We document a new and unusual occurrence of patterns of protruding spheroidal weathering developed in a dunitic rock of the Pados-Tundra mafic-ultramafic complex of Early Proterozoic age, Kola Peninsula, Russia. It provides an example similar to that

Background Three stages of basalt weathering are known: early or incipient weathering, intermediate weathering and advanced weathering. The Late Oligocene basalt of Gebel Qatrani in Fayum Depression, Egypt, shows signs of early weathering, particular

The aim of this research is to investigate the effect of spheroidal weathering on the physico-mechanical properties of in situ granite boulder in tropical environment. This research was conducted to gain more understanding due to lack of study relate

Granite boulders are characteristic geomorphological structures formed in granitic terrains. Due to their formation process associated with typical spheroidal weathering phenomena, they tend to show more or less ellipsoidal shapes prone to instabilit

Within Santa Margarita Ecological Reserve (SMER), southern California, an ~ 108 Ma diorite-gabbro pluton has weathered spheroidally resulting in the formation of concentric rindlets, i.e., a rindlet zone, around an unaltered ellipsoidal core of the p

A characteristic feature of spheroidal weathering is the rounding of rock block edges, which affects the mechanical stability of slender rock blocks and, consequently, that of slopes prone to toppling. We analysed the influence of this erosion phenom

Boulder fields of granitic rocks have long been believed to be the result of subsurface spheroidal weathering and subsequent erosion of weathering products, such as saprolite, and the exhumation of corestones. However, the morphological characterizat

A paleoweathering saprolite mantle and an associated paleosurface have been recognized into the stratigraphic volcanic succession of the silicic effusive (trachydacite) middle Pleistocene Monte Amiata volcano (Italy). This element has been used for a
