Abstract

Abstract

By observing and recording structural feature and deformation of the Ailaoshan Group in the field at Mosha and Jiasa, the stress filed shall be preliminarily divided into two stages: the ductile deformation and brittle deformation. Based on the structural analysis of the stress field for all sorts of small structures, such as schistosity, cleavage, fold, tectonic lens, scratch and the conjugated joints, etc. in the field, it reveals that there exists two tectonic stress fields in the Ailaoshan structural belts, with main stress orientations of NE-SW and NW-SE compressions. The present stress filed sustains the paleotectonic stress filed. Combing with the previous research results, the dynamic sources of two different tectonic stress fields on the Ailaoshan belt are studied briefly, which may be critically linked to its peripheral plates and deep fluid extrusion.
