Common stones that I tumbled.. what are they?

[blueskyminer]

I found these out in the desert while picking up small pieces of petrified wood. Tumbled them with the PW and they ended up fairly colorful. Dumb question I know but what are they? Thanks in advance.

It looks very similar to Alibates flint from the Texas panhandle. Also looks a bit like Tecovas jasper. I know it's not...but it does look very similar. Alibates is silicified dolomite. I'll be curious to see what the experts think. Gary

Appear to be a mixed jasper/chalcedony. You were looking for petrified wood so that would be common in such an area. Tumbled nicely though.
