『Abstract
A series of 19 paleofacies maps have been generated for given
time intervals between the Late Permian and Holocene to reconstruct
the depositional history of the Arabian Plate. The Succession
of changing lithological sequences is controlled by the interplay
of eustacy and sediment supply with regional and local tectonic
influences. The Mesozoic paleofacies history of the Plate is,
in its central and eastern portion east of Riyadh, strongly influenced
by an older N-trending, horst and graben system that reflects
the grain of the Precambrian Amar Collision and successively younger
structural deformations. The late Paleozoic Hercynian orogenic
event caused block faulting and relative uplift and resulted in
a marked paleorelief. This joined structural pattern dominated
the entire Mesozoic and, to some extent, the Cenozoic facies distribution.
The relationship between producing fields and the paleofacies
maps illustrates the various petroleum systems of particular times
and regions.』
