Through analysis of volcanic tracks, Rice University geophysicists have concluded that hot spots like those that formed the Hawaiian Islands aren’t moving as fast as recently thought.Hot spots are are...
amounts of erupting lava are connected to the destruction of supercontinents and dramatic changes in climate and ecosystems.
New research from UC Davis and Aarhus University in Denmark shows that hig...
New research from UC Davis and Aarhus University in Denmark shows that high mantle temperatures miles beneath the Earth’s surface are essential for generating such large amounts of magma. In fact, the...

Thermal analysis and Hot-stage Raman spectroscopy of the basic copper arsenate mineral
Copper Arsenate Olivenite Cornwallite Cornubite Clinoclase thermal stage Raman spectroscopy Euchroite
2011/11/10
The thermal analysis of euchroite shows two mass loss steps in the temperature range 100–105 °C and 185–205 °C. These mass loss steps are attributed to dehydration and dehydroxylation of the mineral. ...
Thermogravimetric analysis and hot-stage Raman spectroscopy of cubic indium hydroxide
Thermogravimetry Hot-stage Raman spectroscopy Indium hydroxide Indium oxide
2011/11/10
The transition of cubic indium hydroxide to cubic indium oxide has been studied by thermogravimetric analysis complimented with hot-stage Raman spectroscopy. Thermal analysis shows the transition of I...

2017/8/10
The Iwate-Miyagi Nairiku Earthquake in 2008 (M7.2) occurred on June 14th 2008 in the northeastern Japan, Iwate Prefecture. We collected water and gas samples in hot springs from seven localities aroun...
Hydrated lime has been added to hot mix asphalt pavements for over 25 years, improving the mixtures in many ways and increasing the life of highways. Lime contributes to both the mechanical and rheolo...
