Granite is an igneous rock with grains large enough to be seen with the naked eye. It is light-colored and forms from the slow crystallization of mama below the Earth's surface. It is made up mainly of quartz and feldspar. There are also minor amounts of mica, amphiboles, and other minerals.

Igneous rocks are those that form via the process of melting and cooling. If they erupt from volcanoes onto the surface as lava, they are called extrusive rocks.By contrast, Intrusive rocks are formed from magma that cools underground. If the intrusive rock cooled underground but near the surface, it is called subvolcanic or hypabyssal, and often has visible, but tiny mineral grains.

Granite is an igneous rock and it forms from the slow crystallization of magma. It has a medium to coarse-grained texture and is composed mainly of quartz, feldspar, mica and other minerals. Due its mineral composition it is tougher and more resistant to stains, acids and abrasion than marble or limestone.

In the stone trade, marble also includes dense limestone and rocks that contain serpentine minerals. Due to it being much softer than granite it has been widely used throughout history in buildings, sculptures and monuments and continues to be used as flooring, cladding and a variety of domestic uses.
Test the composition of your rock by putting a few drops of ordinary white vinegar on it. If the vinegar foams, the rock is calcareous and this will affect the hardness and pH of the water. Limestone is probably the most frequently encountered calcareous rock, followed closely by marble.
Aug 16, 2013· Fieldstone is just that, stone found in a nearby field or woods that is used to mark a grave. These were some of our earliest grave markers.

Marble is a metamorphic rock resulting from the heating of limestone or dolostone.The heating may be regional due to the subduction of a limestone or may be the result of contact metamorphism where a magma intrudes into a limestone, resulting in partial melting.
Limestone may be crystalline, clastic, granular, or dense, depending on the method of formation. Crystals of calcite, quartz, dolomite or barite may line small cavities in the rock. Chert or Flint nodules are common in limestone layers. Bands of limestone emerge from the Earth’s surface in often spectacular rocky outcrops and islands.

Igneous rocks from left to right: gabbro, andesite, pegmatite, basalt, pumice, porphyry, obsidian, granite, and tuff. Molten rock material below the surface is called magma. Magma that has reached the surface is lava. Igneous rocks that solidified within the crust are plutonic (or intrusive) rocks.
Since sandstone looks and feels very different from granite and marble, it has become fashionable to use these in boutique stores. Steve Jobs famously saw a bluish-grey sandstone on a trip to Florence, and many years later insisted that that very stone be used in all apple stores because of its 'integrity'.
