The IgarapÃ© Bahia gold deposit has developed from weathering of a near-vertical hydrothermal Cu (Au) mineralization zone. The unweathered bedrock composed of chlorite schists is mainly metamorphosed basalts, pyroclastic and clastic sedimentary rocks and iron formation.
So what exactly is Bitcoin? Bitcoin is a digital currency and digital payment system that allows people to send and receive Bitcoins â or digital tokens â to anyone, anywhere in the world. It runs on a decentralized network of computers in which all transactions are recorded, verified and updated by technology known as blockchain, which is akin to an online public ledger.
Bitcoin can be used to buy things electronically. In that sense, itâs like conventional dollars, euros, or yen, which are also traded digitally. However, bitcoinâs most important characteristic, and the thing that makes it different to conventional money, is that it is decentralized. No single institution controls the bitcoin network.
