Marine animals first colonized empty seashells about 470 million years ago Several factors contributed to the spread of this new habitat: increased predation pressure, the rapid diversification of sessile organisms and the enlargement of mollusk shells throughout the Ordovician.

New deep diamond and barium minerals named after UBC researchers Kopylovite was discovered locked inside a ‘deep diamond’ formed about 150 kilometres beneath the Earth’s surface by alumnus Dr. Nester Korolev. Read More: https://lnkd.in/eyHC5jCe

Ancient lost ocean may have built Central Asia’s dinosaur-era mountains Creation of the landmass’s landscape is often attributed to the interplay between tectonic, climatic and mantle-related processes over the last 250 million years.

Sediment core reveals 10,800 years of precipitation history in the Sahara A green Sahara has occurred frequently in recent Earth history, whenever shifts in Earth’s orbital parameters have led to stronger solar radiation in the Northern Hemisphere and, consequently, higher precipitation in northern Africa.

Nepheline Chemical Formula: (Na,K)AlSiO4 Locality: Magnet Cove, Magnet Cove, Ouachita Mountains, Hot Spring County, Arkansas, USA. Name Origin: From the Greek nephele, “cloud,” because it becomes clouded when put in strong acid. Nepheline, is a feldspathoid: a silica-undersaturated aluminosilicate, Na3KAl4Si4O16, that occurs in intrusive and volcanic rocks with low silica, and in their associated pegmatites.

What are the different types of plate tectonic boundaries? Plate boundaries are the edges where two plates meet. Most geologic activities, including volcanoes, earthquakes, and mountain building, take place at plate boundaries. Read More: https://lnkd.in/diyqQ6DR
