WebNickel ore refers to the naturally occurring rocks or minerals that contain significant amounts of nickel. Nickel is a chemical element with the symbol Ni and atomic number 28.

Nickel is commonly found in the Earth's crust, but it is typically extracted from its ore … WebThus, coexisting glauconite minerals evolve differently from illite/smectites under diagenetic conditions, as postulated by Velde (1977, p56). Glauconite forms a multi-mineral assemblage only at its upper thermal-stability limit. The limit is 320 °C in hydrothermal experiments but is surely lower in natural rocks (Velde and Odin, 1975).

WebDiagenesis includes the many post-depositional processes that alter a sediment to a rock, a sand to a sandstone. The term diagenesis was coined in 1888 by von Gümbel (p. 334) and has been used in many senses since then.
