This introductory chapter provides a broad overview of magma mixing processes in the volcanic and plutonic environments. The structural, textural and geochemical evidence for magma mixing is briefly discussed, with the aim to provide a general picture about this fundamental, yet relatively poorly known...
Even assuming the Riemann hypothesis, the best upper bound on prime gaps in is , and the best upper bound on semiprime gaps is not significantly better than this – in particular, one cannot reach for any . (There is a remote possibility that an extremely delicate analysis near , together...
tomography, which uses ground vibrations known as seismic waves to create a 3D image of what is happening below Earth’s surface. Using this method, Maguire was able to create an image of the magma chamber framework showing where the magma was located. But these are not crystal-clear images...
With Hyundai’s Genesis luxury brand now firmly established the maker is wasting little time expanding its footprint into the performance realm. Leading the effort is the Genesis GV60 Magma crossover. Previewed by the GV60 Magma concept ahead of the New York auto show, Genesis says the forthco...
That tale is Earth’s history — how the planet went from a rock covered in magma (岩浆) oceans to a green and blue orb (球体) filled with life. Between those inhospitable beginnings and now, continents formed and were tom apart, mountain ranges appeared and disappeared, ice caps spread ...
The ongoing sixth great extinction is referred to as the Anthropocene extinction or the Holocene extinction. There are more species than ever before, despite the fact that just 2% of all species considered to have ever been are believed to exist today. ...
