Geology of Ethiopia Wikipedia

The geology of Ethiopia includes rocks of the Neoproterozoic East African Orogeny, Jurassic marine sediments and Quaternary rift -related volcanism. Events that greatly shaped Ethiopian geology is the assembly and break-up of Gondwana and the present-day rifting of Africa.

Ethiopia, the land of Oppurtunity for Mining and Petroleum

Ethiopia is well on course to become the first challenger to Australian opals. In 2008, the discovery of spectacular Wollo opals in northern Ethiopia changed the game. This high quality, structurally stable and strikingly beautiful opal was exhibited at the Tucson Gem and Mineral Show in 2010, and Ethiopian opals have been unstoppable ever since.

sedimentary rocks. The stability of minerals and their solubility in water differ, and are controlled by such factors as free energy of weathering reactions, pH, Eh, concentration of different ions in water, and of course by temperature. It is well known, that the stability decreases in the series of rock forming minerals feldspar–amphibole–

Thunderegg Wikipedia

Thunderegg is not synonymous with either geode or agate.A geode is a simple term for a rock with a hollow in it, often with crystal formation/growth. A thunderegg on the other hand is a specific geological structure.A thunderegg may be referred to as a geode if it has a hollow in it, but not all geodes are thundereggs because there are many different ways for a hollow to form.

Mining in Ethiopia Wikipedia

Mining is important to the economy of Ethiopia as a diversification from agriculture.Currently, mining comprises only 1% of GDP. Gold, gemstones (diamonds and sapphires), and industrial minerals are important commodities for the country's export-oriented growth strategy. Tantalum mining has also been profitable. It was reported that in the late 1980s, the mineral industry lacked importance

Opal: The mineral Opal (black, white, fire) information

Opal, being amorphous, is not truly a mineral but a mineraloid. One of the scientifically accepted standards defining a mineral is that a mineral must have a crystal structure,which opal lacks. Despite this, virtually all scientific references, including the acclaimed Dana's System of Mineralogy, categorize Opal together with the true minerals.
