摘　　要：研究区位于我国重要的金属矿床区域——西准噶尔成矿带。金异常区地层主要为包古图组第一岩性段组成(C1b),岩石组合以凝灰质粉砂岩、粗砂岩为主,褐铁矿化蚀变沿节理、裂隙发育,是本区主要含矿层。从已开采的阿达依金矿调查发现,金同黄铁矿及二氧化硅共生组合,含金矿物颗粒较细。因此,依据化探异常该区的找矿标志为构造蚀变带、硅化带。The study area is located in the West Junggar metallogenic belt,an important metal deposit area in China.The strata in the gold anomaly area are mainly composed of the first lithologic section (C1b) of Baogutu formation.The rock association is mainly tuffaceous siltstone and coarse sandstone.The limonitization alteration develops along the joints and fissures,which is the main ore bearing bed in this area.The investigation of adayi gold deposit shows that gold is associated with pyrite and silica,and the gold bearing minerals are fine.Therefore,according to the geochemical anomalies,the prospecting criteria of this area are structural alteration zone and silicified zone.
