摘要：
Based on field relations and petrographic characteristics, alkali feldspar granite in the Gigye area on the western side of the Yangsan fault is classified as an A-type granite. It is mainly composed of quartz, perthitic K-feldspar, and interstitial ferri-annile plus sodic amphiboles such as riebeekite and arfvedsonite, indicating crystallization under hypersolvus, anhydrous conditions. These petro- graphic features are the same as those of the A-type granite in the Gyeongju area on the east side of the Yangsan fault. These distinctive. pre-Eocene granites are separated by about 21.3 km, indicating Cenozoic dextral strike-slip of this amount along the Yangsan fault.
