Is Sandstone More Permeable Than Granite

To a geologist the word sand in sandstone refers to the particle size of the grains in the rock rather than the material of which it is composed sand size particles range in size from 1 16 millimeter to 2 millimeters in diameter.

Is sandstone more permeable than granite.

Granite and sandstone both are used in interior and exterior home designing projects. Granite dependsmarble on chosen rocks crystals large heavy igneous sandstone grains depends on chosen rock depends on chosen rock lighter than granite sedimentary crystals large heavy metamophic slate crystals small light metamorphic chalk grains small light sedimentary basalt crystals small depends on amount of. Sandstone is defined as a rock which is composed of sand sized grains of various minerals mostly of uniform size and often are smooth and. The types of sandstone are grey sandstones crystallized sandstones hard sandstones carbonate cemented sandstones and ganister whereas types of shale are red shale black shale green shale grey shale and yellow shale.

Granite is available in white black grey orange pink colors. The hardness of granite and sandstone is varying between 6 7. Granite is relatively non porous compared to other common countertop materials though it still has some porosity. The least permeable rocks are unfractured intrusive igneous and metamorphic rocks followed by unfractured mudstone sandstone and limestone.

The hardness of sandstone is 6 7 and that of shale is 3. The rock which contain more than 95 of calcium carbonate is known as high calcium limestone recrystallised limestone takes good polish and is usually used as decorative and building stone. They both have different physical properties depending upon its nature. On the other end of the spectrum is sandstone with its large individual sand grains.

Sandstone is easy to work and install. Limestone and sandstone are highly porous and readily absorb liquids and are particularly prone to etching and wearing away when they come into contact with acids. Granite is a very hard granular crystalline igneous rock which consists mainly of quartz mica and feldspar and is often used as building stone. You can also know more about granite and sandstone reserves.

Unconsolidated materials are generally more permeable than the corresponding rocks compare sand with sandstone for example and the coarser materials are much more permeable than the finer ones. In crystalline rocks like granite which have tight interlocking mineral grains porosity is normally quite low less than 1 percent. This is measured either as a decimal between 0 and 1 or as a percentage. A part of calcium molecules if being replaced by magnesium it is known as magnesium lime stone or dolomite limestone.
