AND SEDIMENTOLOGICAL OBSERVATIONS FROM OMAN AND THEIR
PALAEOGEOLOGICAL IMPLICATIONS

Abstract
Observed exhumed Pleistocene river channel
conglomerates now standing as ridges, and inland sabkha
sedimentological structural phenomena from Oman, are discussed.
Their significance as tools in the interpretation of similar
palaeogeological environments is considered. Correlation with
similar channel fills elsewhere in Arabia and Iran indicates
aggradation as having occurred between 35,000- 7,000 yrs BP and
suggests that this was principally by sustained flow during
pluvial phases accompanying the last global glaciation, (at least
in this part of the Middle East). Elevations of the now inverted
channels above their deflated desert surroundings are used for
calculating deflation rates, and reservoir porosity-permeability
characteristics of similar ancient deposits are considered.
