| Based on the systematic collection and analysis of previous relatedgeological exploration and scientific research, Through field geologicalinvestigation and sample collection and laboratoryanalysis ofa largenumberoftest work,Adetailed analysis on the regionalstream sediment surveywerewrong, Identify the geochemical landscape area, the research area of theformation, the enrichment of oreprospecting target area etc. Rich explorationgeochemical indicators of theoretical knowledge of mineral.Geochemical map of15elements measured area, Objectively reflect thecharacteristics of the regional distribution and enrichment of elements;Combined with the geological, geochemical characteristics, Circle the25geochemical element anomaly; The5class B anomalies, abnormal10C,class D abnormal10. On the basis of the comprehensive study, divided into2geochemical zones,3geochemical zones; prospect area2grade Ⅰ, Ⅱ1prospect areas, for the future in this area to carry out exploration andprospecting work provides a veryvaluable information. Through the analysisand evaluation of the anomaly interpretation, pointing out the area in thefuture mainly looking for minerals for chromium ore, ore, antimony (gold)oreis animportant mineral.Throughtheanalysis ofgeochemicaldataresults,the early Jurassic Sewa formation (J2q) stratigraphic unit distribution area isthe comprehensive anomaly distribution region of main ore-formingelements. In the test area is a choice of6different elements combinationanomaly verification, the abnormal reproducible; confirmed by fieldsampling and sample analysis of reliable quality. Verification results to findAnglong chromite ore at1, Anglongnan fossa, east east polymetallic ore at2, obtained better prospecting results. Based on the geochemical characteristicsand tectonic background, survey area divided into2geochemical zones,3geochemicalpartition. Division3prospectingarea, wherein theprospect area2grade Ⅰ, Ⅱ1prospect areas, for the future prospecting direction. |
