Abstract
The Asir terrane consists of north-trending belts of variably metamorphosed volcanic, sedimentary, and plutonic rocks that are cut by numerous shear zones (Fig. 1). Previous workers interpreted the shear zones as sutures, structures that modify earlier sutures, or structures that define the margins of tectonic belts across which there are significant lithologic differences and along which there may have been major transposition (Frisch and Al-Shanti, 1977; Greenwood et al., 1982; Brown et al., 1989). SHRIMP data from zircons (Table 1) and sense-of-shear data recently acquired from selected shear zones in the terrane help to constrain the minimum ages and kinematics of these shearing events and lead to an overall model of terrane assembly that is more complex than previously proposed.
