Doba Basin, Chad, is situated within the Central African rift system and contains up to 13 km (8 mi) of Cretaceous alluvial and lacustrine deposits. The complex climatic and tectonic evolution of the region, spanning the early to late Cretaceous is uniquely recorded in the stratigraphic architecture. In this chapter, we present a model of alluvial and lacustrine fill, which invokes high-frequency climatic fluctuations superimposed on longer term climatic cycles and variable accommodation produced by extensional tectonic processes.
Upper Cretaceous (Cenomanian-Coniacian) Doba Basin stratal successions are interpreted to represent alluvial depositional systems that systematically varied along their longitudinal depositional...

Lacustrine Sandstone Reservoirs and Hydrocarbon Systems
Many publications on lacustrine systems concentrate on reconstructing paleo-environments, deciphering paleoclimate or estimating hydrocarbon source potential. This is the first memoir to give attention to describing the occurrence, distribution and character of sandstones in various lake settings. the volume is the outcome of a Hedberg Conference held in Baku, Azerbaijan in 2004. The memoir is divided into four sections beginning with a global overview, and followed by two sections covering lacustrine systems in compressional and extensional regimes. The volume concludes with a series of papers on modern lake regimes.
