Idaho Geology Final

What type of fault

Tension Stress is

Craters of the Moon is located here

The largest form of pluton

Shear Stress is

The Bonneville flood broke through this location

Large region of mountains caused by tension which created normal faults

Deposits from rivers or streams

Scars of many supervolcano eruptions are found here

The remains of a volcanic vent or main chamber

Any body of igneous rock that has been crystallized deep below the earth's surface

When sediments are laid down in layers

The 3 types of sedimentary rocks

This formed Shoshone Falls

A Vertical Tabular Pluton

This geologic feature is additional proof that Idaho was once the west coast of America

Sits in a normal fault bounded graben

Caused by an overflow of an ancient glacial lake

Much of the geology in the Stanley area is from this geologic province

What type of fault

Bogus Basin Ski Area is located here

Deposits from mountain streams or flood events

Compression Stress is

Any pluton that has been injected between layers

Deposits from a dune area

In the picture shown the block on the left is called the

Large region of mountains caused by tension which created normal faults

A horizontal tabular pluton that has not bulged the layers above it

Regression Suite of Rocks

The Bonneville floods discharge rates were this many times that of the normal Snake River flow

Mushroom Shaped pluton

Stretching of the crust made Rhyolite domes/flows that covered much of Idaho's earlier geology.

This forms the center of the state and is mainly granitic rocks

Forms as the North American plate moves west over the Yellowstone Hotspot

Deposits from a lake

Wallowa and Blue Mountain ranges are here

Formed when Islands on the Pacific Plate were smashed into the North American Plate

In the picture shown the block on the right is called the

What type of fault

Igneous Rock with fine crystals

Craters of the moon is located here
