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.

(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.

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.

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.

A name given to the resource
Mudlick Latite
Description
An account of the resource
Hand Sample: Porphyritic latite with medium-to-coarse-grained subhedral plagioclase phenocrysts in a brown-black groundmass. Thin black veins present with green margin of contact on either side.
Thin Section, XPL: Medium-grained subhedral phenocrysts of plagioclase feldspar, quartz, and microcline feldspar in a matrix that appears to be made from the same minerals. Very fine vein of greenish minerals runs through sample.

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.
