| Potassium salt deposit is a typical sedimentary deposit in Bagan area of Vientiane City,Laos,According to the relevant survey results,the research area is listed as a secondary prospecting area,which has a good prospect of mineral prospecting.Therefore,this paper is based on the census project,By means of field surveys,boreholes and grooves,The geological characteristics of the deposit,the geological characteristics of the ore body and the characteristics of stratigraphic mineralization are studied in detail.The paper also discusses the metallogenic law,which provides important basis for the study of the formation mechanism of salt structure and the metallogenic law of potassium salt deposit in Bagan area.Main knowledge gained:?1?The mineral-bearing strata in the research area are the ancient and recent Tatung Formation?E1tg?.Potassium salt ore is produced in the ointment salt section and the ointment salt section under the Tagong Formation.The main orebody in the lower anointing salt section is in the deposit layer,followed by the middle anointing salt section;Gray,dark gray,thin-thick layer of salt-bearing mudstone is the marker layer for the coming mine;?2?The types of ore in the mining area are mainly opticalite ore,opticalite ore is mainly opticalhalogen,potassium stone salt is less,and the total?associated?mineral is Stone salt and gypsum;?3?I mineral body From the plane point of view,it is similar to an ellipse.The long axis is from the South West to the North East.From the exposed strata section,it is analyzed to belong to a gentle salt anticline,and the No.1 salt anticline axis faces northwestwards.The potassium salt ore body gradually thinned from the nucleus to the wings and eventually disappeared.?4?The lithologic distribution on the plane reflects the typical characteristics of bovine eye deposition.In the center of the salt basin,it is the center of potassium salt ore and stone salt deposition,while the edges are mostly gypsum and clastic mixed rock salt rocks. |
