【摘要】：石湖金礦床位于太行山中北段,礦床產(chǎn)出嚴格受斷裂構造控制。在詳細野外觀察及室內(nèi)綜合研究基礎上,結合礦山生產(chǎn)地質(zhì)資料的二次開發(fā),認為石湖金礦控礦構造是在前中生代近SN向和NW向剪節(jié)理基礎上,經(jīng)燕山期構造追蹤、疊加、復合而成。在主成礦期NNW-SSE向左行走滑應力作用下,石湖金礦區(qū)101脈控礦構造NW向部位以早期充填的石英閃長玢巖脈頂?shù)装鍨楸∪趺嫦鄬U容,相應地礦床圍巖蝕變帶變寬、礦化強度高、礦化類型以石英脈型為主,形成局部"富礦柱";而近SN向部位則相對空間壓縮,相應地圍巖蝕變帶變窄、礦化強度低、礦化類型以蝕變巖型為主,不利于成礦;富礦柱以高角度(約70°)側列式分布,各富礦柱聯(lián)合形成總體以40°向南側伏的假象。根據(jù)該構造控礦規(guī)律,預測石湖金礦101脈47~61勘探線間、標高150 m以下部位為有利成礦部位,該成果已為礦山生產(chǎn)所證實。
[Abstract]:Shihu gold deposit is located in the north of Taihang Mountain and its occurrence is strictly controlled by fault structure. On the basis of detailed field observation and laboratory comprehensive study, combined with the secondary development of mine production geological data, it is considered that the ore-controlling structure of Shihu gold deposit is based on the near SN and NW shear joints of the pre-Mesozoic, followed and superimposed by the Yanshanian tectonics. Compound. Under the action of NNW-SSE to left strike-slip stress during the main metallogenic period, the NW direction of the 101 vein controlling structure in Shihu gold deposit area is relatively enlarged with the early filling quartz diorite-porphyrite vein top and bottom plate as the weak surface, corresponding to which the alteration zone of the surrounding rock of the deposit becomes wider and the mineralization intensity is high. The mineralization type is mainly quartz vein type, forming local "rich ore column", while near SN direction is relatively space compression, corresponding wall rock alteration zone becomes narrow, mineralization intensity is low, and mineralization type is mainly altered rock type, which is not conducive to mineralization. The rich ore columns are distributed at high angles (about 70 擄), and all the rich pillars form the illusion that the south side of the ore-rich pillars is 40 擄in total. According to the rules of structural ore-control, it is predicted that between the exploration lines of Shihu gold deposit 101 vein 47jiu61, where the elevation below 150 m is favorable, the result has been proved by mine production.
