· Monozite is one of the mineral resources that contain REE and it is found in mineral sand deposits (about percent) in Sri Lanka. Monozite is also found in many places in Matara, Nuwaraeliya, Teldeniya, Balangoda, etc. Thorianite and thorite have been reported from Bambarabotuwa (in Sabaragamuwa), in Galle District and in Balangoda.
· Since it is the third hardest mineral on the Mohs scale, it can scratch almost every other mineral. Pure corundum is transparent; however, it can have different colors when impurities are present. Different colored corundum crystals have different names: the red colored corundum is known as ruby, while pink-orange is called padparadscha, and all others are
Talc deposits are associated with the white, siliceous, dolomitic Murphy Marble in Cherokee and Swain counties. These deposits were mined as early as 1859 but are currently inactive. Heavy minerals - Deposits of heavy minerals, including ilmenite, rutile, and zircon have been discovered in the upper Coastal Plain of North Carolina.
· The chemical name for the substance of quartz is silica; and any mineral that is composed in part of silica is a silicate. In the Classification of Silicate Minerals and the study of minerals and rocks, silica is called an acid; in silicates, the substances other than silica are called bases, for example, lime, potash, and soda. When giving the full name of a silicate the
· Dolomite, also known as calcium magnesium carbonate, is a non-metallic material used in manufacturing bricks, mortar, cement, concrete, plastics, paving materials, and other construction materials.
Ores can be said to be those minerals from which metal can be economically and easily extracted. Metals are not always found in the free state. Metals like Potassium, Sodium, Calcium, Magnesium, etc are found in a combined state.
· The most important Cu-Pb-Zn deposits (marked in the map) are hosted in so called "Shisto-Calcaire Group" build mostly by carbonates such as limestones, dolomites and marls. Map by S. Olson. Niari basin is built by Neoproterozoic (+/- 600-700 Mya old) sedimentary rocks, such as limestone (on the photo with karstic formations), sandstones, shales etc.
Dolomite is a very common mineral, and is known for its saddle-shaped curved crystal aggregates.

· The major minerals found in this deposit are Ilmenite and Rutile. Other associated minerals are Zircon, Monazite, Garnet, Sillimanite, and few other heavy minerals. This is the only commercially exploited mineral sands deposit in Sri Lanka while several other mineral sand deposits are available as beach mineral sand deposits.
While N can be provided from the air by biological nitrogen fixation (BNF) and organic sources, P and K and all other plant nutrients must be provided from rocks and minerals. Considerable amount of research has been conducted in the last few decades to find alternative local PR resources to meet the soils requirements for P.
Other Chinese production comes from deposits in Sichuan and Shangdong provinces. Discovered in 1927, Bayan Obo was initially considered to be an iron ore deposit. However, nine years later its rare-earth potential was recognized, with niobium being added to its list of resources in the late 1950s.
Cinnabar (/ ˈ s ɪ n ə ˌ b ɑːr /) or cinnabarite (/ s ɪ n ə ˈ b ɑːr aɪ t /), from the Ancient Greek: κιννάβαρι (kinnabari), is the bright scarlet to brick-red form of mercury(II) sulfide (HgS). It is the most common source ore for refining elemental mercury, and is the historic source for the brilliant red or scarlet pigment termed vermilion and associated red mercury pigments.
