What type of rocks are in the grand canyon rock layers?

Answer 1

its is made up of Kaibab limestone, Toroweap formation, Coconino sandstone, Hermit shale, Supai group, redwell limestone, Mauv limestone, bright angel shale, Tapeats sandstone, and Vishnu schist.

Answer 2

Igneous rocks

are formed

when rock is super-heated and

becomes molten (liquid). There are two kinds of

molten rock: magma (found beneath the Earth's surface) and lava (found on the Earth's surface). The molten rock cools and hardens on or beneath the Earth's surface forming a variety of igneous rock. Two examples are granite and basalt.

Sedimentary rocks are made of smaller pieces (like sand or mud), called sediments, that pile into layers. As pressure on the sediment increases over time, minerals act like glue, cementing them into solid rock. The three main types of sedimentary rocks at

Grand Canyon are sandstone, shale (or mudstone), and limestone.

Metamorphic rocks are rocks that

have been

changed

under

great heat

and pressure. The original rock can be sedimentary, igneous, or even metamorphic. The original rock is changed into something new, just as a caterpillar "metamorphoses" into a butterfly.

Precambrian Basement Rocks

The basement rock formed 1.8 billion years

ago when the North American continent

collided with an ancient chain of volcanic

islands, much like today's Hawaiian Islands.

Intense heat and pressure from the collision

formed the metamorphic rock called Vishnu

Schist. From deep under the earth's surface,

molten rock flowed up as magma between the

cracks of the Vishnu Schist. As the flowing

magma cooled and hardened, it formed

igneous rock called Zoroaster Granite.

Because of the extreme heat and pressure that folded and changed the metamorphic rock, it is hard to find any fossils in the basement rocks.

Bright Angel Shale

If you came to Grand Canyon area 515 million years ago when the Bright Angel Shale was forming, everything was covered by a very muddy, warm, shallow sea. Trilobites, brachiopods, crinoids and worm-like creatures that burrowed in the sea-floor thrived in the nutrient-rich water. This greenish-colored shale forms the broad, flat area known as the Tonto Platform in Grand Canyon.

Redwall Limestone

About 340 million years ago, North America lay close to the equator when the Redwall Limestone formed. Grand Canyon was covered by a shallow, warm, clear and well-lit sea where many crinoids lived. Fossils in the rock tell us that corals, cephalopods, bryozoans, and brachiopods lived here. While the limestone itself is gray in color, the surfaces of the exposed cliffs are stained red by iron in rock eroding from the layers above with rain and snow melt.

Supai Group

How do you feel about a trip to the beach? About 300 million years ago, the Grand Canyon area was covered by rapidly changing Coastlines as sea levels rose and fell. The Supai group has limestone, sandstone, and shale in it, sharing the story of beaches, dunes, and sometimes oceans that were found here. The ocean environments left behind fossils of brachiopods, while the land environments left various plant fossils for geologists to find. Both environments contained multiple types of burrowing creatures.

These are just a few! they have many more!
