Magnetite (± quartz) comblayered textures occur in intrusions intimately associated with orebearing hydrothermal alteration assemblages at the Ridgeway alkalic porphyry AuCu deposit. These magnetiterich textures imply that extremely Ferich magmatic volatiles accumulated within these silicic intrusions.

· Milky quartz is the most common variety of crystalline quartz. The cloudiness of milky quartz comes from microscopic inclusions of fluids, gas or both that have been encased in the crystal from the time the crystal first grew. The inclusions have spoiled the crystal for optical purposes and for the use in jewelry making gemstones. But I still find them beautiful and feel excited when I stumble ...

· The first mineral on our tour was quartz. Most weeks, we''ll only cover one mineral, but there was a very strong push to include magnetite hematite when I polled the blogosphere, so I chose to add both. Both magnetite (Fe3O4) hematite (Fe2O3) are iron oxides. However, the oxidation state of iron.

Magnetite is a rock mineral and one of the main iron ores, with the chemical formula Fe 3 O is one of the oxides of iron, and is ferrimagnetic; it is attracted to a magnet and can be magnetized to become a permanent magnet itself. It is the most magnetic of all the naturallyoccurring minerals on Earth. Naturallymagnetized pieces of magnetite, called lodestone, will attract small pieces ...

The main objective of this study was to coat biogenic and abiogenic magnetite onto quartz sand grains, and compare their performance towards Cr(VI) sorption/removal against suspensions of "free" biogenic and abiogenic magnetite nanoparticles. All materials were characterized in terms of the total amount of iron per gram of sand or total iron per liter of solution (for nanoparticles), Fe(II ...

The first type occurring with quartz gangue in true fissure veins is seldom highly argentiferous, the second type in which kaolinization has taken place is often rich in silver content or highly silverbearing. The character of the rock which the vein traverses is often variable, for the goldbearing veins appear in either igneous or sedimentary rocks, sometimes at the contact zone between ...

Magnetite''s Curie temperature is observed at 850 K. Below the Curie temperature, magnetic moments on tetredral sites, occupied by ferric species, are ferromagnetically aligned while magnetic moments on octedral sites, occupied by ferrous and ferric species, are antiferromagnetic and cancel each other; such combined behavior is termed ferrimagnetic (Cornell and Schwertmann, 1996 ...

Quarzite sind fein bis mittelkörnige metamorphe Gesteine, die mit Quarzgehalten ab 98 Prozent definiert sind. Sie zeichnen sich durch relativ große Beständigkeit gegenüber Umwelteinflüssen aus. Die Bezeichnung Quarzit wird in vielen Fällen nicht ganz zutreffend auf Sandsteine angewendet, die infolge einer Zementation durch Kieselsäure (Verkieselung) ähnlich hart sind wie echter Quarzit.
