Breccia Mechanical Properties

Breccia Classification, Composition, Formation, Properties ...

Breccia is a clastic sedimentary rock that shaped from angular and boulder size clasts cemented or in a matrix. The angular shaped of clast show that they have not been transported from their source. There are numerous modes of formation for breccia. Some constitute consolidated material accumulated on steep hill slopes or on the foot of cliffs.

This breccia is not related to acid spill, and so it can be inferred that the arrangement is a result of ...

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.
