摘要
金窝子金矿床位于新—甘边界地区哈密市境内,是北山地区最为重要的金矿床之一,断裂构造是矿床内最为重要的控矿因素。由F210韧脆性剪切断裂逆冲作用在金窝子岩体内形成的近NS向高角度追踪张性断裂是矿床的直接控矿构造,具体控制了金窝子金矿床石英脉型矿体的空间分布、形态和产状以及成矿元素的分布。断裂构造的脉动性活动则控制了成矿多阶段性。并指出了矿化富集和工业矿体就位的有利部位,以期对矿山下一步探矿工作有所帮助。
Jinwozi gold deposit, located in Hami city adjacent to Gansu province, is a most important gold deposit in Beishan area, where fault structure is the most immediate ore-controlLing factor. The near NS-deeply dipping exten- sion faults in Jinwozi mass formed by F210 ductile-brittle shear thrust are the main ore-controlling structures, specifical- ly controlling spatial distribution of auriferous quartz, vein shape, occurrence, and distribution of metallogenic ele- ments. The fault pulsation activities governed multi-mineralization. The author pointed out the favorable locations of the mineralization enrichment and economic orebody formation, which would help further exploration of the mine.
