Summary

Index No: MRTN100450; Collected By: Thomas B. Nolan; Sample Type: hand sample; Notes: Location taken from Tonopah Extension Mine shaft; Groundmass is green. The only phenocrysts are yellowish-white feldspars. These are rather sparse, and most are very small. Some are larger, up to 2 mm. There has probably been some recrystallization in these. The rock as a whole has a faint suggestion of vesicular character, tho this may be due to alteration. Considerable pyritization.
