First one looks a bit like some of the material from the Owyhee Sunset area. Does 2 have any metallic inclusions? Number 3 is brecciated jasper, and from the pieces it looks like it is also from the Owyhee basin. I've seen Owyhee jasp with areas of breccia, but nothing quite that wild.

Number two looks like a type of granite stone...

Please don't be offended but the third pic probably should be considered a conglomerate rather than a breccia. Because the fragments are rounded instead of being angular indicates that it is of sedimentary origin and has been cemented in a similar way as concrete. As far as a jasper from the Owyhee basin sure no problem.

I thought 1 might be wood, 2 granite and 3 some kind of pudding stone- conglomerate.

1 does look kind of woody, doesn't it? Would need a photo of a barky looking edge and then a smooth one.

Because the fragments are rounded instead of being angular indicates that it is of sedimentary origin and has been cemented in a similar way as concrete. As far as a jasper from the Owyhee basin sure no problem. No offense taken, but piece 3 is not a sedimentary conglomerate. This is typical monomict breccia formed by chips popping off the host rock. You often find this re-silicified material directly attached to the host rock from the broken pieces spalled off (due to weathering, tectonic activity, etc.). As to angularity, there are some angular pieces in there, and it isn't always possible to see all the angles and straight lines in a slabbed piece. BTW, I asked whether there were any metallic areas in the second because there are some ore-bearing stones (such as pulsite and Josephine's Crown) that look similar and are cut into gemstones. Difficult to detect metallic flashes in a photo. |

diorite came to mind for the black & white If not metallic as pointed out above, I'll vote for grano-diorite |

#3 is TN puddingstone if it is from TN. They also find identical material in AL, MS, AR and OK They may use different names there. this is a chert conglomerate cemented by limonite. It is messy to cab and hard to tumble but does take a great shine.

rmf is correct about number 3. There was a lot of that material from Tennessee floating around at the rock & gem shows in the Southeastern U.S. back in the 1970s being called "Flint Conglomerate". Later some folks were (and still are) calling it "Tennessee Puddingstone". I think I still have some of it around here somewhere. Best I remember it was sort of soft, at least in areas, but did take a good polish.
