breccia mechanical properties

Breccia Classification, Composition, Formation, Properties

The identifying feature of breccia is that it consists of visible angular clasts cemented together with another mineral. The clasts should be easily visible to the naked eye. Otherwise, the properties of the rock are highly variable. It can occur in any color, and may be either hard or soft.

Breccia an overview ScienceDirect Topics

Breccia generated by folding, faulting, magmatic intrusions and similar forces are called “tectonic breccia”. Tectonic breccia zones are represented by crush, rubble, crackle and shatter rock mass. Breccia and conglomerate are similar rocks with difference in shape of the larger particles due to transportation mechanism.

Breccia Wikipedia

Breccia (/ ˈbrɛtʃiə / or / ˈbrɛʃiə /) is a rock composed of broken fragments of minerals or rock cemented together by a fine-grained matrix that can be similar to or different from the composition of the fragments. The word has its origins in the Italian language, in which it means "rubble".

Anorthosite Wikipedia

Anorthosite / æ n ˈ ɔːr θ ə s aɪ t / is a phaneritic, intrusive igneous rock characterized by its composition: mostly plagioclase feldspar (90–100%), with a minimal mafic component (0–10%). Pyroxene, ilmenite, magnetite, and olivine are the mafic minerals most commonly present.. Anorthosites are of enormous geologic interest, because it is still not fully understood how they form.

Breccia Rock Assignment Point

Definition Breccia (/ˈbrɛtʃiə/ or /ˈbrɛʃiə/) lithified sedimentary rock consisting of angular or subangular fragments larger than 2 millimeters (0.08 inch). It differs from a conglomerate, which consists of rounded clasts. The spaces between the large angular fragments are filled with a matrix of smaller particles and a mineral cement that binds the rock together.
