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.
Dolerite is an igneous rock, it has a medium grain size (1-5mm).
It i made of plagioclse feldspar, olivine and augite. it is hypabyssal. and is a fairly dark rock.
No, it is Igneous
Dolomite is a sedimentary rock.
no
A metamorphic or Igneous rock
No, it's not a sedimentary rock, it is an igneous rock. :)
In order to get an igneous rock from a sedimentary rock, the sedimentary rock must be melted and then that melt must crystallize.
Igneous rock can become sedimentary if it is weathered into sediment and then lithified.
Limestone is a sedimentary rock.
It can be sedimentary when mixed with dolomite or metamorphic when mixed with greenschist A.T. Mineralogist
dolomite is a MINERAL. it is NOT considered a sedimentary rock of any kind. sedimentary rocks are composed of minerals, fragments or particles of other rocks(sedimentary, metamorphic and igneous) and/or organic material, and may or may not contain dolomite. to help you understand: if you think of dolomite as a pure element, then sedimentary rocks are mixtures of different elements
non clastic sedimentary rock :)
It's Sedimentary.
sedimentary
Dolomite (Magnesium Carbonate) is a sedimentary rock.
A metamorphic or Igneous rock
No, it's not a sedimentary rock, it is an igneous rock. :)
becuase the igneous rock cools dowwn and turn into sedimentary rock
In order to get an igneous rock from a sedimentary rock, the sedimentary rock must be melted and then that melt must crystallize.
No. Igneous, sedimentary, and metamorphic rocks are three different categories of rock.
Igneous rock can become sedimentary if it is weathered into sediment and then lithified.
