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.

The Beowulf Manuscript. Bookmark this page. We cannot be certain when the Anglo-Saxon poem Beowulf was composed, how it was created, or exactly when it was written down. What we can do is pay attention to top scholars in the field and make some pretty good guesses. The only surviving manuscript of Beowulf is written in Old English (Anglo-Saxon). Rather than being composed at a specific time, the poem probably developed out of various influences, especially folk tales and traditions.
