内容記述 | The Main Central Thrust (MCT) zone is one of the most important tectonic zones of the Himalayas along which the inverted metamorphism has been observed. The MCT zone around Annapurna have been surveyed to analyse 3D strain by adopting the least square method (Hayashi, 1994,2001). The problem which is encountered in treating 3D strain analysis, is\nthe precision of strain. The consistent value (c-value) was derived to estimate how the resultant value of strain is consistent with true value (Hayashi, 1995). Setting the c-value properly, invalid samples are excluded from the strain analysis. The paper summarized as its important result that the foliation plane and XY plane are almost parallel together. Although this result has been recognized as a general agreement by many geologists, there has been no direct proof using 3D strain analysis up to now. Shear heating model is considered as the reasonable cause of inverted metamorphism along the MCT from the intermediate intensity of strain. The 3D strain analysis introduced here has benefits that any rock which is composed of grains can be used as marker rock and we can find out such rocks ubiquitously throughout the Himalayas. | |||||||||
