安徽贵池地区是长江中下游成矿带的重要组成部分,区内金、银、铜、钼、硫等矿产资源丰富。系统研究了贵池地区地质、岩浆岩、地球化学-地球物理等特征与金银多金属矿床的成矿关系,对抛刀岭金矿、乌石金及多金属矿、朱家冲金矿、铜山铜矿等多金属矿进行详细分析,总结各岩体的地球化学属性,并对贵池地区斑岩型矿床进行了重点研究,分析其成矿专属性。将贵池地区成岩成矿时间划分为两期:第一期是140 Ma左右的岩浆活动及成矿作用,为早白垩世(燕山早期),主要与铜金矿床有关;第二期是125 Ma左右的岩浆活动及成矿作用,主要与钼(铜)矿床(化)有关。这两期岩浆活动及成矿作用包括高钾钙碱性、碱性两个成岩系列,岩石类型以中酸性—酸性花岗闪长岩、花岗岩为主,与长江中下游地区其他矿集区的成矿作用类似。将地质标志、地球物理标志以及地球化学标志结合,建立了该区找矿标志,从而有助于区内金、银(铅锌)及铜钼等金属矿成矿理论的丰富及成矿规律的认识,为区内找矿突破提供科学依据。 The Guichi area in Anhui is an important part of the metallogenic belt in the middle and lower reaches of the Yangtze River. The gold, silver, copper, molybdenum and sulfur in the area are rich in mineral resources. The relationship between geology, magmatic rocks, geochemistry and geophysics in Guichi area and the metallogenic relationship of gold, silver and polymetallic deposits has been systematically investigated. Copper ore and other polymetallic deposits for a detailed analysis of the geochemical properties of the rock, and porphyry deposits in Guichi area has been the focus of research to analyze the mineralization specificity. The diagenesis and mineralization time in Guichi area is divided into two phases: the first stage is the magmatic activity and mineralization of about 140 Ma, which is Early Cretaceous (early Yanshanian) and mainly related to copper and gold deposits; the second is 125 Ma Magmatic activity and mineralization around, mainly with the molybdenum (copper) deposits (chemical) related. The two phases of magmatism and mineralization include two types of high-K calc-alkaline and basic diagenetic series. The types of rocks are mainly acidic-acidic granodiorite and granite, and are similar to other mineral deposits in the middle and lower reaches of the Yangtze River Similar mineralization. The geological markers, geophysical markers and geochemical signs combined with the establishment of a sign of prospecting in the area, which is conducive to the regional gold, silver (lead, zinc) and copper and molybdenum metal mineralization and other metallogenic enrichment and metallogenic regularity Understanding, provide a scientific basis for the prospecting breakthrough in the area.
