Summary
Abstract: ASTER data and logical operators were successfully used to map phyllic and
argillic-altered rocks in the southeastern part of Afghanistan. Hyperion data
were used to correct ASTER band 5 and ASTER data were georegistered to
orthorectified Landsat TM data. Logical operator algorithms produced argillic
and phyllic byte ASTER images that were converted to vector data and overlain
on ASTER and Landsat TM images.

Alteration and fault patterns indicated that two areas, the Argandab igneous
complex, and the Katawaz basin may contain potential polymetallic vein and
porphyry copper deposits. ASTER alteration mapping in the Chagai Hills
indicates less extensive phyllic and argillic-altered rocks than mapped in the
Argandab igneous complex and the Katawaz basin and patterns of alteration are
inconclusive to predict potential deposit types.
