Is Granite Porous Geology

As previously mentioned granite is of an igneous nature which makes it less porous than sedimentary rocks such as limestone and travertine.

Is granite porous geology.

I type igneous granites appear to arise from the melting of preexisting igneous rocks s type sedimentary granites from melted sedimentary rocks or their metamorphic equivalents in both cases. But in the parlance of the natural stone industry the definition of granite is expanded to include all igneous rocks as well as many metamorphic rocks like gneiss and schist. Alas its porous surface is granite s kryptonite. This means that if it is not properly sealed liquid is able to penetrate its surface.

The following is a list of rock types recognized by geologists there is no agreed number of specific types of rocks. In geology granite is one specific thing. Granite is a porous natural stone. Strictly speaking granite is an.

Also granite is immune from the damages of most common household acids. Felsic rocks are less dense than mafic and ultramafic rocks and thus they tend to escape subduction whereas basaltic or gabbroic rocks tend to sink into the mantle beneath the granitic rocks of the continental cratons. Granite has a felsic composition and is more common in recent geologic time in contrast to earth s ultramafic ancient igneous history. Granite is a rock with interlocking grains.

A more precise definition is used by petrologists geologists who specialize in the study of rocks. Sandstone is a rock with rounded grains. An igneous rock that is coarse grained and overall light colored. What granite means.

Students of granites classify them in three or four categories. Any unique combination of chemical composition mineralogy grain size texture or other distinguishing characteristics can describe a rock type. In the case of marble which is metamorphic as well as sedimentary porosity can be considerably higher when compared to granite up to 2 percent. Like all natural stone granite is susceptible to liquid sinking into its surface.

And the definition of granite expands wildly when used by people who sell dimension stone such as countertops tile and building veneer. If liquid or stains get down into the stone it can result in damages and weakening of your granite. Granite ˈ ɡ r æ n ɪ t is a common type of felsic intrusive igneous rock that is granular and phaneritic in texture. Other types of rock have rounded grains.

A simple definition is used in introductory courses. The word granite is used in a variety of ways by different people. M type mantle granites are rarer and are thought to have evolved directly from deeper melts in the mantle. So porous rocks tend to be softer than non porous rocks.
