Delta bathymetry, seismic data and near-surface sediment sampling on modern deltas with
significant wave, tidal or marine current influence betray a double clinoform architecture with …

The extinct giant shark Otodus megalodon is the last member of the predatory megatoothed
lineage and is reported from Neogene sediments from nearly all continents. The timing of …

Stratigraphy is defined as the study of layered rocks. In the context of sedimentary geology in
general, and of this book in particular, stratigraphy is the discipline that pulls everything …

It has long been understood that the stratigraphic record is fragmentary. Barrell was the first
to clearly understand the importance of accommodation, and the episodic way in which …

For almost a century the Baja California peninsula (Peninsula), Gulf of California (Gulf), and
broader Sonoran Desert region (figure 1) have drawn geologists and biologists alike to …

The energy transition towards a more sustainable and renewable future is a pivotal global
endeavor. Central to this shift for the United States is the critical role of domestically sourced …

Paleozoic siliciclastic rocks from the Schwarzburg area of the German Saxo-Thuringian
Zone encompass a 250 Ma peri-Gondwanan sedimentary record from the Cadomian to the …

We applied multiple geochemical tracers (87Sr/86Sr,[Sr], δ13C, and δ18O) to waters and
carbonates of the lower Colorado River system to evaluate its paleohydrology over the past …

Sanidine dating and magnetostratigraphy constrain the timing of integration of the lower
Colorado River (southwestern United States and northern Mexico) with the evolving Gulf of …

Siliciclastic muds (clay-and silt-sized sediment) concentrate physical and chemical
weathering products. However, both rock composition and climate can affect the mineralogy …
