河北榆成银金矿成矿地质特征研究
|
摘要
矿区位于易县南榆成镇,地处太行山北段东麓低中山区,地形西北高、东南低,起伏较大。矿区位于构造活动地区,区内构造、岩浆岩发育,地层主要有太古界阜平群片麻岩、中元古界地层以灰岩为主。本文通过对矿区区域地质、地球化学资料、槽探钻探工程资料、围岩蚀变特征等对榆成银金矿区成矿地质特征进行分析。
The mining area is located in Nanxuncheng Town, Yi County. It is located in the low-lying mountainous area of Dongpu Mountain in the northern part of Taihang Mountain. The terrain is high in the northwest and low in the southeast. The mining area is located in the tectonic activity area, and the tectonic and magmatic rocks are developed in the area. The strata are mainly composed of the Paleozoic Yuping Group gneiss and the Mesoproterozoic strata, mainly limestone.This paper analyzes the geological characteristics of the ore-forming gold deposits in the Yingcheng silver deposit by analyzing the geology, geochemical data, trench drilling engineering data and surrounding rock alteration characteristics of the mining area.
