1 Definition
1.1 Definition
Breccia is a rock consisting of angular fragments of stones which are cemented by finer calcareous material
Gneiss is a common and widely distributed type of rock formed by high-grade regional metamorphic processes from pre-existing formations that were originally either igneous or sedimentary rocks

5.1 Formation
Breccia is a clastic sedimentary rock which is composed of broken fragments of minerals or rock which are cemented together by a fine-grained matrix and it forms where broken, angular fragments of rock or mineral debris accumulate.
Gneiss is a high grade metamorphic rock i.e. it has been subjected to higher temperatures and pressures than schist. It is formed by the metamorphosis of Gneiss forms from volcanic rock, shale or granitie.

Breccia vs Gneiss Information

Earth’s outer layer is covered by rocks and these rocks have different physical and chemical properties. As two rocks are not same, it’s fun to compare them. You can also know more about Breccia and Gneiss Reserves. Breccia is a rock consisting of angular fragments of stones which are cemented by finer calcareous material. Gneiss is a common and widely distributed type of rock formed by high-grade regional metamorphic processes from pre-existing formations that were originally either igneous or sedimentary rocks. These rocks are composed of many distinct minerals. The process of formation of rocks is different for various rocks. Rocks are quarried from many years for various purposes. You can check out Breccia vs Gneiss information and Breccia vs Gneiss characteristics in the upcoming sections.

Breccia vs Gneiss Characteristics

Though some rocks look identical, they have certain characteristics which distinguish them from others. Characteristics of rocks include texture, appearance, color, fracture, streak, hardness etc. Breccia vs Gneiss characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Breccia and Properties of Gneiss. Learn more about Breccia vs Gneiss in the next section. The interior uses of Breccia include Countertops, Decorative aggregates, Entryways, Floor tiles, Flooring, Homes, Hotels and Interior decoration whereas the interior uses of Gneiss include Countertops, Decorative aggregates, Flooring and Interior decoration. Due to some exceptional properties of Breccia and Gneiss, they have various applications in construction industry. The uses of Breccia in construction industry include As dimension stone, Construction aggregate, Landscaping, Roadstone and that of Gneiss include As dimension stone.
