I was rather shocked at the colors when washing off this scraper. I have outcrops of granite, basalt, sandstone, quartzite, and quartz, so A LOT of gray, brown, and white. Any ideas on the material? I included another chunk of it-wet and dry to help ID it.
And any suggestions for a good geology/lithic material reference book? Cecilia? Looking for a book with many pictures. Gaining lithic knowledge on the internet is so tedious. I’ve been compiling some of my own reference materials with weathering, patina, and freshly broken, but a book would be so much easier.
