First Phosphate believes that Quebec igneous anorthosite phosphate rock is an untapped source of high purity phosphate which ...

IN the middle of the last century much interest was shown in the problem of the genesis of igneous rocks, and especially in the manner of origin of diverse rock-types from a common stock or from a ...

It shows a curious fracture surface due to a heavy gelignite detonation in finely crystalline “trap” rock. So far as I can remember I had seen other examples of this phenomenon, but ...

is supplied from igneous rock from Russia, South Africa, Brazil, and Finland. These igneous phosphate deposits are mostly from the Khibiny Alkalic Igneous Complex (Notholt, 1979) and the Kovdor ...

Researchers have discovered pockets of living microbes within a sealed fracture of a 2-billion-year-old rock from the Bushveld Igneous Complex in South Africa, an area known for its rich ore deposits.

Sources of rare earth elements are frequently associated with volcanoes, dormant or otherwise. Here on Earth, rare-earth ...

Under the influence of geostress, seepage, weathering and artificial disturbance, rock materials inevitably develop defects (fissures, cracks, pores, voids, faults, etc.), which greatly reduce the ...

The rock was excavated from the Bushveld Igneous Complex in South Africa, an area known for its rich ore deposits. This is the oldest example of living microbes being found within ancient rock so ...
