Microstructure in minerals may have traces of changes in temperature, pressure and strain. The purpose of the present study is to draw out these information from the microstructures. Careful observations and analysis using polarized microscope, SEM and EPMA of the characteristic exsolution texture reveal the history of its proprietary. We will mention the results and discuss the formation process microstructures and the host rock.
