广东凡口铅锌矿床成矿地质特征及资源预测

Concentrates Rule and Ore Body Predicting of Fankou Lead-Zinc Mine,Guangdong

凡口铅锌矿属特大型矿床,是粤北最重要的有色金属基地之一。近年来,凡口矿区陆续发现了一些厚大矿体,新增铅锌资源量近100×104t,初步显示出该矿区良好的找矿前景。通过对该矿床地质勘查及矿山开采资料的研究表明,凡口铅锌矿除受地层因素的制约外,还受到构造破碎带空间展部的限制,主要矿体受印支-燕山期形成的NE-NNE向构造带及其层间滑脱构造控制;进而指出今后找矿工作应部署在NE向构造带的延伸处以及其与早期NW向构造的交汇地带。

Fankou lead -zinc mine is the extra large type scale the deposit, there are near thousands of ton to prove up the lead zinc resources reserves. In recent years, along with the prospecting technology method progress and the mineralization theory deepening, Fankou mining area had discovered one after another some thick big ore bodies, the additional lead zinc amount of resources near 1,000,000 tons, initially demonstrate this mining area good prospecting prospect. Through to this ore deposit geology investigation and the mine mining material system reorganization, knew Fankou lead - zinc mine besides receives the stratum factor the restriction, mainly also receives the structure crushed zone space to unfold a limit. In fact, the main ore body receives the NE structure belt and the between stratum slides structure control, the Shiling Nan＇s vein ore body the NNW to the structure belt control, in the mining area grows a group NNE to structures （F2 -F10） as well as the between stratum slides structure by broken ore primarily. Further prospects should deploy the NE structure belt extends place as well as NE structure belt and NW structure belt west of the early time in connection region.
