Sincura
The Sincura mountain range is in the Bahia state of eastern Brazil. It follows the Paraguaçu river which originates in the Chapada Diamantina National Park, Chapada Diamantina highlands of central Bahia. The Diamond Mines The area is famous for its mines known collectively as the List of diamond mines, Diamond Mines of Sincura. The rivers course followed a rich Vein (geology), vein of diamonds which led to an influx of prospectors. These mines have taken their name from the mountain range to be known cumulatively as the mines of Sincura. "The first individuals who established themselves at the mine of Sincura were mostly convicts and murderers; and their presence was marked by burnings and assassination. The difficulty of procuring sustenance in the country, and the danger incurred by those who came thither to exchange diamonds against the paper money of Brazil, prevented the respectable merchants from engaging in this commerce. But as the population, nevertheless, gradually in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Chapada Diamantina National Park
The Chapada Diamantina National Park (; pt, Parque Nacional da Chapada Diamantina) is a national park in the Chapada Diamantina region of the State of Bahia, Brazil. The terrain is rugged, and mainly covered by flora of the Caatinga biome. Location The park is in the Caatinga biome, and covers . It was created by decree 91.655 of 17 September 1985, and is administered by the Chico Mendes Institute for Biodiversity Conservation.

List Of Diamond Mines
There are a limited number of commercially available diamond mines currently operating in the world, with the 50 largest mines accounting for approximately 90% of global supply. Diamonds are also mined alluvially over disperse areas, where diamonds have been eroded out of the ground, deposited, and concentrated by water or weather action. There is also at least one example of a heritage diamond mine (Crater of Diamonds State Park).

Vein (geology)
In geology, a vein is a distinct sheetlike body of crystallized minerals within a rock. Veins form when mineral constituents carried by an aqueous solution within the rock mass are deposited through precipitation. The hydraulic flow involved is usually due to hydrothermal circulation. Veins are classically thought of as being the ones in the body not the rock veins and arteries planar fractures in rocks, with the crystal growth occurring normal to the walls of the cavity, and the crystal protruding into open space. This certainly is the method for the formation of some veins. However, it is rare in geology for significant open space to remain open in large volumes of rock, especially several kilometers below the surface. Thus, there are two main mechanisms considered likely for the formation of veins: ''open-space filling'' and ''crack-seal growth''. Open space filling Open space filling is the hallmark of epithermal vein systems, such as a stockwork, in greisens or in cert ...

Diamonds
Diamond is a solid form of the element carbon with its atoms arranged in a crystal structure called diamond cubic. Another solid form of carbon known as graphite is the chemically stable form of carbon at room temperature and pressure, but diamond is metastable and converts to it at a negligible rate under those conditions. Diamond has the highest hardness and thermal conductivity of any natural material, properties that are used in major industrial applications such as cutting and polishing tools. They are also the reason that diamond anvil cells can subject materials to pressures found deep in the Earth. Because the arrangement of atoms in diamond is extremely rigid, few types of impurity can contaminate it (two exceptions are boron and nitrogen). Small numbers of defects or impurities (about one per million of lattice atoms) color diamond blue (boron), yellow (nitrogen), brown (defects), green (radiation exposure), purple, pink, orange, or red. Diamond also has a very ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Landforms Of Bahia
A landform is a natural or anthropogenic land feature on the solid surface of the Earth or other planetary body. Landforms together make up a given terrain, and their arrangement in the landscape is known as topography. Landforms include hills, mountains, canyons, and valleys, as well as shoreline features such as bays, peninsulas, and seas, including submerged features such as mid-ocean ridges, volcanoes, and the great ocean basins. Physical characteristics Landforms are categorized by characteristic physical attributes such as elevation, slope, orientation, stratification, rock exposure and soil type. Gross physical features or landforms include intuitive elements such as berms, mounds, hills, ridges, cliffs, valleys, rivers, peninsulas, volcanoes, and numerous other structural and size-scaled (e.g. ponds vs. lakes, hills vs. mountains) elements including various kinds of inland and oceanic waterbodies and sub-surface features. Mountains, hills, plateaux, and plains are the fou ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
