Pure and Applied Geophysics, 1998
A brief outline is given on experimental studies carried out in the Minnesota Mineral and Rock Physics Laboratory of microstructural evolution and rheology of mantle mineral aggregates or their analogues, using a simple shear deformation geometry.

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.

Earthquake calamity warning from space station: orbital dynamics coupling geology mantle convection
SPIE Proceedings, 2009It is not surprising that the earthquakes happened among clashing tectonic plate boundaries where numerous earthquake stations exist. Then, why do we need more? The significance of Sichuan and Tongshan earthquakes of China is a wakeup call that major earthquakes of logarithmic Richter scales beyond 7 could happen exactly within a single tectonic ...

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.

SEISMIC ANISOTROPY BENEATH THE CONTINENTS: Probing the Depths of Geology
, 1996Seismic anisotropy beneath continents is analyzed from shear-wave splitting recorded at more than 300 continental seismic stations. Anisotropy is found to be a ubiquitous property that is due to mantle deformation from past and present orogenic activity.
