Feel free to correct me on any of these minerals. I am not an expert, they are just what I have found them to be after researching on my own. I would like to know what something is if I have been mis-identifying it
Nice selection of finds Auger!
I am not an expert either but I have a few possible corrections for you:
Banded Agate= If this was found in the volcanic area then it could be opal.
Copper on Quartz= It is unlikely to be copper on there but it looks similar to the mica inclusions/coatings that I find on some of the pockets I have found.
Limestone= If the rock is limestone then it should bubble in vinegar and make SIO bubble more than usual. Not sure what the vein is but the star shape is cool.
Volcanic Ash= Ash is usually light grey. That looks like volcanic Basalt with Zeolites. Looks like you have several of the zeolite minerals on there. Calcite can form in the zeolites as well.
Hematite= Hematite pseudomorph after Siderite. Siderite likely formed first making the tilted block shape of the crystals, then Hematite came into the system and replaced it. This is somewhat common for the iron bearing minerals to replace each other. (goethite, hematite, siderite...)
Iron Pyrite= I don't see any pyrite in the pic but the black block looks like it could be a Columbite-Tantalite crystal. Which shows up in the pegmatite areas.
Petrified Brie Cheese= Chalcedony.
