| Abstract: | The recent(from 2001 to 2005) gravity and local GPS strain data in the middle region of Shaanxi are analysed.These data show that:1)both gravity and strain fields were coincidently rising in the west and the south,dropping in the east and the north;2)the gravity and maximal shear strain values along the arcuate fault belt of south-western Ordos were high and positive,and controlled by compress field,but the gravity value was negative and the maximum shear strain value was high in the middle-eastern area,especially,near the Kouzhen-Guanshan faults,where it was controlled by extensional plane strain field. |
