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
Bookmark this page Manage My Reading List. Beowulf is the longest and greatest surviving Anglo-Saxon poem. The setting of the epic is the sixth century in what is now known as Denmark and southwestern Sweden. The poem opens with a brief genealogy of the Scylding (Dane) royal dynasty, named after a mythic hero, Scyld Scefing, who reached the tribe's shores as a castaway babe on a ship loaded with treasure. Scyld's funeral is a memorable early ritual in the work, but focus soon shifts to the reign of his great-grandson, Hrothgar, whose successful rule is symbolized by a magnificent central mead-hall called Heorot.
