Old Rocks,Biased Data:Overcoming Challenges Studying the Geodynamo
Old Rocks Biased Data Overcoming Challenges Studying Geodynamo
2017/3/13
Gleaning data from old rocks may result in bias. Now, geophysicists have a way to improve their methods to overcome challenges in studying the history of the Earth's core and magnetic field that make ...
UW Study:Ancient Rocks of Tetons Formed by Continental Collisions
UW Study Ancient Rocks Tetons Formed Continental Collisions
2016/2/22
University of Wyoming scientists have found evidence of continental collisions in Wyoming’s Teton Range, similar to those in the Himalayas, dating to as early as 2.68 billion years ago.
Orion rocks! Pebble-size particles may jump-start planet formation（图）
rock Pebble-size particles jump-start planet formation
2014/9/1
Astronomers using the National Science Foundation’s (NSF) Green Bank Telescope (GBT) have discovered that filaments of star-forming gas near the Orion Nebula may be brimming with pebble-size particles...
Sorption Characteristics of CO2 on Rocks and Minerals in Storing CO2 Processes
Sorption Characteristics Rocks Minerals Storing CO2 Processes CO2 Geological Storage
2013/3/8
As CO2 is injected into pore spaces of water-filled reservoir rocks, it displaces much of the pore fluids. In short terms (several to tens of years), the greater part of the injected CO2 is predicted ...
Stimulated infrared emission from rocks:assessing a stress indicator
Stimulated infrared emission rocks stress indicator
2009/10/22
To study the effect of stress-activated positive hole (p-hole) charge carriers on the infrared (IR) emission from rocks, we subjected a portion (~10 vol.%) of a large (60×30×7.5 cm3) block of anorthos...
Constraints on the evolutionary history of aluminous mafic rocks in the Ronda peridotite massif (Spain) from trace-element compositions of clinopyroxene and garnet
trace-element clinopyroxene garnet eclogite Ronda granulite
2017/8/9
Multiple trace-element compositions of clinopyroxene and garnet in aluminous mafic layers (±corundum and/or sapphirine) alternating with peridotites from the Ronda massif, Spain, were determined by an...
New Chemical Weathering Indices for Estimating the Mechanical Properties of Rocks: A Case Study from the Kürtün Granodiorite, NE Turkey

2009/7/7
The chemical weathering of rock proceeds by water-rock interaction. During weathering geochemically mobile elements, alkali and alkali-earth elements are easily leached from rocks, leaving the residua...

LAYERED BASIC INTRUSIVE ROCKS OF THE WICHITA MOUNTAINS, S.W. OKLAHOMA
LAYERED BASIC INTRUSIVE ROCKS THE WICHITA MOUNTAINS S.W. OKLAHOMA
2014/4/8
Basic igneous rocks crop out along the axis of the Wichita Mountains of southeastern Oklahoma. Five stratigraphic units have been distinguished on the basis of mineralogical and textural features. The...
