context_page_description: Bulgaria is a country situated in Southeast Europe and occupies the eastern quarter of the Balkan peninsula, being the largest country within its geographic boundaries. It is bordering Romania to the north, Serbia and North Macedonia to the west, Greece and Turkey to the south, and the Black Sea to the east. The northern border with Romania follows the river Danube until the city of Silistra. The land area of Bulgaria is 110,994 square kilometres, slightly larger than that of Iceland or the U.S. state of Tennessee. Considering its relatively small size, Bulgaria has a great variety of topographical features. Even within small parts of the country, the land may be divided into plains, plateaus, hills, mountains, basins, gorges, and deep river valleys. The geographic center of Bulgaria is located in Uzana.
context_section_description: There are approximately 60 types of minerals that are extracted commercially in Bulgaria. The mineral resources are divided into three groups: fossil fuels, metals and industrial minerals.
  The fossil fuels include coal, petroleum and natural gas. Bulgaria possesses significant reserves of coal estimated at 4,8 billion tons. More than 92% of them, or 4,5 billion tons, is lignite, which is the lowest rank of coal due to its relatively low heat content but is widely used for electricity generation. With reserves of 2,856 billion tons Maritsa Iztok, situated in the Upper Thracian Plain, is by far the largest coal basin in the country which powers Maritsa Iztok Complex, the largest energy complex in South-Eastern Europe. Other lignite basins include Sofia valley (reserves of 870 million tons), Elhovo (656 million tons), Lom (277 million tons), Maritsa Zapad (170 million tons). The reserves of sub-bituminous coal are 300 million tons, situated mainly near Bobov Dol, Pernik and Burgas. The recoverable reserves of bituminous coal and anthracite are insignificant – only 10 and 2,5 million tons respectively. However, there is a huge basin of bituminous coal in Southern Dobruja with estimated reserves of over 1 billion tons but its large depth (1370–1950 m) is an obstacle for its commercial exploitation. 
  The Bulgarian exclusive economic zone has a total size of 110,879 km² (42,811 sq mi)}} in the Black Sea. Petroleum and natural gas are found in northern Bulgaria and its EEZ in the Black Sea. Crude oil is extracted in Dolni Dabnik and Gigen in Pleven Province and in Tyulenovo, Dobrich Province. The proven reserves are 20 million tons but there are prospects for new discovering in the EEZ. Gas fields have been discovered off cape Kaliakra (reserves of 3 billion m³), Deventsi (6 billion m³), between Lovech and Etropole (est. 22 billion m³), as well as near Devetaki and Butan. It is estimated that the 14,220 m² Khan Asparukh Block in the northern section of the Bulgarian EEZ has natural gas reserves of 100 billion m³.
  Bulgaria has significant reserves of metal ores, especially copper, zinc and lead, situated mainly in the southern half of the country. The two largest iron ore mines are located in Kremikovtsi near Sofia and Krumovo, Yambol Province with total reserves of 430 million tons. Manganese ore is extracted near Obrochishte in Dobrich Province (reserves of 85 million tons), as well as in the provinces of Sofia and Varna. The reserves of chromium are small and are scattered in the Rhodope Mountains. Bulgaria possesses important reserves of lead and zinc, of them 60% are situated in the southern reaches of the Rhodope Mountains along the border with Greece at Madan, Zlatograd, Madzharovo, Rudozem, Laki, etc. Other mines are located near Ustrem and Gyueshevo. The reserves of copper ore are also significant, situated mainly at Asarel Medet near Panagyurishte, Elatsite mine near Etropole (650 million tons), Elshitsa, Medni Rid near Burgas, etc. There is gold near Tran, Chelopech and Madzharovo, as well as small quantities of platinum, silver, molybdenum, nickel and tungsten.
  Bulgaria is rich in industrial minerals, with 70 types being mined. There are important reserves of rock salt near the town of Provadia (4,4 billion tons). Solnitsata, an ancient town located nearby is believed by Bulgarian archaeologists to be the oldest in Europe and was the site of a salt production facility approximately six millennia ago. The reserves of kaolinite are estimated at 70 million tons, situated mainly in north-eastern Bulgaria – Kaolinovo, Todor Ikonomovo, Senovo and Vetovo. Marble is extracted in the mountainous regions – Pirin, Rhodopes, Strandzha, the western Balkan Mountains. There are important quantities of limestone, gypsum, baryte, perlite, feldspar, granite, etc.
