矽卡岩型矿床是矿床学上的一个重要成因类型。它在我国(特别是东部成矿域)已知矿产资源中占有突出的地位,在成矿作用和富集规律的研究方面也获得了许多有意义的成果,构成我国矿床理论和实践上的一大特色。根据矽卡岩型矿床的成矿控制因素,矿体与岩体和容矿岩层的关系,可把这类矿床归纳为几个“式”:(1)接触式(矿体就位于岩体接触带包括捕虏体接触带上);(2)层控式(矿体沿一定层位在外接触带作单层或多层产出);(3)裂隙充填式(脉状含矿矽卡岩沿裂隙充
Skarn deposits are an important genetic type in ore deposits. It occupies a prominent position in the known mineral resources in our country (especially the eastern metallogenic domain), and it also has obtained many meaningful achievements in the study of metallogenesis and enrichment law, which constitutes a theory and practice in our country Big features. According to the mineralization control factors of skarn deposits, the relation between ore bodies and rock mass and ore-bearing strata, these deposits can be summarized into several “types”: (1) The contact type With the inclusion of xenolith contact zone); (2) layer control (the ore body is exposed to a single layer or multiple layers along the outer contact zone); (3) fissure filling Fill along the crack
