Abstract

Emerald-bearinz rocks are present near Mingora in Swat State, and Prang Ghar in Mohmand Agency. Rocks containing fuschite in addition to calcite and/or. siderite are perhaps the most favourable for emerald, though some pegmatites and greenshists may also have emerald. The emerald and chrome-mica (fuschite)
probably have some genetic bearing on the chrome-bearing ultramafic intrusions of the two areas.
