Features of fossil soilssols are no longer loose, cracked, and at the land surface. Important differences result from compaction and alteration upon burial which change many of the diagnostic chemical properties of modern soils such as pH, Eh and base saturation. Thus, identification of paleosols can be a problem for both geologists and soil scientists alike.

Soils of other worlds than fiction. Soils on the Moon, for example, are produced principally by micrometeoroid bombardment of those of Venus form by what would be regarded as metamorphic alteration on Earth. These strange landscapes formed by sand blasting and glazing have no clear analogs on Earth.
