岱王山金矿田是著名的赤峰-朝阳金矿化集中区内新近发现并勘查的一个重要金矿田,包括岱王山金矿及其东西两侧的峰水山金矿和中井金矿。它们并不是常见的产在老变质岩或岩浆岩中的高品位石英脉型金矿化,而是产在石炭纪砂板岩内的层控-层状的低品位蚀变岩型金矿化,是赤峰-朝阳金矿化集中区内一种新的金矿化类型。矿田内共划分出四条北东向矿化蚀变破碎带,圈定了82条金矿体。矿体多呈似层状、透镜状产在层间构造中,赋矿围岩主要为石炭纪轻微变质的砂板岩,金属矿物主要为黄铁矿和自然金。由于工作程度低,对矿床成因还无法做出较深的讨论。本文把矿田内的金矿成矿期次划分为3期:沉积期、热液成矿期和表生期。对该矿田内矿床地质勘查资料的综合研究表明,岱王山、峰水山和中井矿区的深部、矿区间连接部位以及岱王山矿区北侧和中井金矿西侧均有较好的找矿潜力。本文的结果将为今后同类金矿的找矿勘查提供重要参考。
Daiwangshan gold mine is a famous Chifeng - a newly discovered and explored gold deposit in the Chaoyang gold mineralization area, including the Daiwangshan Gold Mine and its Fengshui Mountain Gold Mine and Zhongjing Gold Mine on the east and west sides. They are not common high-grade quartz vein-type gold mineralization in the old metamorphic rocks or magmatic rocks, but rather are stratigraphic-stratiform, low-grade alterational-type gold mineralization within the Carboniferous sand- Is Chifeng - Chaoyang gold mineralization in a new type of gold mineralization. A total of four ore-forming alteration and crushing zones are delineated in the ore field, delineating 82 gold ore bodies. The orebodies are mostly stratified and lenticular in interlayer structure. The ore-controlling wall rocks are mainly metamorphic sandstone of Carboniferous, and the metal minerals are mainly pyrite and natural gold. Due to the low level of work, the genesis of the deposit can not make a deep discussion. In this paper, the gold mineralization in the orefield is divided into three phases: sedimentary period, hydrothermal mineralization period and epigenetic period. The comprehensive study on the geological prospecting data of the ore deposit in this field shows that there is a good prospecting prospect in the deep part of the Daishan Mountain, Fengshui Mountain and Zhongjing Mining Area, the connection between the mine area and the north side of the Daiwangshan Mining Area and the west side of the Zhongjing Gold Mine potential. The result of this paper will provide an important reference for prospecting exploration of similar gold mines in the future.
