Summary[edit]

Description

Igneous dike in the Eocene of Wyoming, USA.

Igneous dikes are planar to irregularly-planar igneous intrusions that cut across country rocks. They can be thin or extremely thick & they can be vertical or obliquely-oriented.

The wide, medium-gray colored body is an andesite dike that is intruding Eocene-aged volcanic debris flow conglomerates.
