Lithostratigraphic division and correlation of the Early Precambrian （Archean－Paleoproterozoic） in North China and age assignment of the lithostratigraphic units;

The different researchers have established and used many different lithostratigraphic units in the west Shandong area disorderly.

The lithostratigraphic unit from old to youth by ascertainment over again as follow: Early Carboniferous Hongliuyuan Formation, Late Carboniferous Shibanshan Formation, Shengliquan Formation and Ganquan Formation, Early Permian Hongliuhe Formation, Middle Permian Luotuogou Formation.

On the lithodemic units of Mesozoic granitoid in east Guangxi --a case from Guposhan-Huashan granitic pluton;

On the rock hierarchical units characteristics and the emplacement mechanism of Silurian granite in the boundary between Hunan and Jiangxi;

Diverse views have long existed about the stratigraphic division and naming,use and age assignment of lithostratigraphic units.

A research into lithodemic unit of the Shimian composite granite mass indicates that according to contact and lithogenetic sequence,8 units (which are incorporated into 3 superunits and 1 superunit assemblage)may be established They form an evolutionary serie

Cut by a thrust,the Jiaduocuo granodiorite tonalite mass occurs as different forms on three nappe sheets The lithodemic units are established On the basis of lithogenetic age and litology,it is divided into four units which are incorporated into one superunit Make an approach to the compositional polarity from which it is concluded that the Garz Litang junction subducted westward

Feasibility and steps for establishment of lithodemic units of granitoids, based on geochemical investigation of stream sediments, are diiscussed and verified in terms of the conception and diivision scheme of lithodemic units.
