What kind of rock is dolostone, commonly found in Niagara Cave?

• A. A metamorphic rock
• B. A volcanic rock
• C. A sedimentary rock composed mainly of dolomite
• D. An igneous rock

Answer: (C)

Dolostone is classified as a sedimentary rock composed primarily of dolomite, which is a mineral made up of calcium magnesium carbonate. This formation typically occurs through the alteration of limestone, where magnesium-rich waters react with the calcite in limestone, resulting in the formation of dolostone. Sedimentary rocks like dolostone often form from the accumulation and compression of mineral and organic particles over time, indicating a history of deposition in various environmental settings, such as ancient seabeds. The presence of dolostone in Niagara Cave is significant because it highlights the geological processes that have taken place in the area, including the prehistoric conditions under which these deposits formed. Understanding dolostone as a sedimentary rock also aids in appreciating the types of formations and features that visitors may observe while touring Niagara Cave, including the intricate patterns and structures formed by mineral deposition in a cave environment.
