1st - I noticed this was your very first post - so, Welcome Aboard Furby! You didn't list your state (or country) in your profile. So, you might consider jumping over to Sub-Forum: Select Your Area.... for information (i.e., clubs, hunts, finds, legends, maps, etc.) directly related to your state (or country). You might also consider adding your state (or country) to your displayed profile (SETTINGS -> EDIT PROFILE) - members may have more success helping you (your location may help, etc.)...

2nd - I moved ya from GENERAL DISCUSSION over to ROCKS/GEMS for more exposure. [/FONT]
Welcome to the forum,
Pictures in natural light with good focus and contrasting background help with our efforts here to identify various minerals. Yours are difficult to zoom in on. That being said my opinion for the first stone is that it's either conglomerate, mud stone or sand stone. Your next line of pictures are various types of water worn quartz/chalcedony and sand stone. The last is an metamorphic granite. My thoughts.
