阿根廷的冈瓦纳地貌早在20世纪初就被胡安·凯德尔和瓦尔特·彭克以及其他在阿根廷工作的欧洲不同学派的地质学家和博物学家所发现。由于Lester C. King的工作，这些研究在巴西得到了很好的延续，后来Joao Jose Bigarella也进行了大量的研究。然而，在美国地貌学家的影响下，尤其是威廉·索恩伯里（William Thornbury）的影响下，这些概念逐渐从阿根廷地质学界消失了。索恩伯里怀疑这种古老地貌的存在，当时的一个范式是“实际上没有比更新世更古老的地貌”。这些地貌是在非常稳定的构造和气候环境下，在超热带气候条件下发育的深层化学风化过程和在半干旱到湿润环境下发育的山墙作用的结果。
Gondwana Landscapes in Argentina were already identified by Juan Keidel and Walther Penck at the beginnings of the twentieth century, as well as by other geologists and naturalists of the different European schools that worked in this country. These studies were continued at a very good level in Brazil, thanks to the work of Lester C. King, later on intensively followed by Joao Jose Bigarella. However, these concepts gradually disappeared from the Argentine geological scene, dominated by the influence of American geomorphologists, and particularly William Thornbury, who doubted the existence of such ancient landforms, when one of the paradigms of the time was that “practically there is no landscape older than the Pleistocene.” These landforms are the result of the process of both deep chemical weathering, developed in very stable tectonic and climatic environments, under hyper-tropical climates, and pediment processes in semiarid to humid environments.
