ore ; The Yanshanian granitic magma emplacement resulted in the superimposition and mineralization of early skarn and the formation of dolostone or crustal alteration rock tungsten-tin polymetallic orebodies in the structural crust, Tungsten-tin polymetallic industrial deposits necessary conditions. In addition, the metallogenic model of tungsten-tin polymetallic ore in tin field is proposed.
