Veins Geology Encyclopedia

Veins Geology - Encyclopedia. VEINS in geology masses of rock which occupy fissures in other rocks. They may have originated in many different ways and present a great variety of forms and structures. We may classify them in three groups i. veins of igneous rock ii. of sedimentary and iii. of minerals deposited by water or by gases.

Magmatic stoping geology Britannica

Other articles where Magmatic stoping is discussed Reginald Aldworth Daly independently developed the theory of magmatic stoping whereby molten magma rises through the Earths crust and shatters but does not melt the surrounding rocks. The rocks being denser than the magma then sink making room for the magma to rise. This theory was instrumental in explaining the structure of many

Jul 01 2015 The flotation of magnetite has been suggested for other magmatic systems. A single bubble observed in the Bishop Tuff was coated in small magnetite crystals Gualda and Anderson 2007 interpreted as reflecting heterogeneous nucleation of bubbles on magnetite as commonly observed in experiments Gardner and Denis 2004.Bubbles and magnetites were coupled in mafic enclaves

Ore deposits related to magmatic activity

Ore Deposits Related to Magmatic Activity. Certain accessory or uncommon constituents of magmas become enriched into bodies of sufficient size and richness to constitute valuable mineral deposits eg. Chromite and platinum. Magmatic ore deposits are characterized by their close relationship with intermediate or deep seated intrusive igneous rocks.

Vertically extensive and unstable magmatic systems A

Mar 24 2017 Shallow magma chambers either erupt as volcanoes or solidify as intrusive magma bodies. These magma bodies are traditionally considered to be long-lived and dominated by melt. Cashman et al. review the evidence that shallow magma chambers are actually assembled quickly from much larger crystal-rich transcrustal magmatic systems. This paradigm helps explain many

Mineral deposit Immiscible melts Britannica

Immiscible sulfide drops can become segregated and form immiscible magma layers in a magma chamber in the same way that cumulus layers form then when layers of sulfide magma cool and crystallize the result is a deposit of ore minerals of copper nickel and platinum-group metals in a gangue of an iron sulfide mineral.
