Is Limestone a clastic sedimentary rock?
Limestone is a sedimentary rock consisting of more than 50% calcium carbonate ( calcite – CaCO 3).
Some limestones form from the cementation of sand and / or mud by calcite ( clastic limestone), and these often have the appearance of sandstone or mudstone..
What major rock type is a limestone?
Limestone is a common sedimentary rock that is composed mostly of the mineral calcite (CaCO3). It is produced by crystallization from water, or by accumulation of shells and shell fragments. Limestone, a sedimentary rock, is made up mainly of calcite, which is made up mainly of the skeletons of microsopic organisms.
What is a limestone classification?
Limestone is a type of carbonate sedimentary rock. It is composed mostly of the minerals calcite and aragonite, which are different crystal forms of calcium carbonate (CaCO3). A closely related rock is dolomite, which contains a high percentage of the mineral dolomite, CaMg(CO3)2.
Why is limestone classified as a sedimentary rock?
Limestone is usually a biological sedimentary rock, forming from the accumulation of shell, coral, algal, fecal, and other organic debris. It can also form by chemical sedimentary processes, such as the precipitation of calcium carbonate from lake or ocean water.
Is Limestone a clay?
Limestone clays are used in the ceramic segment in the manufacture of bricks, ceramic tiles, and in the production of cement, among others. Limestone can be present in soils in pure form or as a contaminant, but always from marine environments.

What are characteristics of limestone?
Some varieties of limestone have an extremely fine grain. Limestone is usually gray, but it may also be white, yellow or brown. It is a soft rock and is easily scratched. It will effervesce readily in any common acid.
What color is a limestone?
Natural limestone originally deposits in shallow sea beds and the color ranges from white, yellow, and gray to blue, beige, and cream. While the limestone color matters in the overall appearance of the stone, so does the finish placed on the stone.
Is limestone hard or soft?
As a natural product, limestone requires knowledge and understanding. The most common misconception about limestone is that it’s a soft stone. In reality, limestone can range from very hard to soft.
