All of these samples were collected at Hogen Camp Mine, Harriman State Park, NY. The first image is a reflected light image of the ore vein. The ore vein formed as a result of dextral shear which ultimately created large fractures. Shortly after this, hydrothemal alteraltion occured of the metavolcanic gneiss in the region (image 2 and 3). The metavolcanic gneiss is rich in iron. Due to this, the highly acidic metamorphic fluids began to precipitate in the fractures. The process yeilded magnetite, clinopyroxene, and less common biotite within the fractures occuring at Hogen Camp Mine. The clinopyroxene and biotite are highly rich in iron.
Image 3 and 4 is the local pink pegmatites that occured in the region around 923 Ma. The pegmatitic dikes formed post-Ottawan orogeny. Composition includes: alkali feldspar with minor constituents of clinopyroxene and quartz.
This rock is a quartzofeldspathic gneiss from Surebridge Mine in Harriman State Park, NY. What’s so cool about this is you can see the hydrothermal process which alters biotite to chlorite. The large brown grain being biotite, and the purple/blue/green in the center being chlorite. (10x XPL)
“I was defiant,” she says. “Hell-bent on surviving. On making it. But it was hard and it was lonely, and I had to dare myself every day to keep going. Sometimes I would play the victim and cry in my shoe box of a bedroom with a window that faced a wall, watching the pigeons shit on my windowsill. And I wondered if it was all worth it, but then I would pull myself together and look at a postcard of Frida Kahlo taped to my wall, and the sight of her mustache consoled me. Because she was an artist who didn’t care what people thought. I admired her. She was daring. People gave her a hard time. Life gave her a hard time. If she could do it, then so could I.”
All hail the Queen.
