摘要
冀东金厂峪金矿为我国的黄金事业做出了突出贡献.但是随着多年开采,浅层矿体基本开采殆尽,为查证深部成矿空间,2022-2023年在矿区进行深部勘查,实施钻孔ZK6001,孔深 1 600 m,在钻孔内进行了激电测井和岩芯原生晕测量,通过岩芯物性测量、极化率异常和地球化学分析,在深部圈定出 2条金矿化体,其地层、构造、蚀变特征与上部含矿区的特征一致,表明金厂峪深部的矿化类型符合前人研究提出的矿化分带特征.特别是在揭露FI19断层及两侧的厚大含金矿化蚀变带,说明金厂峪深部存在金富集成矿的构造特征及物质来源,证明其深部存在第二个金富集中心.
Abstract
Jinchangyu Gold Deposit,Jidong has made outstanding contributions to China's gold industry.However,with years of mining,the shallow ore bodies have been basically exhausted.In order to verify the deep mineralization space,our unit conducted deep exploration in the mining area from 2022 to 2023,implementing borehole ZK6001 with a depth of 1 600 m.Induced polarization logging and core primary halo measurement are carried out in the borehole.Through core physical property measurement,polarization anomaly and geochemical analysis,two gold mineralization bodies are delineated in the deep.Their stratigraphic,structural and alteration characteristics are consistent with the characteristics of the upper ore bearing area,indicating that the mineralization type in the deep of Jinchangyu is in line with the mineralization zoning characteristics proposed by previous studies.Especially in exposing the FI19 fault and the thick and large gold mineralization alteration zones on both sides,it indicates the structural characteristics and material sources of gold rich integrated deposits in the deep of Jinchangyu,proving the existence of a second gold rich integrated center in its deep.
