Determination of the origin of marine diatoms in the Sirius Group glacial deposits from Table Mountain and Mt Feather and the conditions for authigenic chabazite formation in these rocks
Entry ID: K045_1994_1995_NZ_2

Abstract: The age of the Sirius Group glacial deposits in the Transantarctic Mountains are a topic of debate. There are two conflicting models which try to explain the origin of diatoms found in tillite beds in the glacial deposits. One is that the diatoms were from the Antarctic interior and were subsequently eroded and deposited in the tillite. The second model is that the three million year old diatoms ... View entire text
