Greetings, Fellow CPers!
Here's the next batch of pics - these are goodies I found in my August rock hounding treks. Some of them I can identify, others, not so much - so any help from all you CP experts is appreciated!
First up, one of the more exciting finds of the summer - check out these lovely bivalve fossils! I've never found marine fossils before!

(Note for newbies and guests: collecting is not allowed in the Paint Mines Interpretive Park, so don't do it
- there's plenty of other, legal places to go!)

All the samples shown below are from the same roadbed in an area with many historic gold mines - I took several photos with varying light sources. The single sample is a no-brainer, with the telltale bronze color and cubic shape of chalcopyrite. But what about the other three? Distinctly different color, no crystalline shape to speak of, looks like gold sprinkles covering the face of each sample. Is it Au (or Au/Ag telluride)? How can I tell for sure?
Cheers!
