WebDec 11, 2024 · The rift-defining basin margin fault scarps are evident, and rift margin-parallel faults bound intrabasin highs similar to the Central Basin High of the Barmer Basin. Deep seismic profiles of the Gregory Rift Valley document how these intrabasin highs parallel the basin margins and extend for 10's km within the main rift (Simiyu & Keller, 2001 ).
