Quartz or Quartzite.

Maybe Chert.

Again, it would really help your chances to get an ID if you included a general location and size. ;)

This is a piece of calcite that commonly forms along minor faulting within Upper Cretaceous formations in Texas. Sometimes it's referred to as "slickenside" calcite.

Mineral, so - not a fossil.

Keep your eye's peeled.

My specialty. Yes it's a nice piece of Quartz with some calcite mixed in. The orange color is iron stains from the deposit. I've notice a lot of quartzite in lower regions of North America with iron deposits and stains.

Nice find. Where did you find it?

In this case, Mitch, it is just calcite with varying amounts of intrusive soil and other impurities. These are common in Texas and they are not formed in association with quartz. ;)

With some slickensides it feels much easier to run your finger down them one way than the other, just like stroking a dogs fur. When found in-situ in geological formations this can show the direction of movement along a fault line, the movement being in the direction that feels the smoothest.
