Inhalt:
This volume is composed of 10 chapters covering a variety of features including geology, geomorphology, vegetation and soils that characterize the biophysical environment of tepui summits in the western Guayana Highlands, southern Venezuela. The core subject concentrates on the properties, age record, and paleogeographic significance of the peats that have deposited during the Holocene in pseudokarstic depressions on siliceous sedimentary and igneousmetamorphic rocks
