Fig. 1 Pochuck pyroxenite forming part of the footwall of a small open 
cut at the Clove mine, Orange county. Taken in polarized light, nicols 
crossed magnification 35 diameters. The rock is made up of a colorless 
monoclinic pyroxene, essentially diopside, a monoclinic hypersthene (“ clino- 
hypersthene”), a little hornblende, and magnetite distributed both inter- 
stitially and cutting the silicates as well, showing its magmatic end-stage 
relationship. The black areas are magnetite. 
Fig. 2 Pochuck pyroxenite extensively modified. From an old dump, 
Clove mine. All of the ferromagnesians have been wholly changed by 
magmatic end-stage processes to fine flaky talc, spherulitic chlorite, serpentine, 
phlogopitic mica, and dendritic magnetite (the black, branching material). 
Solid black is earlier end-stage magnetite. Light polarized, nicols crossed, 
X 35.
