Step 1: Closepet Granite as a geological marker.
The Closepet Granite (also called Closepet batholith) is a large intrusive body in the Dharwar Craton of southern India. It divides the craton into:
- Western Dharwar Craton (WDC) → Contains schist belts like Shimoga and Bababudan.
- Eastern Dharwar Craton (EDC) → Contains schist belts like Kolar and Hutti. Step 2: Location of the schist belts.
- (A) Shimoga: Located in WDC (west of Closepet Granite).
- (B) Kolar: Located in EDC (east of Closepet Granite).
- (C) Bababudan: Located in WDC (west of Closepet Granite).
- (D) Hutti: Located in EDC (east of Closepet Granite). Step 3: Final Answer.
Thus, the schist belts to the east of the Closepet Granite are:
\[
\boxed{\text{Kolar (B) and Hutti (D)}}
\]
