nce can be traced around the greater part of Aus-tralia, and is probably due to a eustatic negative movement of the ocean.Kangaroo Island is formed of Cambrian rocks, capped by Tertiaries andbasalt at its east end. The Cambrian rocks continue along the coast east ofBackstairs Passage to the mouth of the Murray River at Port Elliott. Inthe reclaiming, as the result of positive movement of the strand line, of theTertiary basin which extends far inland from this part of the coast, the riversMurray and Darling have become engrafted. From the mouth of the Murray to Cape Northumberland, the coast lineis mostly formed of loose dune sand or consolidated dune sand like that ofCape Northumberland. The dune rock rests either on marine Tertiaries,or on recent alluvials of the Murray basin, or on small inliers of granite. Inland from Cape Northumberland are the recently extinct volcanoes ofMount Schanck, Mount Gambler, etc. From Cape Northumberland to east Geology op the Commonwealth. 247 1 / Xy -

Geology of the Commonwealth. 249 of Warrnambool the coast is similar with occasional outcrops of Tertiary-sediments capped by basaltic lava, until the Otway coast is reached. Thisis formed of freshwater Jurassic strata, in places containing small seams ofcoal. East of the dune rock of Sorrento, the Victorian coast is formed of Ter-tiary rocks and older basalt; then of the G-ippsland coal measures in whichthe claw of a dinosaur and teeth and scales of ceratodus have lately beendiscovered ; then at Cape Liptrap the cliffs are partly Silurian and partlyOrdovician slaty rocks, while at Wilsons Promontory they are of granite.Beyond Corner Inlet there follows to the north-east the long stretch of sandsdeposited in the slack water between the southerly flowing East Australiancurrent, and the current flowing easterly out of Bass Strait. This sandhas engrafted many of the rivers, and formed the Grippsland Lakes. Probablythe reclamation has been helped by a positive movement of the strand line.
