摘要

Orecretes are defined in the current study as a special type of duricrusts (chemical residues) with heavy metals, accumulated near-surface, but excluding deeper parts that developed under reducing conditions. More than 70 study areas across the globe, some of which containing more than one mineralized site, have been selected during this geomorphological study to cover the various morphoclimatic zones from pole to pole. The supergene mineral assemblages were investigated by means of XRD, SEM-EDS, EMPA (electron microprobe analysis), optical methods and oxygen isotope analysis of carbonates. While these methods remain incomplete, morphoclimatic studies supplemented by data from literature were conducted to determine the physical-chemical regime of orecretes in the course of supergene processes during the most recent parts of the Earth history.
