摘要
萨尔布拉克金矿化带位于额尔齐斯断裂带南侧下石炭统南明水组质凝灰质屑岩的挤压破碎带上,全长18km,呈北西—南东方向延伸。本文从晶形和粒度、化学成分、热电系数、晶胞参数、成矿温度、包裹体成分等方面分别对主要合金矿物毒砂、黄铁矿、石英等标型矿物进行研究,对矿区特有的草莓状黄铁矿、磁黄铁矿,以及自然金亦进行了研究。对成矿控矿地质条件和找矿标志进行了分析和总结。
The Sarbulak gold ore mineralization belt is located at the compressional kata-clastic belt in the carbonaceous tuffaceous kataclastic rock of the Lower Carboni-ferous Nanmingshui Group on the southern side of the Ertix fault zone. Its total length is 18km, and it trends toward NW-SE. The main Au-bearing minerals, such as arsenopyrite, pyrite and the typomorphic minerals, such as quartz, etc. are studied respectively according to their crystal form and grain size, chemical composition, coefficient of thermoelectricity, parameter of crystal cell, ore forming temperature and composition of inclusions. The strawberry-like pyrite (which is peculiar to the ore deposits), pyrrhotite and natural gold are also studied. Final-ly, the geological conditions for ore-control and ore-forming as well as prospect-ing criteria are analyzed and summarized.
