Abstract

Similarities of middle anld upper Paleozoic deposits of the Ellsworth fountains with those of the Pensacola, Horlick, and other Transtarctic mountains indicate that all these ranges may have had a related geologic history. A native explanation is now suggested which involves sea-floor spreading atnd anslocationi of the Ellsworth crutstal block from its originilal location adjacent to the East Antarctic Shield. Accordingly, the islands of West Antarctica may differ it origin and the Transantarctic Mountains of East Antarctica may represent one margin of an ancient rift.

摘要

埃尔斯沃思泉地区中上二叠统沉积物与彭萨科拉、霍利克等地的沉积物相似，表明所有这些山脉可能具有相关的地质历史。现在提出了一种本土解释，即埃尔斯沃思克拉通块体从其最初位于东南极盾附近的位置通过海底扩张和迁移，发生了位置的改变。因此，西南极的岛屿可能起源不同，而东南极的横贯南极山脉可能代表一个古老裂谷的一个边缘。
