摘要
北淮阳构造带隶属于秦祁昆成矿域秦岭-大别金、银、铅、锌、铜、锰成矿带。银沙地区即位于北淮阳构造带东段(安徽境内)的西部。区内中生代岩浆活动强烈,铅、锌、钼多金属矿化发育,成岩与成矿密切相关。本文通过对中生代岩浆岩的岩石化学、微量元素和稀土元素的研究来探讨岩浆岩成因和形成环境,从而了解该区矿床形成的岩浆岩背景,也为该区的进一步找矿提供理论依据。
The North Huaiyang structural belt belongs to the Qinling-Dabie gold, silver, lead, zinc, copper and manganese mineralization belt of the Qin-Qi-Kun metalogenetic province. The Yinsha area lies in the west of the eastern section of the North Huaiyang structural belt （in Anhui）, where Mesozoic magmatism is intense, lead-zinc, molybdenum and polymetallic mineralization are developed, and diagenesis is closely related to mineralization. This paper, based on petrochemical, trace element and REE studies of the Mesozoic igneous rocks, discussed the genesis and formation environment of the rocks as well as the igneous rocks context in which the deposits were formed in the area, providing theoretical basis for further prospecting of ores in the area.
