白山市大横路铜钴矿区经过多年的地质勘探、控矿构造研究 ,认为该矿床属沉积变质型 ,层控比较明显。为了更深入地研究该矿床形成的地质条件 ,有必要对矿区含矿岩系原岩性质、沉积物来源、沉积环境等各方面进行更深入的研究。本文从岩石化学、微量元素地球化学、稀土元素地球化学等方面 ,分别进行了讨论。通过元素地球化学特征所反映的信息 ,来正确认识矿区内大栗子组原岩性质、沉积物来源、沉积环境等。
After many years of geological prospecting and ore-controlling structure research in the Dahenglu Cu-Co mining area in Baishan City, it is considered that the deposit belongs to sedimentary metamorphism and stratum control is obvious. In order to further study the geological conditions of the deposit, it is necessary to conduct a more in-depth study on the protolith characteristics, source of sediments and sedimentary environment of the ore-bearing rock series. This article discusses separately from the aspects of petrochemistry, trace element geochemistry and rare earth element geochemistry. Based on the information reflected by element geochemical characteristics, we can correctly understand the original lithology, sediment source and sedimentary environment of the large chestnut group in the mining area.
