Stratigraphic and sedimentological data from New South Wales and Queensland, eastern Australia, indicate that the late Paleozoic ice age consisted of at least eight discrete glacial intervals (each 1–8 m.y. in duration) separated by nonglacial intervals of comparable duration. These events spanned an interval from the mid-Carboniferous (ca. 327 Ma) to the early Late Permian (ca. 260 Ma), and they illustrate a pattern of increasing climatic austerity and increasingly widespread glacial ice from initial onset until an acme in the Early Permian, followed by an opposite trend toward the final demise of glaciation in the Late Permian.
Glacial facies are...
