甘肃北贵多金属矿成矿地质特征及成因分析

Geological characteristics and genesis analysis of precious polymetallic deposits in northern Gansu Province

通过综合地质调查和数据分析,可知甘肃北贵地区多金属矿床的成矿地质特征和成因,能够为矿产资源开发提供可靠依据。该地区矿床主要分布于中石炭纪红柳园组地层和华力西晚期侵入岩之中,受到显著的区域性大断裂及其次级断裂的控制。此外,矿床形成与岩浆活动及热液流动紧密相关。本文还进一步确定一系列明确的找矿标志,包括围岩类型、构造特征、岩浆岩特征、地球化学异常及蚀变特征,为今后的勘探活动提供了重要的科学指导。

Through comprehensive geological surveys and data analysis,it is known that the ore-forming geological characteristics and genesis of polymetallic deposits in the northern Guizhou region of Gansu Province can provide reliable basis for mineral resource development.The mineral deposits in this area are mainly distributed in the Red Liuyuan Formation of the Middle Carboniferous and the late Variscan intrusive rocks,and are controlled by significant regional faults and their secondary faults.In addition,the formation of mineral deposits is closely related to magmatic activity and hydrothermal flow.This article further identifies a series of clear prospecting indicators,including surrounding rock types,structural features,magmatic rock features,geochemical anomalies,and alteration features,providing important scientific guidance for future exploration activities.
