SATAM STONE OF INDONESIAN

Satam Stone, Stone Aged Millions of Years There Only in Indonesia There are souvenirs typical of rock that can be brought if they travel to the East Belitung, Bangka Belitung. Satam stone name. Unique stone is black with distinctive veins that supposedly is the result of natural processes on reaction meteor collision with a layer of earth containing high lead millions of years ago, quoted from tektites.co.uk. Occurrence Process: 1) Approximately 780,000 years ago a large asteroid hit the Earth in the South China Sea (probably in the Gulf of Tonkin). This asteroid moving from northwest to southeast and rammed earth with a small angle collisions. 2) At the initial stage of the collision, the kinetic energy of the asteroid that crashed into the earth to melt and deliver momentum to the upper layers of rock in the earth's surface (such as sand and mud) in the collision. 3) the melt layer, consisting of rock melts, leaving the Earth's atmosphere and broke into stone semi-liquid form small dots (globules) called "tektite". These globules form a ball, dumbbells or tears, depending on the speed of rotation that occurs during the formation of tektites stone or stone satam it. 4) Stone Satam spherical, dumbbells and tear cools quickly, so fast that they form a glass (similar to glass, but not pure, like in a bottle of wine or beer modern). 5) Approximately five to six minutes after a collision with an asteroid occurs, the ball is now freezes and becomes a solid start re-entry into the Earth's atmosphere and crashed in the Pacific. 6) For Stone Satam was reentering the Earth's atmosphere at high speed, the friction force was experiencing heat the front of this stone. 7) When the glass is heated with uneven (large temperature difference between the front and rear), it will break. Like pouring boiling water into drinking glasses. 8) The front of Batu Satam will form small fragments. These pieces are also enhanced by the intense pressure due to a slowdown in speed. 9) cosmic speed carried by the momentum of this Satam Stone will eventually decrease and the outbreak of the rock will also be reduced. 10) Because of this Satam stone will fall to the earth by gravity with a more vertical movement. 11) On earth Stone Satam carried by river water and possibly eroded. 2) At the end of Batu Satam be incorporated with sediment deposition are usually also contain lead (eroded from geothermal deposits associated with granite intrusions). 13) In berporositas high piles of sand, fresh water will very slowly carve the stone Satam. Paper-thin cracks (formed because the glass was heated when re-entering the Earth's atmosphere) will be enlarged and formed a small trench-shaped U. Note that this U-shaped trench is formed only in the heated section, the front of Batu Satam (Tektite). The back of this Satam stone remains as the original, spherical.
