Syenite body lies within a sequence of Precambrian charnockite, khondalite, basic granulite and quartzite between the towns of Kusarimunda to the west of Kharsali to the east, with Rairakhol lying halfway between.

The syenite complex comprises 2 separate bodies, which form E-W-trending tightly folded structures, within each there are minor folds. In some places the syenites forms mafic-rich lenses, boudins and schlieren.

Important note: This table is based only on rock and mineral ages recorded on mindat.org for this locality and is not necessarily a complete representation of the geochronology, but does give an indication of possible mineralization events relevant to this locality. As more age information is added this table may expand in the future. A break in the table simply indicates a lack of data entered here, not necessarily a break in the geologic sequence. Grey background entries are from different, related, localities.
