Miarolitic cavities with amazonite, albite, smokey quartz and polylithionite.
Quartz pegmatitic cores with microcline and siderophyllite in the Pike's Peak batholith.

The Lake George Ring complex contains numerous ring dikes of quartz syenite to fayalite granite that are distributed around a central stock of quartz syenite to syeno-monzonite.

The complex is located in the south-western portion of the Pikes Peak batholith.

Very approximate coordinates for the centre of the complex.
