The special bouguer gravity fields and the deep structure in yinshan-daqingshan mountains;

The feature of deep structure in the area is revealed, and the deep metallogenesis is discused.

By analysing and studying aeromagnetic and gravity anomalies and theirtransformed results,this paper explains the distributing characteristics of deep structures,such as folds and fauIts,granite bodies,the Archean coplex in Qingyuan area and therelations between these deep structures and gold deposits.

A preliminary interpretation on the deep-seated structure of the Longgang compound landmass;

On this basis, the authors focused on the upper mantle lithosphere-asthenosphere structure of eastern China, and concluded the following: (1)seismic tomography images can diotinguish between Mesozoic and Cenozoic deep-seated structures,using di.

Based on the great change of the lithosphere thickness,the geothermal flow and Moho surface,and epigenetic magma structure activities,the sketch map of deep-seated structure of North China is constituted,and the relationship model of Yanshanian upwelling of asthenosphere and lithosphere structural activity is built.

Geophysical characteristics of TanLu fault zone reveals its deep structures.

The paper consists of four parts and the main elements are as follows: Firstly, word, s internal structure motive.

In terms of the characteristic of interior tectonic deformation in the Yangtze plate and the stage of development and evolution in geohistory, its formed mechanism of the intraplate tectonics is treated in this paper, and the conclusion that the downgoing pattern within the lithosphere can be applied to account for its thin-skin tectonic is made out.
