Soil geochemical characteristics and lithium ore prospecting direction in the Guanyinqiao area of western Sichuan
Guanyinqiao is located in Jinchuan County,Aba Prefecture,Sichuan Province,and is located in the northwest of the Kelin key exploration area.The lithium deposits in the area are mainly spodumene-based granite pegmatite veins,and the wall rock alteration is mainly andalusite,cordierization and biotitization,etc.At present,the degree of research on geochemical anomalies and ore prospecting directions in this area is relatively low.In order to study the soil geochemical characteristics of the Guanyinqiao area and further guide mineral prospecting,a 1∶10000 soil geochemical measurement was carried out in the Guanyinqiao area,and 11 elements including Li,Be,Nb,Ta,and Th were selected for testing.It was found that the area elements that are indicative of Li ore include Be,Nb,Ta,etc.,which are negatively correlated with Th.A total of 3 soil geochemical combina-tion anomalies were delineated this time.The anomalies showed good concentration zoning,obvious concentration centers and abnormal peaks,good anomaly matching of major mineralization elements,and superior geological mineralization conditions.Combining the geological characteristics of lithium ore and verification of HT2 anomalies,a new medium-sized potential lithium deposit was discovered,making new progress in ore prospecting.Through comprehensive comparison,it is speculated that medium-sized and above-scale lithium deposits are also expected to be found in the HT1 combination abnormal zone,which points out the direction for the next step of lithium ore prospecting and exploration in the area.
