Abstract

•Basalt rocks transported or affected by different geologic processes were analyzed.•Most basaltic rocks are disc or sphere shaped due to cooling fractures.•Angularity (roundness) is the most diagnostic morphometric index.•Size frequency distributions are controlled by the initial fracture and fragmentation.•Our results support interpretations of rock populations at different landing sites.
