During the initial stage of rifting ( ca . 1800 Ma), the Kombolgie sub-basin formed and was filled with a thick succession of mostly clastic sedimentary rocks punctuated by basaltic lava flows and pyroclastics of the Kombolgie Subgroup (lower Katherine River Group; Fig. 3 ; Rawlings 1999...

The Katherine Group is correlated, and shares its depositional style, with the Nelson Head Formation of the Amundsen Basin ( Ielpi and Rainbird, 2016 ; Rainbird et al., 1996a ; Young et al., 1979 ). Specifically, the Eduni, Grafe River...
