metamorphic
This type of sedimentary rock is called a "nonconformity." It occurs when younger sedimentary layers are deposited on top of older, often deformed or eroded, igneous or metamorphic rocks. Nonconformities indicate a significant gap in the geological record due to erosion or tectonic activity.
Igneous rock forms from molten rock that cools and solidifies, either above or below the Earth's surface. This process can result in the formation of rocks such as basalt, granite, and obsidian.
an ingenous rock is type of rock formed when lava or magma cools and hardensIt's igneous rock, not ingenious rock. Igneous rock is lava that has hardened into stone. Two examples are obsidian and pumice.
An igneous rock is a type of rock that forms from the cooling and solidification of magma or lava. It can be either intrusive (formed below the Earth's surface) or extrusive (formed on the Earth's surface). Examples include granite, basalt, and obsidian.
The type of rock that likely formed first to initiate the rock cycle is igneous rock.
No. But a Sedimentary rock, Organic.
Nonfoliated rock
Yes, a metamorphic rock with no banding is classified as a nonfoliated rock. Nonfoliated rocks do not exhibit the layering or banding commonly seen in foliated rocks due to the recrystallization process they undergo during metamorphism.
Quartzite is a nonfoliated metamorphic rock that is granular and composed mainly of quartz. It forms from the metamorphism of quartz-rich sandstone.
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.

Metamorphic rocks can be identified if the rock is foliated or nonfoliated, foliating type, type of metamorphism (contact/regional), and by probable original rock. :)
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.
sedimentary rock.
* Foliated (banded) - minerals oriented along visible planes * Example: Schist (fine grain) (from slate) * Example: Gneiss (coarse grain) (from a variety of rock, one of which is granite) * Non-foliated (no banding) usually rock of one mineral) * Example: Quartzite (from sandstone - quartz) * Example: Marble (from limestone - calcium carbonate
The most powerful rock type move is either rock wrecker and head smash
Marble is a metamorphic rock that is massive and lacks banding. It forms from the recrystallization of limestone and is composed mostly of the mineral calcite. Marbles are often used in architecture and sculpture due to their aesthetic qualities.
