山东蒙阴金刚石矿床地质大数据三维建模与成矿预测

Geological big data three-dimensional modelling and mineralization prediction of diamond deposit in Mengyin,Shandong,China

大数据时代的到来,需要我们在大数据思维指导下进行三维地质建模工作。笔者以山东蒙阴西峪金刚石矿作为为研究对象,基于大数据发现技术与大数据挖掘技术实现了传统三维地质建模工作和信息技术的深度融合,结合可视化表达等技术方法充分提取了文本数据中西峪金刚石矿的成因模式信息与地球物理勘探标准信息;并在此指导下完成了地球物理信息的解译工作,以期降低地球物理信息多解性对三维地质建模干扰,提高三维地质建模的准确性。最后,结合对成因模式与地球物理勘探标准的深入认识,文章实现了蒙阴金刚石深部含矿性分析,并初步圈定了成矿远景区。

The arrival of the big data era requires us to carry out three-dimensional(3D)geological modeling work under the guidance of a big data mindset.This research takes the Xiyu diamond deposit in Mengyin,Shandong Province,as the research object and achieves the deep integration of traditional 3D geological modeling work and information technology based on big data discovery technology and big data mining technology.In this research,the genetic type information and geophysical exploration criteria information of Xiyu diamond deposit in the text data is fully extracted through data discovery,data mining,and visible expression.The interpretation of geophysical information is completed under the guidance of data discovery and data mining to reduce multi-interpretations of the interference of geophysical information on the 3D geological modeling and improve the accuracy of the 3D geological modeling.Finally,combining the in-depth understanding of the genetic type and the geophysical exploration criteria,the analysis of deep mineralization has been realized,and the mineralization targets have been preliminarily defined.
