Title:
SEABED SULFIDE ORE PROSPECTING METHOD BASED ON TOPOGRAPHIC ANALYSIS
Document Type and Number:
WIPO Patent Application WO/2020/042940
Kind Code:
A1
Abstract:
A seabed sulfide ore prospecting method based on topographic analysis, comprising the following steps: step 1: selecting a mineralization prospect zone; step 2: searching for topographic data of the mineralization prospect zone and drawing a seabed topographic map; step 3: analyzing the seabed topographic map, and planning and designing a sampling station; step 4: obtaining a sediment sample at the sampling station position in step 3; step 5: performing heavy sand mineral identification and main trace element analysis on the sediment sample, and drawing a seabed heavy mineral dispersion halo map and a geochemical halo map; step 6: performing overlay analysis on the seabed heavy mineral dispersion halo map and the geochemical halo map, and defining a favorable mineralization zone in combination with the topographic analysis. The method optimizes and innovates the sampling station setting of the seabed sediment, and the sampling station setting is more reasonable and effective; in combination with the heavy mineral and geochemical methods, a better detection effect is realized for inactive hydrothermal zone concealed sulfide and secondary enrichment mineralization; costs are lower compared with other methods.
