Improved dating methods have increased our ability to more precisely determine the timing and durations of glaciations. Utilizing glacial and loess deposits, we have compared glaciations that occurred in North and South America in order to determine if. Noté /5.

The Neogene covers about 20 million years. During this period, mammals and birds continued to evolve into roughly modern forms, while other groups of life remained relatively unchanged. Early hominids, the ancestors of humans, appeared in Africa. The northern Cordilleran volcanic province encompasses a broad area of Neogene to Quaternary volcanism in northwestern British Columbia, the Yukon Territory, and adjacent eastern Alaska.

The intent was to synthesize regional tectonic relations and present new information relative to the magmatic and structural history of the region.

Structural control on the development of these features was provided by a system of Neogene–Quaternary normal and related high-angle oblique slip faults that we call the southern Sierra Nevada fault system (Mahéo et al., ; Saleeby et al., a, a, b; Saleeby and Saleeby, ).Cited by: 6.
