Fossiliferous Quaternary marine deposits in the McMurdo Sound Region, Antarctica

Contributions to quaternary geology of Cape Crozier, White Island and Hut Point Peninsula, McMurdo Sound region, Antarctica

“…A few angular basalt boulders up to 30 cm occur on the bench surfaces. Seven erratics of granite were found up to the highest bench (340 m) and Speden and Beck reported fine silty calcareous mudstone erratics (Speden, 1962). There is however a total absence of kenyte.…”

“…In the 1958-59 summer season Speden and Beck reported fossils of the Scallop Hill Formation in moraines to the south of Cape Spencer-Smith (Speden, 1962),…”

Fossil proxies of near-shore sea surface temperatures and seasonality from the late Neogene Antarctic shelf

“…The Scallop Hill Formation (SHF; Figs 2 and 3) in the McMurdo Sound region of the Ross Sea was first defined by Speden (1962) and contains pectinid-bearing deposits (Jonkers 1998). This is the older of two main sedimentary successions in this region (the younger being the Taylor Formation) and consists of tuffaceous sandstone and conglomerate containing Austrochlamys anderssoni (Speden 1962;Jonkers 1998).…”

“…This is the older of two main sedimentary successions in this region (the younger being the Taylor Formation) and consists of tuffaceous sandstone and conglomerate containing Austrochlamys anderssoni (Speden 1962;Jonkers 1998). Balanomorph barnacles belonging to an extant taxon Bathylasma corolliforme (Hoek) (Hexelasma antarcticum Borradaile in Speden [1962]) have also been found (Jonkers 1998). Most exposures of the SHF are not in situ, for example, exposures on Ross and White islands.…”

“…Most exposures of the SHF are not in situ, for example, exposures on Ross and White islands. Speden (1962) suggested it is only in situ at the type locality on Scallop Hill, a trachytic dome on Black…”
