Subtypes
- (1)
Explosive crater
- (1.1)
Primary impact structure produced by shock waves resulting from a hypervelocity impact. The term “crater” usually refers to smaller (approx. <300 km on the Moon) impact craters (simple crater, complex crater); larger craters, usually with inner and external rings are termed basins.
- (1.2)
Secondary impact crater (secondary crater).
- (1.3)
Volcanic crater (caldera [explosive], pit crater, crater of a composite volcano).
- (1.1)
- (2)
Nonexplosive “crater” (only informally called craters)
- (2.1)
Collapsed tumulus
- (2.2)
Collapsed pingo
- (2.3)
Collapse caldera
- (2.4)
Pit: rimless depression of any origin
- (2.4.1)
Pit crater: generally refers to volcanic, magmatic, or tectonic pits
- (2.4.2)
Penetration pit: the depression produced without shock waves by a low-velocity impact
