Based on the survey , analysis and contrast of 19 Cambrian sections in southeast margin of Yangtze plate, it is considered that the black carbonaceous shale, silicic shale, silicic belt and conglomeration and phosphorus bed & conglomeration are formed by the upwelling in Palaeotethys in passive continental margin.

Late Paleozoic basic magmatism from SW Yangtze Massif and evolution of the Paleo- Tethyan Ocean;

Yangtze massif is known for the leading phosphogenetic area in China, especially in the times of Doushantuo and Meishucun ages when the sedimentary phosphorite account for 85% of the state's total phosphorus resources.

A synthetical study of geomorphology, Quaternary, isotopic geochronology, tectonics and sedimentology shows that the orogenic belt in the western margin of Yangtze massif has been mainly risen since Cenozoic, especially the Quaternary, with a rising height of 2, 000-4, 000 m.

Geological feature and structure environment of micro-fine disseminated gold deposit in the southwest edge of Yangtze block;

Some geochemi-cal characteristics of the same kind of rocks related to Cu-Au mineralizations are listed here, and these rocks are from the east Yangtze Block, the Tibet Plateau and the north Xinjiang.

A total of 316 oriented core samples collected from the Devonian-Carboniferous carbonate strata from the southern Yangtze block in the southern Guizhou Province were subjected to stepwise demagnetization.

Evolution of Marine Basins and Exploration Direction Estimation of Oil and Gas in Lower Yangtze Areas;

Lower Yangtze area is one of the prior marine blocks of petroleum exploration in South China.

Lower Yangtze area is a superimposition basin modified by multiple tectonic movement.
