摘要
在研究锡多金属矿床的主要控矿因素、成矿物质来源、主岩特征,地质环境、矿石建造和成矿作用特点后,将其矿床划分为岩控型、双控型和层控型3大类15个亚类;并对近年来找矿勘探工作中有突破性进展的花岗岩型、重熔斑岩型和同熔斑岩型矿床进行了详细地论述.在研究成矿物质来源、成矿作用问有机联系、矿床成因和矿床问规律分布的关系后,将锡多金属矿床划分为深源同熔岩浆、浅源重熔岩浆、双控、层控4个成矿系列,阐述了各成矿系列的综合特征;并分别建立了其成矿模式.
The tin-polymetallic deposits can be divided into three types including magmatic rock-controlling, magmatic and sedimentary controlling (double controlling) and stratabound types, and fifteen subtypes after studying major ore-controlling factors, source of ore-forming material, character of host rock, geologic environment, features of ore formation and metallization. The breakthrough advancement of exploration in recent years on granitic type, remelting porphyritic type and syntectic porphyritic type ore deposits was discussed in detail. After thorough research on internal relationship between ore-forming material source and metallizations, the relationship between ore genesis and ore deposits regular distribution, the tin-polymetallic deposits can be divided into four ore-forming series including deep-source syntectic magmatic, shallow-source remelting magmatic, double controlling and stratabound series. The synthetical features of each ore-forming series were discussed and their metallogenic models were established.
