1Intrusive Contact or Basement? Mapping a Dharwar Schist Belt Margin
A mapping party works a 2 km × 3 km window 12 km southwest of Chitradurga at 1:10,000. The west-to-east traverse crosses chlorite–actinolite schist (metabasalt) with preserved pillow selvedges and graded beds that consistently fine eastwards; then a 200 m wide, coarse pink granite whose sharp contact cuts obliquely across the schistosity at about 40°; then schist again.

A contractor opens a new bench in a Deccan basalt flow near Bagalkot to supply concrete aggregate for a bridge. The flow exposes three zones over 40 m: (1) a lower massive, fine-grained, closely jointed basalt; (2) a middle vesicular basalt in which vesicles up to 8 mm are lined or filled with white zeolite, green clay and, in places, chalcedony; (3) a top red bole and clay-rich weathered basalt.
