摘要
本文通过对河南省方城县宋家庄金矿矿床地质特征、矿石类型及控矿因素进行分析,认为熊耳群的火山岩为该金矿提供了"矿源层",下汤-拐河深大断裂为含矿热液提供了通道,燕山期的火山活动为"矿源层"中金活化、运移、富集提供了动力。宋家庄金矿体的形成与区域地层、构造、岩浆活动关系密切。
Based on studying the geological characteristics, ore types and ore control factors of Songjiazhuang gold deposit, Fangcheng county, Henan Province, it is considered that the volcanic rocks of the Xiong＇er Group supplied the gold deposit with source beds, Xiatang-Guaihe deep fault supplied the ore-bearing solutions with passageways and the Yanshanian volcanic activities supplied activization, migration and enrichment of gold in source beds with motive forces. The formation of Songjiazhuang gold ore-bodies is closely related with regional stratigraphy, tectonics and magmatism.
