Secular cooling of Earth as a source of intraplate stress [PDF]
The once popular idea that changes in planetary volume play an important role in terrestrial orogeny and tectonics was generally discarded with the acceptance of plate tectonics.

Design, Implementation, and Evaulation of GIS-Based Learning Materials in an Introductory Geoscience Course [PDF]
, 2002 Little is known about how well GIS-based learning lives up to its potential for improving students' skills in problem solving, analysis, and spatial visualization.

Deep Underground Science and Engineering, EarlyView.This paper investigates the high‐pressure water jet‐pick combined rock‐breaking mode (HPC), which employs high‐pressure water jets to precut grooves on both sides of the picks. The rock‐breaking patterns and performance of the HPC method are obtained, and the auxiliary rock‐breaking mechanism of water jet grooving is revealed.

Uses of volcanic ash beds in geomorphology [PDF]
, 1967 In geomorphology air-fall volcanic ashes possess high value as marker beds. These have proved particularly useful in studies associated with infilling of flood plains, fan building, terrace correlation and chronology, erosion, shoreline and sea level ...

Deep Underground Science and Engineering, EarlyView.Three sets of strength data were selected, including hydrostatic pressure independent within the brittle region (HPI‐B), hydrostatic pressure dependent within the brittle region (HPD‐B), and hydrostatic pressure dependent within the brittle–ductile region (HPD‐BD). For HPI type, the failure envelope within the deviatoric plane remains constant.

Deep Underground Science and Engineering, EarlyView.Abstract As tunnel construction advances in lengths and depths, the construction of tunnels in high geothermal environments has become increasingly common, raising significant fire risks. In this study, a 1:20 scale model tunnel test platform was constructed to investigate the effects of a high geothermal environment on fire behavior in tunnels during ...

A Constrained Tectonics Model for Coronal Heating
, 2011 An analytical and numerical treatment is given of a constrained version of the tectonics model developed by Priest, Heyvaerts, & Title [2002]. We begin with an initial uniform magnetic field ${\bf B} = B_0 \hat{\bf z}$ that is line-tied at the surfaces ...

Deep Underground Science and Engineering, EarlyView.This study highlights that with the static and time‐dependent evolution of slip versus dilation tendency parameter space, structurally controlled deep geothermal systems can be selected within areas of higher permeability and lower seismic hazard. Abstract Faults play a vital role in the Earth's hydraulic system by facilitating fluid flow when dilating
