摘要
双坑矿区位于浦城管查—建阳溪东铜多金属找矿远景区内,水系沉积物和土壤金属量测量异常规模大,套合好、峰值高,具明显的浓集中心。区内分布有铅锌银丰度值高的大金山组变质岩和燕山早期黑云母花岗岩,断裂裂隙发育,成矿地质条件有利。通过区域地质条件、异常元素组合与分布特征分析,探讨矿区找矿方向。
The Shuangk of the Pucheng G eng lead-zinc-silver minefield is situated at the ore-finding prospective area uancha-Jianyang Xidong polymetal minerogenetic belt. There are a large dimension of anomaly, a better telescopic and high peak values for the stream sediment and soil metallometric survey, in which there is an obvious concentration center. The lower Proterozoic Dajinshan Formation metamorphic rocks with a higher lead, zinc and silver abundance and early Yanshanian biotite-granite are distributed over the surveyed area. The developed faults and fissures are beneficial for the good geological conditions of the ore deposition. Based on the analyzing results of the assembly and distributional characteristics of anomaly elements under the regional geologic conditions, the author also presented an orefinding target of the minefield.
