Non foliated rocks, such as marble, form from limestone, a common type of sedimentary rock. Foliated rocks form from metamorphic or igneous rocks. Non Foliated rocks are more brittle than foliated rocks making them more susceptible to breakage.
Probably the foliated slate, because there is a line in which to break it. Plus, slate is like the easiest material to break.
Foliated rock, like slate, is easy to break.
foliated: contain aligned grains of flat minerals
non foliated: aren't aligned minerals, contain few minerals which make it harder to break and yomama by raymond
Sedimentary rock can appear foliated, but the nomenclature of foliation is usually reserved for the context of metamorphic rock texture description.
Chert is non-foliated. Foliation is a term that is used mainly to describe the appearance or texture of metamorphic rock. Chert is a sedimentary rock, composed mostly of microcrystalline quartz.
A banded texture
Non-foliated metamorphic rock, like quartzite and marble.
Foaliated rock can form in one or two ways. Extreme pressure may cause the mineral crystals in the rock to realign or regrow to form parallel bands. Foaliation also occurs as minerals that have different compositions separate to produce a series of alternation dark and light bands. Most nonfoliated metamorphic rocks share at least one or two main characteristics. First, the original rock that is metamorphosed may contain grains of only one mineral or contains very small amounts of other minerals.
It is nonfoliated.
Nonfoliated
Slate is a foliated metamorphic rock.
Rock salt is not foliated.
Foliation is an attribute of certain metamorphic rocks. Sandstone is a sedimentary rock that is not described as foliated or non-foliated.
cleavage, metallic, foliated, nonfoliated, and gravity.
Sedimentary rock can appear foliated, but the nomenclature of foliation is usually reserved for the context of metamorphic rock texture description.
You can determine because there is texture differences. Also, foliated rocks have visible layers or elongated grains of minerals. Nonfoliated does not have distinct layers or bands.
Breccia is a rock composed of broken fragments of minerals or rock. It is mostly quartz, feldspar, and clay minerals and is not foliated.
The Process. Both foliated and nonfoliated rocks begin their lives as either sedimentary, igneous or another metamorphic rock. Type of Pressure. If the pressure applied to the recrystallizing rock is unequal, then a foliated rock will form.
Halite is a rock-forming mineral that precipitates from an aqueous solution (e.g. sea water) and therefore, is not foliated.
