摘要
新疆和硕县可可乃克天青石矿矿床赋存于二叠纪阿其克布拉克组下段砾岩夹砂岩、粉砂岩、灰岩中,仅Ⅲ号矿体赋存在二叠纪闪长玢岩与阿其克布拉克组一段砂岩、粉砂岩、灰岩的接触带中,矿体形态严格受地层层位控制,层控特征明显,并受后期侵入岩侵入改造。通过对矿区内地层、控矿构造、侵入岩、矿体特征和矿石质量的分析论述,认为该矿床为沉积改造型天青石矿床。
Celestite deposit in Kokn Ik area of Heshuo coungy in Xinjiang Uygur Autonomous Region occurred in conglomerate sandstone, siltstone and limestone in lower part of Permian Aqike Braque group. Only III ore body exists in contact belt of sandstone, sihstone and limestone in the first section of Aqike Braque group and Permian diorite. Oreb ody shape is strictly controlled by strata with obvious ore-controlling characteristics, and is controlled by the late intrusive rock intrusion reconstruction. Through analyzing strata, ore controlling structures, intrusive rocks, characteristics of ore body and ore quality, it is regarded that this deposit is sedimentary reformed celestine deposit.
