2017/4/10
The last liquids of the lunar magma ocean, known as urKREEP, should be highly enriched in volatiles, such as water,
fluorine, and chlorine. We find chlorine-rich glasses in two pristine KREEP basalts...

2015/9/14
During the period just prior to an earthquake, an electomagnetic emission develops over seismic zones. In this paper, a model of excitation of magnetic fields over zones of volcanic activity is propos...
Noble gas solubility in silicate melts:a review of experimentation and theory, and implications regarding magma degassing processes

2015/9/10
Noble gas solubility in silicate melts and glasses has gained a crucial role in Earth Sciences investigations and
in the studies of non-crystalline materials on a micro to a macro-scale. Due to their...
