Madagascar is the world's 2nd largest island country. Following the prehistoric breakup of the supercontinent Gondwana, Madagascar split from the Indian subcontinent around 88 million years ago, allowing native plants and animals to evolve in relative isolation. Consequently, Madagascar is a biodiversity hotspot ,over 90% of its wildlife is found nowhere else on Earth. Madagascar contains deposits of copper, iron and mangenese ores, graphite, rock salt, pyrites and some minor minerals. By the early 20th century, gold was mined in alluvial deposits spread over the island. At the same time, antimony, copper, iron and tin were thought to be abundant, in addition to asphalt, coal, and petroleum. Currently-agate, quartz, zircon, ilmenite, rutile, labradorite, limestone and marble, cement, graphite, gemstones, nickel and cobalt are also mined. Carnelian Agate is 6-7 on the Mohs scale of hardness. Carnelian is a brownish-red mineral commonly used as a semi-precious gemstone. Similar to carnelian is sard, which is generally harder and darker (the difference is not rigidly defined, and the two names are often used interchangeably. Both carnelian and sard are varieties of the silica mineral chalcedony colored by impurities of iron oxide. The color can vary greatly, ranging from pale orange to an intense almost-black coloration.
