Tectonic interpretation in the Modi Khola valley, central Nepal using zirconium-in-rutile Thermometry

摘要: 3. BackgroundZirconium-in-rutile temperature estimates are consistent within uncertainty with estimates from Martin et al.(2010) and Corrie and Kohn (2011)Metamorphism of the Greater and Lesser Himalayan rocks have been studied by Martin et al.(2010) and Corrie and Kohn (2011). Both groups in the Modi Khola valley, central Nepal and used similar thermobarometric methods. The two groups did not produce the same pressure/temperature estimates for the area of study, which has leads to inconsistencies in interpretations of faulting of the region. These discrepancies have implications for the tectonic interpretation of the region, using the zirconium-inrutile thermometer calibrated by Tomkins et al.(2007). Furthermore, the temperature estimates calculated from this thermometer will be used as closure temperatures to compute the relative cooling rates of one side of the fault to the other. A sense of motion across the Bhanuwa fault can then be interpreted.
