摘要
为探测相山火山盆地-3 000 m以浅主要目标地质体的空间分布为主要目的,在充分收集原有地、物、钻、坑等资料的基础上,以GOCAD软件为建模平台,根据19条MT地质解译剖面,结合1∶50 000地质图,并将钻孔、勘探线剖面等数据作为约束条件,构建了相山火山盆地三维地质结构模型。该模型能够高效表达深部地质信息,具空间关系的确定性、可动态编辑与更新、分析和计算功能等功能,为揭示相山火山盆地三维结构和深部找矿提供了实用、直观的信息。根据空间上的铀矿化规律进行深部成矿预测并圈定了2处铀成矿有利部位。
In order to figure out the geological bodies spetial characteristics less than 3000 m, and integrating data of geological, geophysical, drilling and mining is needed, with GOCAD software as platform,19 MT profiles as the main modeling data, companied by 1：50 000 geological maps, prospecting profiles, trench, drill logging, and finally establish 3D geological model of Xiangshan volcanic basin.The 3D model can efficiently express the deep geological information, Data in3 D model could be updated, dynamic edited, determine the spetial relationships, analysis and calculation, etc., it provides a practical, intuitive information toreceal the deep geological structure and metallogenic prediction. According to the Uranium mineralization regularity in space, predict and select two favourable areas for ore formation.
