... to peridotite dissolution and karst-like landforms ( Wirthmann, 1965 ; Trescases, 1973 ; Latham, 1986 ; Genna et al., 2005 ). Weathering of peridotite leaves a considerable residue, which constitutes a thick residual lateritic regolith ( Avias, 1969 ; Trescases, 1973 ; Latham, 1986 ). Infiltration...

A weathering model of the consequences of acidic rains on a continental regolith reveals nearly complete magnetite...

Changing the word soil , in the term soil production function to the term mobile regolith will reduce confusion concerning the actual meanings of these different terms and facilitate a greater degree...

... Abstract The architecture of the critical zone—the distribution of mobile regolith, the thickness of weathered rock, and their characteristics, as well as the topography of the land surface—is shaped by erosion and weathering processes that depend upon both lithology and climate...

... and mark the occurrence of near-surface regolith that is (was) ice rich. The evolution of the Martian landforms has been explained principally by two disparate hypotheses. The first is the “wet hypothesis.” It is derived from the boundary conditions and ice-rich landscape of regions such as the Tuktoyaktuk...

This calculation is based on the delivery rate of 10 Be and its decay rate and suggests that this residual profile...

Paleocollapse structures were formed during an earlier interval of geologic time and are covered by the regolith. Consequently, they are commonly unnoticed until the intensely folded and faulted bedrock...
