Breccia is an inorganic land-derived sedimentary rock. It is clastic (fragmental), but not foliated. Breccia is composed of mostly quartz, feldspar, and clay minerals; it may contain fragments of other rocks and minerals.

Is breccia foliated or nonfoliated?

Breccia is typically a nonfoliated rock, meaning that it lacks the aligned mineral grains or bands characteristic of foliated rocks. Breccia forms from the cementation of broken rock fragments, giving it a distinct angular appearance.


Is talc foliated or non foliated?

Talc is a foliated mineral. Foliated minerals have a layered or banded structure due to the alignment of mineral grains, giving them a distinct sheet-like appearance.


What determines whether a metamorphic is foliated or non- foliated?

The presence of aligned minerals in the rock determines if it is foliated or non-foliated. Foliated metamorphic rocks have minerals that are arranged in layers or bands, while non-foliated rocks do not show any preferred orientation of minerals. The amount of pressure and temperature the rock experiences during metamorphism also influences whether it will develop a foliated or non-foliated texture.


What classification of metamorphic rocks would include whether they are?

Foliated or non-foliated. Foliated metamorphic rocks have a layered or banded appearance due to the alignment of minerals, while non-foliated rocks do not exhibit this feature.


What is the specific gravity of breccia?

The specific gravity of breccia can vary depending on its composition. On average, the specific gravity of breccia is around 2.5 to 2.8. Breccia is a type of rock made up of various fragments cemented together, such as broken pieces of other rocks, which influences its specific gravity.
