Dolostone is a rock. Dolomite is the mineral often composing dolostone.
Igneous rock is formed when magma cools and becomes solid.
Extrusive igneous rock such as basalt, rhyolite, pumice, and obsidian.
Cooling and solidifying magma turns into igneous rock.
Dolostone is technically a sedimentary rock, although it's easy to understand why some might consider it to me metamorphic. In a shallow, tropical sea environment, such as the Caribbean Sea, Calcium Carbonate from shells and fish bones creates a layer of sediment, and since there is no sediment input from things like rivers, the Calcium Carbonate layer does not get mixed in with other types of sediment. Over time, this Calcium Carbonate is compressed into Limestone. Water can easily travel through Limestone, and if that water is rich in Magnesium, the Magnesium in the water will start to replace the Calcium in a process called diagenesis. Magnesium is smaller than Calcium, so empty bubbles called vugs form in the rock. Then new rock, which is made of Magnesium, Calcium, and Carbonate, is called Dolostone. Since the rock never changed due to heat and pressure, dolostone is not metamorphic, and since the rock was not made from lava or magma, it is definitely not igneous.
Dolostone is a rock. Dolomite is the mineral often composing dolostone.
Marble is a non-foliated metamorphic rock derived from limestone or dolostone.
Lime stone or dolostone
Dolostone is classified as a sedimentary rock that is primarily composed of the mineral dolomite. It forms through the chemical alteration of limestone by magnesium-rich fluids.
Marble is the metamorphosed result of limestone. Therefore, marble is metamorphic.
Limestone, dolostone and others.
Rock salt and gypsum are not varieties of dolomite.
Limestone and dolostone.
Dolomite is a mineral consisting of calcium magnesium carbonate, while dolostone is a sedimentary rock primarily composed of the mineral dolomite. Dolostone forms when magnesium in seawater replaces some of the calcium in limestone during the rock's formation process.
Igneous rock is formed.
Igneous rock is formed when magma cools and becomes solid.
Obsidian is an igneous rock.
