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 was first told in Anglo-Saxon England sometime between the 8th and 11th Centuries, but it's not about that time and place. It's actually set several hundred years earlier, in the 5th or 6th Century. And it doesn't take place in England. Instead, the action happens in the land of the Danes (what is today the nation of Denmark) and the land of the Geats (what is today the nation of Sweden). So, if someone asks you what the setting of Beowulf is, you can tell them that it's 5th or 6th Century Scandinavia.
