UW Scientists Gain Supervolcano Insights from Wyoming Granite
UW Scientists Gain Supervolcano Wyoming Granite
2016/6/12
Geophysical monitoring of the ground above active supervolcanoes shows that it rises and falls as magma moves beneath the surface of the Earth. Silica-rich magmas -- like those in the Yellowstone regi...
HYPERSPECTRAL DATA MINING FOR CHARACTERISING GRANITE TYPE URANIUM DEPOSITS IN SOUTH CHINA
Hyper Spectral Data Mining Geology Exploration Identification Integration
2015/12/29
Based on hyper spectral data mining techniques, field spectra data is used to study the diagnosable spectral signatures of uranium mineralization factors in this paper, and the spectral features of pl...
Experimental determination of the coefficient of restitution for meter-scale granite spheres
Asteroids Collisional physics Experimental techniques Planetary formation Planetary rings
2015/12/25
We present results of a series of large-scale experiments to measure the coefficient of restitution for 1-m-diameter rocky bodies in impacts with collision speeds up to 1.5 m s1. The experiments wer...
Measurements Of Granite Joint Surfaces Using Area-Based Matching And A Surface Model
Area-based image matching Surface measurements Granite joint surfaces
2015/1/6
Surface measurements of joints in rock provide an indication of the roughness of the joint plane. With such information,design engineers will be able to classify the joints and estimate their shear st...

Analysis of the Gouldsboro Pluton and the Fehr Granite: Understanding the Scales of Magmatic Processes and Partial Melt Generation from the Deep to Shallow Crust
anatexis bimodalism deep crust granite microprobe migmatites
2014/10/22
The heterogeneity of the continental crust has a first order control on the dynamics of plate tectonic processes and the compositions of the Earth in both time and space. Heterogeneity can be characte...
To most people "geothermal electricity" conjures up images of a steam-enshrouded facility in a place like Iceland where heat from the depths of the Earth comes to the surface. But some geologists – in...

natural stone dimension stone weathering rapakivi granite exploration Finland
2009/10/21
Implications of surface weathering of rapakivi granite outcrops for natural stone evaluation were studied in the Wiborg rapakivi granite batholith in southeastern Finland. The study was performed as f...
The Factors Determining the Position and the Form of Surface Failure in Weathered Granite Slope
exposed rock fragile layer, stability analysis of critical slip surface, strain, surface failure
2009/8/24
To discuss failure phenomena, rainfall and saturation conditions within the soil and soil-surface movement were observed on a steep weathered granite slope containing fragile layers with characteristi...
