Platinum group

There are three geological environments in Albrooterozoak rocks in the Arabian Shield compatible with occurrences containing platinum group metals, namely:
A) complexes of ultramafic stratigraphy and ultramafic rocks.
B) chromite lenses mass of Alpine type complexes.
C) deposits shrines derived from a former types.
The studies summarized metals platinum group are very limited and the best known is the study condensed and the public by the French mission BRGM at the north-west of the Arabian Shield in 1984 where there Makdan two co-chairs of ultramafic rocks and ultramafic to my Valley Kamal, as well as Mount surprisingly, has undergone two signatories of the study referred to The study also has chromite lenses mass in the regions of the Valley of shops and Mount wasq addition to collecting samples from the two others.
1) Wadi Kamal
It has been identified many of the complexes Layering benchtop Maver in the Arabian Shield, and most important of those in the valley of perfection.

Sapphire)) AND Topaz AND Ruby

Yellow sapphire or topaz consists of Moonstone, fluorine (Al2SiO4 (F, OH 2)). Topaz different colors and the most famous golden color oblique to the color orange, yellow, dark brown to yellowish oblique, pink, red may be colorless. And up hardness minerals in topaz table degrees to eight degrees where raking quartz (quartz), but he can not scratch diamond and sapphire red.

Exhale as is the case it consists in rubies of aluminum oxide (α-Al2O3) Restaurant iron and titanium instead of chrome. Savir popular color is blue, but may be other colors and depending on the type of impurities contained in the degree of hardness may reach nine degrees.

Red Sapphire consists of aluminum oxide or corundum (corundum) Restaurant chromium atoms (Al2O3: Cr) which give it a red color and bright sapphire comes after the diamond in terms of hardness, where the nine degrees. Sapphire color ranges from bright red color (pink) to dark red or the color of blood (blood-red).

Derived from the Greek word meaning green, because the existence of the green to the permeation of copper in crystals.

Bright green color is caused by a distinguished presence in the vicinity of almost deposition of copper, malachite and acts as a guide to the presence of copper ore in the area. Glitter malachite glass or silk or dark, and Gakth light green brocaded and broken, and cruelty 4 and qualitative weight 4, and his regime mono crystalline Almild.

Polished raw malachite way oval shape, which shows the beauty of crystals, extracted malachite often from inside the copper mines in the form of sharp crystals does not exceed a few centimeters in length, width of a few millimeters, or in the form of a small component blocks of very fine fibers, and according to different concentrations of these fibers, contrasting green color becomes dark or opening.

There malachite in Zaire, Zambia and Zimbabwe, Africa, Russia, Wales, Europe and Australia.

Using malachite Khjarh ornamental and stone cream and made him bracelets, contracts and rings and clamps, preferably gems makers frames of silver wire placed around the headstones, malachite, to give them more beauty, as well as small statues and flower pots and cans ornaments, as well as use it to decorate palaces, private palaces Russia's tsars, has been used as the ancient painters powder malachite green as a color in their paintings, and is available and widespread than Alozoraat which is commonly found with him.
