摘要
扎格拉金矿是河南省地质调查院新一轮国土资源调查在西藏通过水系沉积物测量和土壤测量发现的一个规模较大的岩金矿,取得了突破性进展。与此同时,在其外围通过1∶5万水系沉积物测量和1∶1万土壤测量发现了一批规模大、强度高、分带清晰、浓集中心明显的金异常,并与砷、锑异常套合较好,地质调查结果表明,西藏丁青一带具有较好成金地质背景。该金矿及其外围大规模金异常的发现说明利用水系沉积物、土壤测量在西藏地区找金是一种快速有效的方法。
The Zhagela gold mine was discovered through a combined chemical analysis of its water sediment and soil survey in which an anomaly of heavy gold powder was identified after regional geological survey on scale of 1：50000 water sediment and 1：10000 soil surveys on its perimeter show a host of large-scale, high-density, well-banded, and well-concentrated anomalies of gold, which are perfectly interlinked with arsenic and antimony anomalies, thus presenting golden prospects for finding minerals. The area has good minerogenetic conditions for gold. The discovery of the Zhagela gold deposit and its peripheral massive gold anomalies indicate the effectiveness of chemical analysis in searching for gold in that area. Fuller adoption of the chemical analysis method will lead to even more fruitful results in gold-finding in the area.
