Title

CORRESPONDING BETWEEN GEOTHERMOMETRY BASED ON MINERAL CHEMISTRY AND DEFORMATION TEMPERATURE FOR MYLONITIZED GRANITE OF NOGHAN BRIDGE (SANANDAJ–SIRJAN ZONE)

Pages

  65-80

Abstract

 Noghan granitoid intrusion is located at the NW of Boin- Miandasht and lies in the Sanandaj-Sirjan structural zone (SSZ). Body shape is a stretched ellipsoid with NW-SE strike. The meta-granite body is extremely deformed and displays mylonitic structure such as lineation and foliation. Mylonitic texture is main texture but also show seriate granular and lipido-granoblastic textures. The main minerals are quartz, K-feldspar, plagioclase, Biotite and muscovite. Chlorite is an accessory mineral. The biotite is magmatic and recrystallized. The chlorites are alteration product. The GEOTHERMOMETRY of biotites and chlorites shows the temperatures of 397-549oC and 231-252oC that show good correlation with microstructure in the rock. Therefore, mantle microstructure including recrystallized subgrains in porphyroclast rims that result to Grain boundary migration and chessboard undulose extinction with fine blocky grains and amoeboid grain in quartz grains show formation temperature close to 500°C. Microstructures such as undulose extinction, pressure solution and in quartz, tensile fracture and bookshelf sliding in feldspar, brittle fractures and displacement of folded pieces in biotite display that temperature is lower than 300°C.
