What is Limestone? (with pictures)
The Durdle Door sea arch formed as the ocean eroded limestone along the coast of southern England. The key mineral present in limestone is calcium carbonate, but the rock is often mixed with other mineral impurities. These impurities can dramatically alter the texture of the rock, along with its color.

Geology: What gemstones are found during limestone mining ...
Answer (1 of 4): Gemstones form inside limestone when water carrying dissolved minerals pools inside cracks or voids in the limestone, either seeping down from the surface or forced up from below by geothermal activity. The minerals in the water slowly crystallize out into gemstones. What kind of...

Limestone
Limestone is a very common sedimentary rock consisting of calcium carbonate (more than 50%). It is the most common nonsiliciclastic (sandstone and shale are common siliciclastic rocks) sedimentary are rocks that are composed of mostly calcium carbonate (minerals calcite or aragonite). Carbonate rocks where the dominant carbonate is dolomite (calcium magnesium .

Based on the mineral composition analysis of BIBSEM images, the Cobourg limestone can be characterized as a tight rock dominated by calcite grains of variable sizes (µm –cm) surrounded by idiomorphic or subhedral minerals (quartz, dolomite, and pyrite) and meshy clay minerals.
Mineral Precipitation
· This image shows a vein of calcite that precipitated in a fissure cutting through conglomerate. Calcite filled veins are fairly common in many geologic settings. This exposure is along the coast near Pigeon Point in San Mateo County. These travertine (freshwater limestone) deposits are in Mitchell Caverns in southern California.
Nummulitic limestone – El medi natural del Bages
Nummulitic limestone. The nummulitic limestones are made of cemented skeletons or shells of nummulites. Both, the nummulites and the cement are calcareous nature. Nummulitic limestones are characteristic from the Eocene epoch, in the Tertiary period. The nummulitic limestones deserve one close look. The lentil shaped fossils of nummulites are seen.
What Are the Characteristics of Limestone?
· What Are the Characteristics of Limestone? Limestone is a common type of sedimentary rock with a high calcium carbonate composition. Due to its calcium content, limestone is a soft rock that erodes easily. Like other sedimentary rocks, limestone forms from layers of other material that undergoes compression over time.
