| 中文摘要: |
| 东天山卡拉塔格梅岭铜(金)矿床是在东天山地区新发现的矿床,赋存于一套基性—中性—酸性火山岩—火山碎屑岩和次火山岩中,由细脉浸染状和热液脉状的铜矿体组成。文章系统地研究了该矿床M1号矿体黄铁矿的热电性标型特征,结果表明:M1号矿体的黄铁矿热电导型以N型为主,总含量达到62.82%, 成矿温度主要集中于200~270℃,属于中低温矿床；黄铁矿热电导型及热电性参数特征反映出矿体被剥蚀到中部偏下的位置,向深部仍有一定规模的延伸。 |
| 英文摘要: |
| The Meiling deposit was newly discovered in eastern Tianshan mountain in recent years. The orebodies, which are hosted by basic- intermediate -acid volcanic rocks,volcano-clastic rocks and sub-volcanical rocks, consist of veinlet disseminated sulfide type orebodies and hydrothermal vein type ore bodies. The paper systematically studies the pyroelectricitical characteristics of pyrite mineral in the No. M1 orebody, and conclusions are summarized as followings:(1) pyroelectricitical properties of pyrites in No. M1 orebody mainly belongs to N type with a total content of 62.82%; (2)ore-forming temperature of the deposit ranges from 200℃ to 270℃, indicating that the deposit is a medium temperature hydrothermal gold deposit. The pyroelectricitical characteristics imply that the orebody has been eroded to middle part, and there is a trend of extension to the deep part of the No. M1 orebody. |
