Acidification provides the thrust
Munich, Germany (SPX) Jan 30, 2012
Kimberlites are magmatic rocks that form deep in the Earth's interior and are brought to the surface by volcanic eruptions. On their turbulent journey upwards magmas assimilate other types of minerals, collectively referred to as xenoliths (Greek for "foreign rocks"). The xenoliths found in kimberlite include diamonds, and the vast majority of the diamonds mined in the world today is found in kimberlite ores. Exactly how kimberlites acquire the necessary buoyancy for their long ascent through the ... read more
