Mining. Vietnam's mineral resources, apart from offshore oil and gas, include phosphate, coal, bauxite, base and precious metals, and a variety of industrial minerals.More than 5,000 mineral occurrences have been identified. Five broadly-defined metallogenic epochs have been recognised and, in general, the younger the setting the more abundant the deposits.

In Southern Vietnam. The sapphire deposits of southern Vietnam consist of placers formed by the erosion of alkali-basalt flows (Smith et al. 1995). The sapphires present usually prismatic and pyramidal shapes. The size of the crystals is up to 2-7 mm long, but in Dak Nong, Ngoc Yeu and Da Ban areas they sometimes reach 30-40 mm in diameter.

Locations of Deposits

Deposits are typically found in shales, cherts, limestone, dolomites and sandstone as well as hydrothermal veins or as chemically dissolved phosphate minerals in igneous and metamorphic rocks. One of the world's largest phosphate deposit is the Phosphoria Formation, located in southeast Idaho.

U.S. Granite Production Vs. Imported Granite Countertops

Aug 11, 2014  Chuck Monson, president of Dakota Granite, is in agreement with Swenson. He states that the demand for black granite rose when the U.S. decided to use such slabs imported from India to build the Vietnam Memorial. But again, he was referring to granite to be used for monuments and statues rather than countertops.

Jade - Wikipedia

Jade is an ornamental mineral, mostly known for its green varieties, though it appears naturally in other colors as well, notably yellow and white. Jade can refer to either of two different silicate minerals: nephrite (a silicate of calcium and magnesium in the amphibole group of minerals), or jadeite (a silicate of sodium and aluminium in the pyroxene group of minerals).

Hydrocarbons in the Basement of the South China Sea ...

The paper considers the origin of hydrocarbon accumulations within the Pre-Cenozoic basement of the Vietnam shelf. It is shown that the formation of hydrocarbon deposits is associated with protrusive granite massifs that underwent structural-tectonic reworking at the prototectonic and posthumous (postmagmatic) tectonic stage. Together, the posthumous structure-forming processes led to changes ...

Granite as a reservoir rock? Physics Forums

Jun 21, 2011  You mention Vietnam: here the production is from fractured granite basement. It would be more correct to say the oil has migrated there from source rocks rather from other reservoirs. In other locations the production is from granite wash, the coarse, minimally weathered material eroded from an adjacent granite.

Abstract: SO-CALLED “ION-ADSORPTION TYPE” REE DEPOSITS ...

A significant HREE enrichment was found in the limited area in weathered crust of Nui Phao granite (NPG), which is classified into ilmenite-series granite, near Dai Tu, Thai Nguyen district, northern Vietnam. The authigenic weathered crust, about 10 m in thickness, develops in an area of 20 km 2

It is well documented that this granite belt is one of the most important and largest sources of metallic mineral deposits in the world (Charusiri, 1989). The exploited tin from this region comprise three-quarters of the total world tin production (Nakapadungrat, 1982).
