莱州市纱岭矿区金矿地质特征及其找矿前景

摘要

A number of large and medium sized gold deposits have been found in Jiaojia metallogenic belt, but the occurrence elevation of the ore bodies is more than 940m. Another large gold deposit has been found in Sha⁃ling mining area in Jiaojia metallogenic belt under the elevation of 940m. In this area, 184 gold ore bodies have also been found. Among them, 3 ore bodies can reach the size ofⅠtype, and 3 ore bodies can reach the size ofⅡtype. The gold (332+333) metal quantity is nearly 390t. In this paper, geological characteristics of ore bodies in the mining area have been studied, ore prospecting marks have been comprehensively sorted out, and ore prospec⁃ting future in deep part of Shaling mining area has been pointed out.%焦家成矿带发现多个超大型、大中型金矿床，但其矿体赋存标高均在940 m以上。纱岭矿区于焦家成矿带940 m以下再次发现超大型金矿，攻深找盲取得重大突破。发现金矿体184个，其中规模达第Ⅰ勘查类型的矿体3个，达第Ⅱ勘查类型的矿体3个。提交金矿（332）＋（333）金金属量近390 t。该文对矿区内的矿体地质特征进行研究，对找矿标志等进行综合整理，指出了纱岭矿区深部找矿远景。
