In another example the deeply weathered iron formations of Brazil served to concentrate gold with the limonite of the resulting soils.
The gold of the primary veins was concentrated into the limonites of the deeply weathered rocks.
The soils are developed over a deeply weathered layer of sedimentary rocks consisting of false bedded sandstones which underlies the area.
Deeply weathered chert develops surface pop-outs when used in concrete that undergoes freezing and thawing because of the high porosity of weathered chert.
Deeply weathered profiles are widespread on the continental landmasses between latitudes 35 N and 35 S.
Conditions for the formation of deeply weathered regolith include a topographically moderate relief flat enough to allow leaching of the products of chemical weathering.
The various forms of ironstone include siderite nodules; deeply weathered saprolite, i.e. (laterite); and ooidal ironstone .
In the western side of the cella there are seven detached sculptures and architectural members which have been deeply weathered beaten and eroded.
Oxisols, deeply weathered tropical soils, have a rich fossil record from the Paleoproterozoic onwards.
Evidence for widespread deeply weathered soils in the Paleocene can be seen in abundant oxisols and ultisols in now-heavily glaciated Scotland and Antarctica.
