| 中文摘要: |
| 阿根他拉铁铜矿位于大兴安岭南段晚古生代增生造山带,产于二叠系下统黄岗梁组(P1h)钙泥砂质板岩和班布加拉嘎组(P1b)火山岩地层中,受北东向、近东西向断裂以及燕山期二长花岗岩控制。文章介绍了阿根他拉铁铜矿矿床地质特征,认为其成因为接触—充填型铁铜矿床。结合以往资料,认为该区的二区深边部、一区及三区圈定的磁异常,是下步找矿的潜力地段,该区除了找铁铜矿外,岩体与地层接触带、夕卡岩顶底板附近,也是找银多金属矿的有利地段。 |
| 英文摘要: |
| The Agentala iron-copper deposit is located in the southern part of Daxinganling belt, which belongs to late Paleozoic accretionary orogeny. The orebody is located in calcium silt slate of the Lower Permian huanggangliang group (P1h) and volcanic formations of Ban Bucharest Laga group (P1b). It is controlled by the north-east and nearly EW-trending faults and the Yanshanian magmatic intrusive. Geological characteristics of the Agentala iron-copper deposit is introduced in this paper, and the iron-copper deposit genesis belongs to the contact-filling type. According to previous researches, the authors pointed out that the magnetic anomlies outlined in the deep and edge area in area II, area I and area III are potential prospecting targets in the next step exploration. In addition to prospecting iron-copper orebodies, there are favorable locations for prospecting the silver orebodies in the contact zone of magnetic intrusives and surrounding rocks, the roof and footwall layers of skarn. |
