Title
A name given to the resource
(SFM) Igneous Suite -- St. Francois Mountains, Southeastern Missouri
Description
An account of the resource
This collection is composed of igneous volcanic and intrusive rocks from the St. Francois Mountains of Missouri. The variation within the collection can be used to explain the geologic history of the area. The St. Francois Mountains batholith was formed by granitic intrusions into Precambrian rhyolites, tuffs, and breccias. Then basalt, diabase, and porphyritic intrusions cut the granitoids.

(SFM) Igneous Suite -- St. Francois Mountains, Southeastern Missouri
Description
An account of the resource
This collection is composed of igneous volcanic and intrusive rocks from the St. Francois Mountains of Missouri. The variation within the collection can be used to explain the geologic history of the area. The St. Francois Mountains batholith was formed by granitic intrusions into Precambrian rhyolites, tuffs, and breccias. Then basalt, diabase, and porphyritic intrusions cut the granitoids.

Description
An account of the resource
This collection is composed of igneous volcanic and intrusive rocks from the St. Francois Mountains of Missouri. The variation within the collection can be used to explain the geologic history of the area. The St. Francois Mountains batholith was formed by granitic intrusions into Precambrian rhyolites, tuffs, and breccias. Then basalt, diabase, and porphyritic intrusions cut the granitoids.

This collection is composed of igneous volcanic and intrusive rocks from the St. Francois Mountains of Missouri. The variation within the collection can be used to explain the geologic history of the area. The St. Francois Mountains batholith was formed by granitic intrusions into Precambrian rhyolites, tuffs, and breccias. Then basalt, diabase, and porphyritic intrusions cut the granitoids.
