The Ramghat Outcrops

Looking east across the Indus Valley just north of its confluence with the Astor Valley at Ramghat.
Looking East across the Indus valley to the outfalls of the Astor and Ramghat valleys. The Ramghat outcrops lie on the extreme Left (north) of view.

Structures related to the Shabatot Fault rejoin the Indus valley just north of its confluence with the Astor valley at Ramghat.  Exposed along an irrigation canal, these faults provide key kinematic information. Representative plan views of these fault zones (each oriented with North up the screen) are shown below.

Plan view of fault zone cutting metagabbro of the Kohistan arc.  The main fault zones are oriented N-S - along the length of photograph.
Plan view of subsidiary structures within a 1m gouge zone developed in metagabbro of the Kohistan arc.
Plan view of subsidiary structures within a 1m gouge zone developed in metagabbro of the Kohistan arc.  The main fault plane (parallel to long edge of view) is oriented 010-82E, with striations plunge <10 degrees N. The Riedel shear fractures seen here may be used to infer the kinematics in this fault zone.
