Astroblemes on trapp rock: Structural features and differences from impact structures on other targets
The paper briefly characterizes the two known terrestrial meteorite craters on trapp rock: (1) Lonar, India (diameter 1,8 km) and Logancha, USSR (diameter 20 km). The features these craters have in common are identified, and their differences from problems on other types of targets are indicated. The probable reasons for these differences are discussed.
