Crystalline Limestone. Crystalline Limestone is a rock that results from the crystallization of the calcite in sedimentary limestone. More or less of the calcite may have been replaced by carbonate of magnesia, forming dolomitic limestone; or, when the replacement has gone far enough, the rock becomes dolomite.
How Does Marble Form? | Reference.com
Marble is a soft metamorphic rock that forms at the edges of tectonic plates, where limestone is exposed to regional metamorphism. The heat and pressure of the metamorphic zone force calcite inside the limestone to recrystallize and merge into the classic marble consistency. Marble begins as limestone near the edges of tectonic plates.

Metamorphic Rocks Lesson #14 | Volcano World | Oregon ...
Metamorphism can be instantaneous as in the shearing of rocks at plate boundaries or can take millions of years as in the slow cooling of magma buried deep under the surface of the Earth. There are three ways that metamorphic rocks can form. The three types of metamorphism are Contact, Regional, and Dynamic metamorphism.

Metamorphic Rocks - darkwing.uoregon.edu
There are two primary types of metamorphism: Regional Metamorphism occurs on a large scale, typically involving hundreds of square kilometers of surface area. It is the most widespread of the metamorphic types and is typical of the major fold-mountain belts such as the Appalachians, Himalayas, Alps or Rocky Mountains.
Contact Metamorphism - an overview | ScienceDirect Topics
The rocks of contact metamorphism are hornfels created from clay and pelite sediments and/or tuffs. The skarn rocks are created from marl and clay limestone and dolomite (Table 6.1). The contact metamorphic marbles occur at the contact of the magma or lava with limestones and dolomites.

6 Metamorphic Rocks – An Introduction to Geology
6.4 Metamorphic Environments. As with igneous processes, metamorphic rocks form at different zones of pressure (depth) and temperature as shown on the pressure-temperature (P-T) diagram. The term facies is an objective description of a rock. In metamorphic rocks facies are groups of minerals called mineral assemblages. The names of metamorphic facies on the pressure-temperature diagram reflect ...
ALEX STREKEISEN-Calc-Silicate Marble-

The metamorphism of siliceous dolomitic limestone is considered with the aid of a composition tetrahedron which suggests that the changes may be referred to thirteen steps or grades of increasing decarbonation, taking place at successively higher temperatures at any given pressure.

Marble is a metamorphosed carbonate rock derived from limestone's and dolomites. It is produced by contact as well as dynamic metamorphism. Marbles range in texture from fine to relatively coarse varieties in which the grains are clearly visible to the unaided eye.
Can metamorphism change the mineral composition of rock ...
Compositionally simple sedimentary rocks, such as quartz sandstone and limestone (calcite) do not change composition with metamorphism - their chemistry is too simple. We can see this in the chart below where sedimentary shale turns into slate, then phyllite, then schist, then gneiss.
Kinds of Metamorphism - csmgeo.csm.jmu.edu
Sometimes this is referred to as " regional metamorphism" but since it is not the only metamorphism to take place on a regional scale Barrovian is a more precise name. Barrovian metamorphism produces some of the most common metamorphic rocks, many of which are spectacularly beautiful and thus used as building stones.

A skarn is formed by a variety of metasomatic processes during metamorphism between two adjacent lithologic units. Skarn can form in almost any lithology type such as shale, granite and basalt but the majority of skarns are found in lithology containing a limestone or a dolomite.
