| Na3(Fe,Mg)4(Fe,Al)Si8O22(OH)2 - Occurs as brilliant black prismatic crystals up to many centimeters in length in mariolitic cavities and and as acicular aggregates in pegmatitic portions of the alkali granite. Also occurs as inclusions within smoky quartz. | |
| (K,Na)3(fe,Mn)7Ti2Si8O24(O,OH)7 - Occurs as bronze micaceous bladed aggregates with metallic luster in some miarolitic cavities and as massive aggregates in pegmatitic portions of the alkali granite. Some smoky quartz crystals contain brilliant thin transparent red blades of astrophyllite. | |
| CeCO3(OH,F) - Occurs as mm-scale orange prismatic hexagonal crystals. | |
| KAlSi3O8 - Occurs as opaque white crystals to 1 cm lining miarolitic cavities. | |
| (Na,Ca)3(Y,Ce)12Si6B2O27F14 - Occurs as rare tan to peach colored crystals typically less than 1 mm. | |
| SiO2 - Occurs as milky to smoky crystals lining pockets up to a few decimeters in length. Some quartz is gemmy with a smoky-amethyst coloration. Inclusions of arfvedsonite, astrophyllite, or other species are common. | |
| Na2Fe+32Fe+23(Si8O22)(OH)2 - Occurs as acicular opaque dark blue-green crystals. Some riebeckite is absestiform. | |
| FeCO3 - Occurs as mm-scale rhombohedra in miarolitic cavities. | |
| NaLiZrSi6O15 - Occurs as white to gemmy pink crystals to 3.7 cm. Zektzerite fluoresces green under short-wave ultraviolet light. | |
| ZrSiO4 - Individual crystals to about 1 cm occur within some cavities. Specimens are brown, lusterous, and exhibit tetragonal prism faces. |
