The southern Myanmar tin ore district is an important part of the well-known Southeast Asia tin belt (SATB), and hosts numerous economically important primary tin-tungsten ore deposits. However, the timing of formation of these deposits is unclear due to the scarcity of robust age data. The tectonic setting of tin mineralization in this area also needs to be further …

Feldspar is derived from German "Feld"- field and "Spath" - a rock that does not contain ore. There are two main subgroups that produce gems: the potassium feldspars and the plagioclases (a series from calcium to sodium feldspars).
In addition to hard jade minerals, there are pyroxene, horned diorite, neon stone and sodium feldspar, with few green emerald reaching the gem level. In addition to Myanmar, the world produces China, Guatemala, Japan, the United States, Kazakhstan, Mexico, and Colombia.
The Myanmar EIA Procedure (2015) requires that all new projects or expansions of existing projects must undergo environmental screening to determine the degree and nature of the environmental assessment required. Preparing and Submitting the Project Proposal To initiate the screening and categorization process, the Project Proponent submits a

The chemical composition of feldspars includes alcalic metals, aluminum, silica and oxygen. The general chemical formula is a bit complicated (K,Na) 1-x (Ca,Ba) x (Si 3-x Al 1+x O 8).This complexity is caused by presence …
The feldspar which usually displays the aventurine appearance is oligoclase, though the effect is sometimes seen in orthoclase: hence two kinds of stone are distinguished as oligoclase and orthoclase sunstone. Treatment. In the early 2000s, red or green gemstone resembling sunstone and known as Andesine appeared in the gem market.

yellow feldspar from Malagasy are faceted finest. The best cabochons are cut from Myanmar (Burmese) moonstones, with a display of bright blue reflection, sometimes with a fairly silver to blue color from Sri Lanka.
Sanidine is a polymorph of alkali feldspar stable at yet higher temperature. It may be clear, white, pale-yellow, brick-red, or green, it is generally characterized by cross-hatch twinning that forms as a result of the transformation of monoclinic orthoclase into triclinic microcline. The chemical compound name is potassium aluminium silicate.
