| In the Central Asian Orogenic Belt,the Paleozoic crust was highly proliferated and reformed,accompanied by multiple-stage and multi-type crust-mantle interactions and complex metallogenic processes,with excellent metallogenic geological conditions,among which Atasu-Zarr The Neiman metallogenic belt is located in central Kazakhstan and is located on the convergence zone of the Siberian plate and the Kazakh-Jungar plate structure,forming rich mineral resources.According to the statistical analysis of the number of ore deposits in the eight four-level metallogenic belts of Kazakhstan,there are more SEDEX-type large-scale mineral deposits in the metallogenic belt,resulting in the Sedex-type deposit of the Atashu-Zalirnaiman metallogenic belt.It is of great significance for China's resource strategy.Therefore,this paper evaluates the potential of these deposits.Due to the diverse forms of geological mineral information integration,various types of data involving different periods,different sources,different scales,different coordinate systems,and different formats are involved.At the same time,both ore prediction and resource potential assessment are at a relatively low level.Systematic,specific content,and scale are still unable to meet the resource potential assessment requirements of metallogenic belt scales,and GIS platform,as the mainstream of international spatial information,has high ease of use and good practicality,and is in line with mineral resources and geosciences.The way of thinking of workers is the only way for the informatization of geological and mineral resources in the future.Based on the geological characteristics within the metallogenic belt,this paper comprehensively collects the results of geology,mineral resources,and geochemistry in the research and analysis area.Combined with the international and domestic deposit model research,the SEDEX type Pb/Zn deposit model in the metallogenic belt is summarized to ARCGIS.Relying on the platform,the core idea is to use the “depository description model-spatial database-spatial analysis method” integration method to extract space through the application of key points such as tectonic conditions,surrounding rocks in the ore and mine,elemental combination anomalies,and predecessor metallurgical prediction results.Relevant information in the database,spatial analysis and weighted summation,resource potential analysis of SEDEX type Pb/Zn deposits in the Atasu-Zalirnai metallogenic belt,and “relevant prospects related to discovered deposits” And “remaining prospects related to deposits to be discovered”,three types of prospects were eventually obtained,including 16 I-type prospects,33 II-type prospects,and 60 type III prospects.The preliminary estimate was Atasu-Zalernay.The amount of SEDEX-type large-and medium-sized Pb/Zn deposits in the Mancheng metallogenic belt is 28.52 million tons. |
