Introduction to Precambrian Weathering and Paleosolsthe atmosphere at the time of their formation and perhaps of the evolution of terrestrial life. This record has not yet been deciphered clearly, since the study of Precambrian paleosols is still in its infancy.

Experimental Procedures to Simulate Weathering Under Atmospheres Which May Have Characterized the Eamonosulfide stability field on appropriate phase diagrams..Deduction of a rate law for the cation dissolution is difficult for our experiments because of the superimposition of reactions involving oxidation of Fe. , precipitation of FeS, and scavenging by precipitates of various solute species.

The Lower Proterozoic Hokkalampi Paleosol in North Karelia, Eastern Finlandous iron, sodium, calcium, and magnesium. In the upper, most thoroughly weathered portions, ferric iron and potassium decrease, in some profiles considerably. Estimates of the extent of weathering (based on the ratio of alumina to more mobile components; the CIA index) are low near the bottom, moder

Paleosol and Ore-Forming Processes in the Elliot Lake District of Canada minerals, i.e., brannerite, uraninite, monazite, and coffinite. Brannerite developed during dia gnesis (the “Pronto reaction”) within the conglomerate and perhaps also by weathering within uppermost soil horizons..Mineralization was related to soil formation in several ways. These include the loss
