Dolomite, also known as dolostone and dolomite rock, is a sedimentary rock composed primarily of the mineral dolomite, CaMg(CO 3) 2. Dolomite is found in sedimentary basins worldwide. It is thought to form by the postdepositional alteration of lime mud and limestone by magnesium-rich groundwater.olomite is thought to form when the calcite (CaCO 3) in carbonate mud or limestone is modified by magnesium-rich groundwater. The available magnesium facilitates the conversion of calcite into dolomite (CaMg(CO 3) 2). This chemical change is known as dolomitization.
Beowulf is considered an epic poem in that the main character is a hero who travels great distances to prove his strength at impossible odds against supernatural demons and beasts
The Danes endure constant terror, and their suffering is so extreme that the news of it travels far and wide. At this time, Beowulf, nephew of the Geatish king Hygelac, is the greatest hero in the world. He lives in Geatland, a realm not far from Denmark, in what is now southern Sweden.
