Geology of the Crust and Mantle, Western United States [PDF]
Science, 1964 Seismic refraction, gravity, phase velocity, and magnetic data, coupled with the geologic record, are all approximately satisfied by the structure shown in Fig. 9. A 20-kilometer crust under the Coast Ranges and Great Valley thickens to more than 30 kilometers under the Sierra Nevada and parts of the Basin and Range province; this whole area is ...

Evidence for Global Synchronism in Mantle Plume Convection, and Possible Significance for Geology
Nature, 1972Volume estimates and age dating of basic, non-orogenic igneous deposits suggest synchronous discharge from many hot spots, identified as mantle plumes. The discharge fluctuations seem to mirror the histories of diverse global geological parameters. Extinction crisis of faunal evolution may reflect trace-element pollution occurring during intervals of ...

Anatomy of a Venusian hot spot: Geology, gravity, and mantle dynamics of Eistla Regio
Journal of Geophysical Research: Planets, 1992Eistla Regio is a series of broad swells, each up to a few thousand kilometers in diameter, in the equatorial highlands of Venus. It is characterized by strong positive free‐air gravity anomalies, shield volcanoes, and rift systems. We present a two‐part study of the western and central portions of this Venusian hot spot.

Earth-Science Reviews, 2013
Abstract The tectonic evolution of the circum-Arctic, including the northern Pacific, Siberian and North American margins, since the Jurassic has been punctuated by the opening and closing of ocean basins, the accretion of autochthonous and allochthonous terranes and associated deformation.

Fractals and Chaos in Geology and Geophysics
, 1992This book introduces the fundamental concepts of fractal geometry and chaotic dynamics. These concepts are then related to a variety of geological and geophysical problems, illustrating just what chaos theory and fractals really tell us and how they can ...

Currents in the mantle and the geology of continents
Tectonophysics, 1991Abstract This paper is the first of a series which have considered the possible effects of currents in the mantle upon continents. It mentions effects of aging in oceans upon the direction of slope of coastal peneplains. When oceans are young the coasts are cliffs from which peneplains dip downward on the inland side.

Carbonates and Evaporites, 2020
The various stages of tectonic activity associated with the Dongwu movement (DM) and the associated sedimentary responses in the Sichuan Basin, Southwest China, have been analyzed and their significance for petroleum geology discussed. The analysis was based on the comprehensive analysis of field outcrops, wells, and seismic data.
