Feature Research On Strata Geochemistry Of Northern Guilin

The mineral resources in the northern Guangxi area are abundant and varied.The minerals mainly include tungsten,tin,copper,lead and zinc.The mineralization is mainly distributed on the contact zone between the rock mass and the stratum.Predecessors have conducted more detailed research on the relationship between granite and mineralization.However,it has not conducted in-depth research on the formations where various elements are enriched and activities are closely related.In northern Guangxi,there is a huge layer of shallow metamorphic sedimentary strata,study it in detail,it is very beneficial to have a deeper understanding of the evolution process and element rich minerals in northern Guangxi.The three regions of Yuecheng,Maoershan,and Longsheng in the northern part of Guangxi are selected as research areas,analysis of formation samples and magmatic rocks in the area and combining previous data.Comparing the traditional data processing of major elements and trace elements,compatible with rare earth elements?hydrocarbon gas comparative analysis,and combining characteristic element combinations and coefficient of variation for each region ? Explore the relationship between various generations of various regions and the mineralization in the area,Concluded as follow:1?Through the analysis of the trend of changes in the concentration of trace elements in the old strata in the three study areas in northern Guangxi,combined with the existence of local ore bodies,it is found that the enrichment of elements in the old strata is closely related to the degree of local mineralization.It can provide reference for prospecting work in the area.2?Judging from the concentration coefficient and coefficient of variation,the northern Guangxi region is still in the initial ore source stage,regional metamorphism is weak,can not reach the level of enrichment layer.It shows that the scale of mineralization in northern Guangxi is relatively small.3?Through the classification and comparison of the trace elements in the geological strata in northern Guangxi,elemental content increased in the order of Mesoproterozoic,Sinian,Cambrian,and Ordovician,this shows that the elemental changes in the stratigraphy gradually enriched over time.4?All three research areas in the northern Guangxi region have similar combinations of elemental characteristics.the main metallogenic elements W,Sn and Bi in the northern Guangxi region all belong to the same group.This shows that the enrichment and migration processes of trace elements in the old strata of the three study areas are similar.5 ? The hydrocarbon components of the three research areas in the northern Guangxi region have similar trends,it shows that in the strata of different regions of the northern Guangxi region,hydrocarbon components may have similar or identical evolutionary processes.6?The content of W,Sn and Bi in the Yuechengling area is significantly higher than that of the Clarke in the strata,and have a better coefficient of variation.This shows that the Yuechengling area has relatively large prospecting potential for the related minerals of W,Sn and Bi.And,by comparing the degree of element enrichment in the three research areas,Yuechengling area is the largest prospecting potential among the three research areas.7?The content of W,Sn and Bi in Maoershan area is slightly higher than that of Clarke in the strata.It is cofficient of variation is generally,and the potential for prospecting is slightly worse than that of Yuecheng Mountain.8?The content of Mo in the Longsheng area is significantly higher than that of the Clarke,and far higher than the other two study areas.Its coefficient of variation is very good.Demonstrates that the molybdenum mineralization potential in Longsheng area is huge.Although the gold content is normal,its coefficient of variation is also good,it explain that gold also has certain mineralization potential.
