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
Beowulf is the oldest epic poem in the English language. It was written in Old English (Anglo-Saxon) sometime in the 11th century. The actual story originated between 680 and 839 A.D., when it was told orally and passed down. The plot is set in Sweden in the 6th century. What we don't know is who wrote it and how much is actually based on historical facts. The original poem includes alliterative verse, the repetition of initial sounds of words, and kennings, compound metaphors, but did not rhyme. Themes in Beowulf include Good vs. Evil, Religion (there are some Christian and Pagan references), fate, and others. In the story, Hrothgar, king of the Danes, builds an enormous hall called Heorot, the largest in the world.
