Tin is a chemical element minerals have a name which in Latin means Sn Stannum silvery white metal, with low hardness, density 7.3 g/cm3, and has electrical conductivity and thermal properties of height.
Under normal circumstances (13 - 1600C), a shiny metal and is widely used in the manufacture of household appliances.region has the largest mineral deposit in Indonesia is the Riau Islands.
Riau Islands is part of the largest deposits in Indonesia, the world which stretches from Myanmar to the Riau Islands, continues to Karimata Island to the west of Borneo. Deposition of tin ore in this area is largely a residual residual weathering of sedimentary rocks that originally contained tin ore. Sea in this area is a shallow sea with a depth of about 25 meters, known as the Sunda Shelf region. Sunda Shelf land once believed to consist of 3 major islands in Indonesia, namely Sumatra, Java and Kalimantan, which are now separated because of abuse and regression of sea water. But in reality, only Java and Sumatra, are many roads Mountains and Mount api.Di Kalimantan okay, but the volcano but no longer active and not as an active volcano in Java and Sumatra.

All of that is due process and regression trangresi sea water before, lasted a long prose (in a geological time scale) which then undergo a process of inundation of sea water. Because this mineral is the result of minerals from magma intrusion, not mineral rarely found in areas of Java and Sumatra.
Usefulness of tin minerals, among others:
1. As the material appliances.
2 furniture. Make solder
3. Plate
4 tin. Metal coating
5. Metal decoration
6. Used in Chemical Industry and war equipment
So Tin minerals are minerals that formed due to intrusion of magma through the cracks or burly-burly of granite so that the granite magma and also because of the influence of minerals - mineral-related or mixed into the magma chamber itself.
