Marble – KLZ Stone Supply, Inc. | Granite, Marble ...

Marble is a non-foliated metamorphic rock composed of recrystallized carbonate minerals, most commonly calcite or dolomite. Geologists use the term "marble" to refer to metamorphosed limestone; however, stonemasons use the term more broadly to encompass unmetamorphosed limestone. Marble is commonly used for sculpture and as a building material.

Dolomite Rock

Dolomite or dolostone is a carbonate sedimentary rock containing more than 50% by weight of the mineral dolomite.Dolomite rock may contain calcite, but the content of calcite should not exceed 10% of the calcite-dolomite pair''s content 3.. Dolomite in Northern Norway (Trollholmsund) which was once chalk, but the original material has been replaced with dolomite.

Marble is a metamorphic rock resulting from metamorphism of sedimentary carbonate rocks, either dolostone or limestone. This metamorphic process causes a total recrystallization of actual rock into an interlocking mosaic of calcite and dolomite crystals. The temperatures and pressure required to shape marble normally destroy any fossils and ...

Dolomite

 · Dolomite, also known as dolostone and dolomitic marble, is a sedimentary rock composed primarily of the mineral dolomite. It is thought to form by the post-depositional alteration of lime mud and limestone by magnesium-rich groundwater. The trend for white and gray lends itself to the typical Dolomite colors. The Dolomites are slightly harder than average marble

Is it Calcite or Dolomite?

Midwestern limestone is a tan or buff color, and is also commonly used in home construction. When limestone has few impurities, it is snow-white, or nearly so. When subjected to heat and pressure, limestone recrystallizes enough to form a harder rock with a sugary texture that we call "marble".

Most septaria have roughly oblate spheroidal shapes and overall argillitic limestone or dolostone compositions, except for their septa. The coarse-grained "septa" are usually quite evident in field exposures because they tend to weather either more or less deeply than the main parts of these concretions (see Figure A).

About Northeastern Cave Conservancy

The mineral in the limestone that gets dissolved is called calcite. Another mineral that can dissolve is called dolomite. It is found in a rock called dolostone. Limestone and dolostone are called sedimentary rocks, because they were laid down as sediments. Marble is made by putting limestone or dolostone under great heat and pressure.
