陕西商丹地区伟晶花岗岩型铀矿床“三位一体”找矿预测地质模型

Study on the prediction geological model of "Trinity" ore prospecting in the pegmatite type uranium deposit of the Shangdan area in Shaanxi

陕西商丹地区铀矿床是伟晶花岗岩型铀矿勘查程度最高、找矿成果最显著的地区。在充分收集地质、物化探、工程等资料基础上,运用2D/3DGIS可视化技术,结合商丹地区以往资料和最新成果资料,对查明的伟晶花岗岩型铀矿床各种数据进行系统提取,初步建立伟晶花岗岩型铀矿多维多尺度找矿预测地质模型,并对陕西省商-丹地区伟晶花岗岩型铀矿有利地段进行了预测。

The Shangdan uranium deposits in Shaanxi Province are the areas with the highest degree of exploration of the Weijing granite-type uranium deposits and the most significant prospecting results. Based on the full collection of geological,geophysical and geochemical exploration and engineering data,the 2D/3D GIS visualization technology was combined with the previous data and latest results of the Shangdan area to systematically extract various data from the identified Weijing granite-type uranium deposits. A multi-dimensional multi-scale prediction ore-prediction geological model for the Weijing granite uranium deposit was established,and a prediction was made for a favorable section of the Weijing granite-type uranium deposit in the Shangdan area of Shaanxi Province.
