Marble is a metamorphic rock composed of recrystallized carbonate minerals, most commonly calcite or dolomite. Marble is typically not foliated, although there are exceptions. In geology, the term "marble" refers to metamorphosed limestone, but its use in stonemasonry more broadly encompasses unmetamorphosed limestone.
Limestone is an unusual rock in that it fizzes when dilute acid is placed on its surface. It is the presence of calcium carbonate that is responsible for this. The calcium carbonate content of limestone rocks has been used from the earliest civilisations, dating back to 14,000 BCE, to its extensive use in modern times.

Limestone and (to a lesser extent) marble are reactive to acid solutions, making acid rain a significant problem to the preservation of artifacts made from this stone. Many limestone statues and building surfaces have suffered severe damage due to acid rain.
ROCKS- Introduction Rocks are made up of minerals. Minerals each have their own color, shape, hardness, way of splitting, and luster. Some rocks are made of only one mineral, such as marble, which is made of calcite. Other rocks are made up of many minerals. Granite is usually composed of quartz, feldspar, and mica.

The purpose of this experiment is to discover the reaction rate in which acid rain weathers marble statues, or in our case, marble chips. Introduction. Marble is especially sensitive to the degrading by acidic chemicals, also to weathering. Acid rain is one of the top degradation agents for marble artefacts around the world.

Buxiel Limestone is in gray base color, which is a kind of limited stock. As many marble stone, it has low abrasion resistance. It rates as a 1-3 on the Mohs scale. Light scratching will occur with exposure to sand and other abrasives. The finish will patina or dull over time as a result of this scratching.
Indiana Limestone was a favorite building material during the Art Deco period as new milling machines made possible the distinctive designs of the day. After the Great Chicago Fire, it was discovered that structures built with Indiana Limestone survived remarkably well. While durable, Indiana limestone can be damaged by age, neglect or heavy use.

Field Investigations of Acidic Deposition Effects on Limestone and Marble. Erosion Due to Dissolution. During the past several years, research in the effects of acidic deposition on carbonate stone has been conducted under the National Acid Precipitation Assessment Program (NAPAP) (2) to define the incremental effect of acidic deposition under
There are many different types of limestone formed through a variety of processes. Limestone can be precipitated from water ( non-clastic, chemical or inorganic limestone), secreted by marine organisms such as algae and coral (biochemical limestone), or can form from the shells of dead sea creatures (bioclastic limestone).
What is Marble? Marble is a metamorphic rock that forms when limestone is subjected to the heat and pressure of metamorphism. It is composed primarily of the mineral calcite (CaCO 3) and usually contains other minerals, such as clay minerals, micas, quartz, pyrite, iron oxides, and graphite.
