Igneous Rock Bodies (Intrusive)
Dike, Volcanic Neck
This picture from Shiprock, New Mexico, shows the remains of a volcano at the right, and a weathered out igneous dike (vertical) at the left.
A very small dike visible in a pebble.
A view of the Sierra Nevada batholith, Yosemite National Park. This is actually not a single intrusive body, but rather a composite that consists of over 100 successively intruded bodies.
The dark layer in the upper half of the picture is an igneous sill (basaltic in composition) that was injected between layers of sediment.
