Jan 01, 1977  The influence of the parent rock can also be noticed in Wales, where soils on rhyolite contain 1 5 p.p.m. and those on dolerite 250 p.p.m. Average chromium contents, 100-200 p.p.m., are found in brown forest soils, on basalt, in northeastern China and on andesitic moraine in Scotland.

Basalt - Wikipedia

Basalt (US: / b ə ˈ s ɔː l t, ˈ b eɪ s ɒ l t /, UK: / ˈ b æ s ɔː l t, ˈ b æ s əl t /) is a mafic extrusive igneous rock formed from the rapid cooling of lava rich in magnesium and iron exposed at or very near the surface of a terrestrial planet or a moon. More than 90% of all volcanic rock on Earth is basalt, and the eruption of basalt lava is observed by geologists at about 20 ...

Ellis et al. (2002) measured isotopic compositions of chromium in basalt samples, chromium in reagents, and Cr(VI) in plating baths and in groundwater impacted by plating operations. The rocks, reagents, and plating baths exhibited a narrow range of δ 53 Cr values from −0.07 to 0.36‰.

Ruby Description - GIA

It is arguably one of the most important gems in the colored stone market. In its purest form, the mineral corundum is colorless. Trace elements that become part of the mineral’s crystal structure cause variations in its color. Chromium is the trace element that causes ruby’s red, which ranges from an orangy red to a purplish red.

Mozambique: A Ruby Discovery for the 21st Century

Dec 03, 2014  While rubies owe their red color to chromium, their color is modified by the presence of iron, which reduces the chromium-caused fluorescence. An interesting aspect of rubies from the amphibole-related deposit near Montepuez is their range of iron content, from nearly as low as Burmese marble-type rubies to as high as rubies found in basalt ...

Several other minerals are also typically green, but they aren't widespread and are quite distinctive. These include dioptase, fuchsite, uvarovite, and variscite. You're more likely to find them in rock shops than in the field.

Laterite - Wikipedia

Laterite is both a soil and a rock type rich in iron and aluminum and is commonly considered to have formed in hot and wet tropical areas. Nearly all laterites are of rusty-red coloration, because of high iron oxide content. They develop by intensive and prolonged weathering of the underlying parent rock.Tropical weathering (laterization) is a prolonged process of chemical weathering which ...

An example of this is gabbro. The other type is the extrusive igneous rock that solidifies at or above the earth’s surface. An example is basalt. At times, gabbro contains some rare metals. Gabbros containing the mineral ilmenite are mined to obtain titanium. Some other gabbros are mined to obtain nickel, chromium or platinum.
