摘要
庞家河金矿床地处秦岭造山带中西段的凤太多金属成矿带。矿区出露地层主要为泥盆系大草滩组,矿区构造类型多样,岩浆岩以花岗斑岩脉和辉绿岩脉为主。以原生叠加晕理论为指导,在矿区18号勘探线5个不同标高,采集了10种成矿元素的分析样品57件,通过对成矿元素统计学分析、原生晕轴向分带序列计算及各成矿元素异常分带特征研究,认为在庞家河矿区的18号勘探线深部矿体有较好的延伸。
Pangjiahe gold deposit is located at Fengtai polymetallic ore belt in the centralwest of Qinling orogenic belt.Devonian stratum,Dacaotan formation is mainly exposed in the mining area.The geological structure is complicated and magmatic rock is dominated by granite porphyry dykes and diabase dykes.This paper focuses on the18th exploration line.Under guidance of the primary halo suoerimposition theory57samples are collected at the five different levels at18th line to analyse the10different mineralization elements.We believe that ore body extents long to depth of18th line through systamatic statistics analysis and the calculation of axial zoning sequence of primary halo.
