Abstract

[Abstract] Many of the so-called corestones have been developed from rocky blocks that have been apparently affected by subsurface physicochemical weathering that results in lamination, granulation, and eventually a puggy or stiff clay. The truth is that weathering takes advantage of a previous deformation structure and does not create it by weathering.
[Resumen] Muchas de los llamados bolos residuales se han desarrollado a partir de bloques rocosos que han sido aparentemente afectados por la meteorización fisicoquímica del subsuelo que da lugar a la laminación, la granulación y, finalmente, a una arcilla rugosa o rígida. Lo cierto es que el desgaste aprovecha una estructura de deformación previa y no la crea por el desgaste.
