Magmatic water or juvenile water is water that exists within, and in equilibrium with, a magma or water-rich volatile fluids that are derived from a magma. This magmatic water is released to the atmosphere during a volcanic eruption. Magmatic water may also be released as hydrothermal fluids during the late stages of magmatic crystallization or solidification within the Earth's crust. Various theories of ore genesis explain how the various types of mineral deposits form within the Earth's trc-music.com-genesis theories vary depending on the mineral or commodity examined.. Ore-genesis theories generally involve three components: source, transport or conduit, and trap.
From Magmas to Ore Deposits. This collection brings together expertise from the economic geology and igneous petrology communities to track the processes that concentrate volatiles and ore metals from the depths of magmatic systems up through the magmatic-hydrothermal transition and into the ore zone. Many diverse hydrothermal copper deposits containing iron oxides are classified as IOCG deposits. Genetic models need to consider a number of different ore fluid components that may not all have the same source in an individual ore system, and also that economic IOCG deposits may include examples in which key components (especially copper) had different trc-music.com by: 7.
Ore-Bearing Fluids - Their Origin & Migration. The four most important considerations in the formation of ore deposits are: 1. Source and character of ore-bearing fluids. 2. Source of the ore constituents and how they were obtained in solution. 3. Migration of ore-bearing fluids. 4. Manner of deposition. Mineral deposits are therefore commonly clustered in geological provinces (mineral provinces or mineral districts) with some provinces being strongly endowed in particular mineral commodities (Jaireth and Huston, ). An example is the Hamersley Basin in the Pilbara which hosts most of Australia's known iron ore deposits and resources.
