Was a beautiful day out yesterday so I went out to the hayman burn area to do some poking around and test flight with my drone. I'm still learning my common minerals so thought I'd just take a stab at some. Is this Quartz in Porphyritic Rhyolite?

I have found it difficult to tell the difference between granite and rhyolite. Only thing I know is that rhyolite seems to be more porous due to surface cooling and granite is a little more dense?

I have been fairly idle in this endeavor, but hoping to find time again to dive in.
I have bought these Geologic Survey Bulletins from a guy in Lakewood, but found them online as well. I don't realize their full value yet, but they are interesting. Bulletin -------------------- -dbx-
