    Abstract: Solid-state reaction is one of some methods to synthesize LiFePO4 powder. However, the post-synthesis crystal structure was found to be imperfect, probably caused by the imperfection of the phospho-olivine structure. This study aimed to investigate the cause of its imperfection. A LiFePO4 powder synthesized via solid-state reaction path was used as... Show More

    Abstract: The relationship between mafic intrusion and gold deposits has always received substantial attention. Based on the petrography, mineralogy, and chronology of two mafic intrusion suites exposed in the Funing area, we found that the mafic intrusion suites have closely relationship with gold mineralization. The 255±4.9-Ma U-Pb age of the early mafic i... Show More
