贵州西部目前已探明大中小型菱铁矿床各一个,中型铅锌矿床一个.该区矿点星罗棋布,亟待进一步评价和工作. 该区铁矿,五十年代认为是铁帽型矿床.六十年代认为菱铁矿和铅锌矿均属低温热液交代充填矿床.七十年代以来,又先后提出了沉积改造和多源多次成矿的观点. 本文在综合了该区菱铁矿、铅锌矿同位素特征的基础上,结合矿床地质特点,就成矿物质来源、矿床成因进行了初步探讨,祈能有助于这类
There is one large, medium and small siderite iron ore deposit and one medium-sized lead-zinc deposit in the western part of Guizhou Province, which is dotted with lots of ore points for further evaluation and work. The iron ore in this area was considered as a cap-shaped deposit in the 1950s. In the decade, siderite and lead-zinc deposits were all considered to be low-temperature hydrothermal metasomatism deposits, and since the 1970s, depositional alteration and multi-source multiple metallogenesis have also been put forward.On the basis of synthesizing siderite, Based on the isotopic characteristics of lead-zinc ore and the geological characteristics of the deposit, the origin of the ore-forming materials and the genesis of the deposit are discussed.
