| 3D Metallogenic Prediction Based on Metallogenic System Analysis:A Case Study in the Lala Copper Mine of Sichuan Province |
| With the development of mineral resources prediction, 3D quantitative prediction and evaluation of mineral resources has become a hot spot in the field of mineral exploration. However, the core for determining the success or failure of mineral prediction and exploration lies in how to construct appropriate prediction variables to reflect the mineralization process. Taking the Lala copper mine as an example, this paper summarizes the geological prospecting elements of mineral prediction in this area by analyzing the four elements of “source, transport, storage, protection” through the metallogenic system. Based on the 3D geological modeling technology and the quantitative extraction technology of metallogenic information, the 3D geological information of regional prospecting elements is constructed. Based on the information of prospecting information, the favorable zoning of the Lala copper deposit is determined and four prospecting target areas are delineated. This study combines metallogenic system analysis (knowledge-driven) with three-dimensional quantitative analysis (data-driven), converts the mineralization process and key factors (source, transport, storage, protection, etc.) into specific and predictable space elements, and the 3D visualization technology is used to reconstruct the 3D space. This method provides a good reference for the future 3D quantitative prediction. |
