3D Geological Modeling Of Tongquanshan Ore Section In Shaxi Porphyry Copper Deposit In Anhui Province And The Indicative Significance Of Alteration Zone For Prospecting

With the rapid economic growth, energy minerals industry in the developmentof the national economy effect is increasingly distinct, mineral resourcesconsumption is correspondingly increased dramatically. Mineral resourcesshortage has become the constraints of our sustainable development bottleneck.Therefore, in the traditional prospecting method based on, looking for a quickand efficient prospecting method, is a brook no delay task. Computervisualization technology development makes the3D geological modelingtechnique in geological industry gradually arisen. Based on3D geologicalmodeling technique of true3D spatial data environment, geology andgeological environment can be more close to natural expression. It caneffectively establish tectonic evolution model, accurately determiningfavorable ore-forming tectonics, geologists recognize ground rule and orespatial distribution law, formulate the objective, scientific exploration, miningplan, reduce security risks, for the metallogenic prediction, prospecting workaided decision.This article takes the Anhui Shaxi Tongquanshan ore section as the researchobject, based on the collection of the geological data, with the help of miningsoftware Surpac to establish the Tongquanshan geological database, and onthis basis to complete the surface DTM model, geological model, rock massmodel, the main ore body model, alteration mineral model.“TheTongquanshan ore section of3D geological model”, in true3D environmentdirectly and accurately shows the Stratum, magmatic rock spatial distributionpattern in space. Based on the block model of the research area, this article usethe block model of the alteration mineral model in each exploration unitvolume distribution, alteration mineral model and the main ore body ofintersection block model volume distribution of the quantitative statisticalanalysis. Discussed the alteration mineral types relation with the main ore body. According to the results of quantitative statistical analysis, we got thesequence of the altered minerals development size order as follows: the blackmica, gypsum, kaolin, potassium feldspar, mica, chlorite. And the main orebody spatial most closely related to the alteration mineral is the black mica;sericite chlorite, kaolin, has certain instruction significance on the burieddepth; potassium feldspar, gypsum indicate the ore body boundary.
