3D Metallogenic Prediction Based on Minerogenetic Series:A Case Study in Tongling Mineral District of Anhui
In order to quantitatively predict the underlying mineral resources in Tongling mineral district and im-plement mixed genesis prediction according to the different deposit types,3D metallogenic prediction based on minerogenic series is imperative.In this paper,we summarized two minerogenic series on the basis of previous studies,including the minerogenic series related to the Yanshanian magmatism and the sedimentary-reformation (metamorphic)minerogenic series.In addition,we summarized the porphyry-skarn-hydrothermal metallogenic model in the study area.Using 3D visualization technology,the 3D digital mine is modeled.After that,by im-plementing “cubic predicting model”prospecting method,we carried out a three-dimensional metallogenic pre-diction in the study area,and delineated 14 predicted targets according to the value of information and geolo-gical condition.Our research combines the traditional two-dimensional regional metallogenic prediction methods with advanced visualization technologies successfully,and extends the prediction of mineral resources within the region to three-dimensional space,makes it more conducive to concealed ore delineation work within the re-gion,and also provides a reference for future three-dimensional prediction.
