The main achievements are as follow:①discovering three new minerals in the nature, Pianli-nite, Metakaolinite and Al-Si-Spinel; ②finding new natural pianlinite clay rock, metakaolinite corundum rock and Karst colluvial paligenic bauxite deposit and so on;③putting forward the new concept of "genetic fabrics study of bautife", "burnt deposit" and et al.;④ defining and classifying "genetic types of bauxite in China" and "Clay sedimentary rock";⑤proposing the metallagenetic models of bauxite as "polystage, multiple factor, succesive metallization in differ-ent degree"; ⑥putting forward the heat phase change theories of Kaolinite in nature and their in-dustrial application;⑦through field investigation and research, Locating more than 10 bauxite and clay deposits with reserves over 100, 000,000 tons;⑧ confirming that flint clay is finer and has higher plasticity than soft clay which was predicted 3 years ago;⑨Predicting that sulphide weathered-crust-secondary Karst bauxite deposits occur in Pinguo (Guangxi ), Dabaoshan (Guangdong) and Yunnan; ⑩locating many ball clay deposits in China, thus turning China from import to export.
