With the backward method of the stress filed about the conjugate joints and the theory of balanced cross section, the writer analysed the kinematic characteristics and the deformation degree of the Guangping thrust. In accordance with the survey of conjugate joints in the quarts sandstone of Lindi formation in 9 places, we draw a conclusion that the direction of the maximum compressive principal stress is NW-SE; the balanced cross section of the coal district shows that strata shortened at a rate of 38.4%, and that shortening is the result of the thrust moving. Combined with the basic characters of nappe structure and the regional tectonic analysis, the thrust moved from northwest to southeast under the action of the regional compressive stress and result in a large scale of shortening. The above results indicated that the lithosphere of southeastern Fujian, as well as southeastern China experienced strong compressional deformation from the later Mesozoic, and moved with a large scale and a long distance from northwest to southeast.
