How do you recognize limestone and marble – USGS

The main difference between limestone and marble is that limestone is a sedimentary rock, typically composed of calcium carbonate fossils, and marble is a metamorphic rock. If you look closely at a limestone, you can usually see fossil fragments (for example, bits of shell) held together by a calcite matrix.

LIMESTONE The boundary between the two is well studied and usually not difficult to distinguish as significant changes occur to the calcite crystals during metamorphism. It is composed mostly of the mineral calcite.

Calcium carbonate is the main component that forms shells, and when marine life dies those shells settle on the bottom of the ocean where they collect.

Limestone – Rock Uses, Formation, Composition, Pictures

In the late 1700's a printing process (lithography) was developed to reproduce images by drawing them on the stone with an oil-based ink and then using that stone to press multiple copies of the image. Limestone is a sedimentary rock composed primarily of calcium carbonate (CaCO3) in the form of the mineral calcite.

Phys.org – limestone

Limestone is a sedimentary rock composed largely of the minerals calcite and aragonite, which are different crystal forms of calcium carbonate (CaCO3). The ability to tell the difference between crystals that formed naturally and those formed by human activity can be important to archaeologists in the field.

Member 2 of the Edwards Limestone is about 12 meters (40 feet) of thin bedded, fine-grained, dolomitic limestone, and fine-grained flaggy limestone.

Rock Lore & Tidbits: The word calcite comes from the latin word calx, and the Greek word chalix, meaning "lime". Calcite is common in limestone and marble. This makes it an excellent stone for distance healing, as well as other types of healing.

Geological Survey Limestone – DNR

The amounts of calcite and dolomite in theoretically pure limestone range continuously from all calcite and no dolomite to all dolomite and no calcite as shown in the accompanying table. Limestone may be divided into four different kinds based on weight percents of calcite and dolomite in the total carbonate portion.
