Since 2012, some advances have been made through the resource investigation, metallogenesis research, and comprehensive utilizing of lithium deposits in China. Firstly, the progress of lithium exploration has been made in Sichuan, Xinjiang, Qinghai and Jiangxi provinces (autonomous region), Li deposits are not only found within the pegmatite rocks but also within the granitic rocks and sedimentary rocks. Secondly, the methods of geological survey, geochemical and geophysical exploration, remote sensing technology and even drilling technology have been improved, which can be delineating orebodies quickly. Thirdly, the mechanisms of Li mineralization were summarized by analyzing the relationship between the Li contents and kinds of geological phenomena. Based on practie, a new understanding of "'muli-cycle, deep eirculation, integration of internal and extemal" metallogenic mechanism or“MDIE”metallogenic  mechanism for short has been put forwarded further in this paper, and the "five levels + basement ” exploration model has been sucessfully expanded to guide the prospecting work both in the Jiajika and Keeryin pegmatite ore fields in westem Sichuan Province. Besides, new progress has been made in the aspeet of amblygonite deposits of granite-type and hydrothermal type in the Mufushan-Jiuling ore district, which points out a new direction for prospeeting new types of lithium deposits in China.
