新疆东昆仑西段铁矿预测区的圈定及资源量估算-基于ArcGIS平台
Delineation of the Predicted Iron Ore Areas and Resource Estimation for the Western Section of the East Kunlun in Xinjiang-Based on ArcGIS Platform
摘要
Abstract
The research area lies in the early Palaeozoic epicontinental active belt （Qimautage rift trough） of the Qaidam block in the north China plate,which was the early Palaeozoic magma type passive epicontinental in Qimantage. Based on the ArcGIS platform,taking the sedimentary-metamorphic type iron ores as an example, this paper constructs an evaluation model for iron resource potential, delineates the forecasted iron ore areas in the western section of the East Kunlun,and optimizes the target areas. As the sedimentary-metamorphic type iron ores are related with sedimentary formation and rock association, we infer that the major ore-controlling factors for iron mineralization include sedimentary formation, Fe geochemical anomalies and rock associ- ation in the region. We use sedimentary formation and Fe geochemical anomalies as the evidence to predict iron ore resources. There are three prospecting at~as,i, e. one A type and two C-type places, which are all of tile sedimentary nletamorphic type. After delineating the forecast areas of iron ores,we esti- mate the quantity of undiscovered ore deposits in these areas and simulate the distribution features,grade and tonnage about the ores in these areas. Then we estimate the resorce with dift）rent probability and make the evaluation of resource potential fast and accurately. The result indicates some resource po- tential of iron ores in the area. This study can serve the exploration and deployment work of iron ores in the western section of the East Kunlun.关键词
