文章在分析云南东川杉木箐铁铜矿成矿地质背景和地质特征基础上,根据邻区东川式、稀矿山式铁铜矿的成矿条件和岩隆构造、重磁同现异常、化探异常、矿化等找矿信息,结合省地勘基金项目勘查的最新成果,对勘查区的找矿潜力进行了分析和研究。认为其成矿特征、物化探异常与落因铁铜矿带类似,圈定零公里至小坡和二百二至新寨等2条重磁同现异常带(岩隆构造带)及附近区段为有利找矿靶区,推测深部具有中-大型矿床规模的找矿潜力。
文章在分析雲南東川杉木箐鐵銅礦成礦地質揹景和地質特徵基礎上,根據鄰區東川式、稀礦山式鐵銅礦的成礦條件和巖隆構造、重磁同現異常、化探異常、礦化等找礦信息,結閤省地勘基金項目勘查的最新成果,對勘查區的找礦潛力進行瞭分析和研究。認為其成礦特徵、物化探異常與落因鐵銅礦帶類似,圈定零公裏至小坡和二百二至新寨等2條重磁同現異常帶(巖隆構造帶)及附近區段為有利找礦靶區,推測深部具有中-大型礦床規模的找礦潛力。

Based on an analysis of ore-forming geological background and geological characteristics of the Shanmuqing Fe-Cu deposit in Dongchuan of Yunnan Province and using the information in such aspects as the metallogenic conditions of Fe-Cu deposit of Dongchuan model, the Xikuangshan model of the neighboring area, the dome structure, the gravity-magnetic anomaly, the geochemical anomaly and the mineralization, in combination with the newest results in geological exploration of Yunnan Province, the authors analyzed and studied the ore-prospecting potential of the exploration area. Considering that its metallogenic characteristics and geophysical-geochemical anomaly are similar to those of the Luoyin Fe-Cu ore belt, the authors delineated two gravity-magnetic anomaly belts of Linggongli-Xiaopo and Erbaier-Xinzhai and their nearly areas as prospecting targets. It is inferred that there exists great prospecting potential in search for middle-large ore bodies at the depth.
