Dunes are present in nearly all fluvial channels and are vital in predicting flow resistance,
sediment transport, and deposition within many rivers. Progress in understanding the fluid …

Extensive evidence of landform-scale martian geomorphic changes has been acquired in
the last decade, and the number and range of examples of surface activity have increased …

The study and interpretation of the textures, sedimentary structures, fossils, and lithologic
associations of sedimentary rocks on the scale of an outcrop, well section, or small segment …

Now enhanced with colour photographs and illustrations, this thoroughly revised fourth
edition of Sedimentary Structures enhances its status as a major textbook in geology. Since …

Nonrenewable energy resources, comprising fossil fuels and uranium, are not ran domly
distributed within the Earth's crust. They formed in response to a complex array of geologic …

Reconstruction of the palaeoenvironmental context of Martian sedimentary rocks is central to
studies of ancient Martian habitability and regional palaeoclimate history. This paper reports …

Outcrop exposures of sedimentary rocks at the Opportunity landing site (Meridiani Planum)
form a set of genetically related strata defined here informally as the Burns formation. This …

Publisher Summary This chapter examines the morphology, process-response
relationships, and internal structures of two larger-scale groups of bed features and dunes …

A simple computer-simulation algorithm for the transport of sand by wind produces forms
resembling barchan, crescentic ridge, linear, and star natural dune classes. Sand is moved …

Decades of research using remotely sensed data have extracted evidence for the presence
of an ocean in the northern lowlands of Mars in the Hesperian (∼ 3.3 Ga), but these claims …
