Strain measurement and analysis of tourmalite-quartz enclaves in Yuanbaoshan pluton, northern Guangxi
摘要
Abstract
On the basis of the achievements obtained in geological systemic investigation and analyzing geological characteristics, the authors mainly studied the strain characteristics, genesis and the age of deformation of tourmalite—quartz enclaves. Three—dimensional finite strain measurement and strain analysis of tourmalite-quartz enclaves in Yuanbaoshan pluton were carried out successively. The results show that the three strain patterns of tourmalite-quartz enclaves are plane strain (K=l), flattening strain (0＜K＜1) and contraction strain (1＜K＜∞).The pattern of strain of tourmalite—quartz enclaves in Yuanbaoshan pluton is mainly plane strain,with minor flattening strain and contraction strain.关键词
