南漳县西部梁山组富锂黏土岩物源区特征
Source Area Characteristics of Lithium Rich Clay Rocks in the Liangshan Formation of Western Nanzhang County
摘要
Abstract
With the vigorous development of the photovoltaic industry and the new energy vehicle industry,the demand for lithium resources at home and abroad continues to increase,and clay type lithium mines have gradually become the focus of mineral exploration.According to geological surveys,there is an abnormal enrichment of lithium in the clay rocks of the Liangshan Formation in the western Nanzhang county,which has the potential to form independent lithium deposits,however,research on the source characteristics,sedimentary environment,and mineralization laws of the lithium rich clay rocks of the Liangshan Formation is still blank.Therefore,it is necessary to study the source characteristics of lithium rich clay rocks in the Liangshan Formation in the western Nanzhang county,in order to further reveal the geological characteristics of its source area and provide effective guidance for subsequent mineral exploration work.According to measurements,the Al2O3/TiO2 ratio of the lithium rich clay rock samples from the Liangshan Formation in the western Nanzhang county ranges from 14.45 to 37.69,with an average value of 27.68;the K2O/Al2O3 ratio ranges from 0.001 7 to 0.020 6,with an average value of 0.009 8;the Cr/Zr ratio ranges from 0.144 9 to 0.351 9,with an average value of 0.277 5.The results indicate that the clay source area is mainly composed of felsic rocks.In the La/Sc-Th/Co diagram and Zr-TiO2 diagram,all sample points are located in the source region of feldspar,indicating the singularity of the source.The Chemical Index of Alteration(CIA)and Chemical Index of Weathering(CIW)of most samples are above 90,indicating that the source rock has undergone strong chemical weathering.关键词
