Abstract

In the Buckeye Range of the Horlick Mountains, 4000 feet of sedimentary rocks nonconformably overlie a granitic basement and underlie a thick diabasic sill. The sedimentary section consists of Devonian sandstone and shale (Horlick formation), Carboniferous (?) tillite (Buckeye formation), Permian (?) platy and carbonaceous shale (Discovery Ridge formation), and Permian arkose, shale, and numerous coal beds (Mount Glossopteris formation). This apparently is the first report of a Paleozoic tillite in Antarctica.

摘要

在霍利克山脉的巴克斯代尔山脉中，4000 英尺厚的沉积岩不整合地覆盖在花岗岩基底之上，并位于一个厚厚的辉绿岩床之下。沉积剖面由泥盆纪砂岩和页岩（霍利克组）、石炭纪（？）冰川泥砾岩（巴克斯代尔组）、二叠纪（？）板状和含碳质页岩（发现岭组）以及二叠纪石英砂岩、页岩和众多煤层（格罗斯特佩特斯山组）组成。这显然是在南极洲首次报道的古生代冰川泥砾岩。
