Hornblende Diorite
Some alteration has produced epidote, most of the hornblende is prismatic and occurs in two colors
Hornblende Syenite
Contains sutured grain boundaries, conversion of hornblende to magnetite, and some fine-grained alteration products
Kershaw Pink Granite
Quartz and feldspar exhibit fracturing
Norite
Contains biotite, orthoclase, hornblende, quartz, and titaniferous magnetite
Olivine Diabase
Ophitic texture in thin section, some opaques
Olivine Gabbro
Gabbro associated with syenite ring dike near Concord, North Carolina
Panola Granite
Quatz appears strained, microcline is altered to muscovite and sericite, biotite is altered to chlorite
Petersburg Granite
Extensively used in highway construction
Pinckneyville Granite
Biotite forms lineation in some hand specimens, much of the quartz and feldspar is fractured
Porphyritic Biotite Granite
Fedlspar and quartz exhibit fracturing
Porphyritic Biotite Granite
Biotite and feldspar are aligned, giving the rock a texture like porphyroblastic gneiss, some feldpsar has been altered to sericite, and some larger feldspar crystals are fractured
Porphyritic Rhyolite
Contains orthoclase, ligoclase, and quartz phenocrysts and has alterations of kaolinite, sericite, and epidote
Porphyritic Rhyolite
Quartz and feldspar phenocrysts, rounded diabase inclusions
Quartz Gabbro
Plagioclase altered to epidote and flaky sericite, rock has undergone slight metamorphism
Quartz Monzonite
Some feldspar shows slight alteration
Rhyolite
Phenocrysts of lath shaped feldspars and beta quartz
Salisbury Pink Granite
Quartz and feldpsar grains are closely interlocked and grains appear to be shattered
SE Suite PDF
Stone Mountain Granite (Adamellite)
Mostly quartz, oligoclase, and microcline
Syenite
Similiar in composition, texture, and shape to the Concord, North Carolina complex
