by Robert Schmidt, et al, U.S. Army Combat Studies Institute, 23 May 1984. At dawn on 15 September, 1950, the US X Corps, MG Edward M. Almond commanding, began landing over the difficult and treacherous beaches at Inchon, on the west coast of Korea, more than 150 miles north of the battlefront, and west of Seoul.
Operation Chromite -- the September 1950 amphibious landings at Inchon -- rehabilitated the U.S. military's tarnished post-World War II image. Douglas MacArthur's admirers and detractors alike admitted to his uncanny predilection for victory, never so evident than at his landing at Inchon in the Korean War, code-named 'Operation Chromite.
Chromite - Nom commun. (Minéralogie) Minéral du groupe des spinelles, caractérisé par la formule chimique FeCr2O4, pouvant contenir des traces de magnésium, manganèse, zinc ou aluminium.

Chromium. Chromium (Cr) is a hard, bluish metallic element. The only ore of chromium is the mineral chromite and 99 percent of the world's chromite is found in southern Africa and Zimbabwe. Geologists estimate that there are about 11 billion tons of mineable chromite ore in the world, enough to supply the current demand for hundreds of years.
Chromite is almost twice as dense as a basaltic melt (4,800 kg/m 3 and 2,600 kg/m 3, respectively) and is expected to settle to the chamber floor in a random …
Chromite deposits associated with the ophiolites of the Bou Azzer-El Graara inlier display two types : i) a small podiform type associated with PGE and concentrated in the eastern part of the inlier within the transitional series and cumulates ; ii) a second, large sized type recently discovered in the lower part of the ophiolite, associated with primary …

The Bushveld Igneous Complex (BIC) is known for its laterally extensive platinum group element–bearing layers, the most famous being the Merensky Reef and the UG-2 chromitite in the eastern and western limbs of the complex. In the northern limb, the Platreef mineralization and a thick chromitite seam below it (referred to as the "UG-2 …
Chromite. Chromite is the main source of the metal chromium, a metal used to induce hardness, toughness and chemical resistance in steel. It was named after its chemical composition, chromium oxide. The mineral is brownish to black in colour with a dark brown streak. It has a conchoidal or an uneven fracture as well as no distinct cleavage.

The paper describes disseminated tabular, podiform massive, and transitional chromitite deposits from a mantle section of the Kraka ophiolite massif, South Urals, Russia. The chromitite is hosted by dunite with no correlation between their size and quality and the size of the dunite bodies. Thick dunite bodies mostly host disseminated …
Basic Information. Chromite is a dark grey, metallic, oxide mineral. Due to its metallic luster and occasional magnetic properties, chromite is often mistaken for magnetite. Chromite can often be found in basic igneous rocks, and in the metamorphic and sedimentary rocks created by rocks containing chromite that were affected by weather.
