Moab, Utah finds - what are they?

[crazysanman]

Hello all,

I recently went on a several day rockhounding camping trip in the Yellowcat Flat area of Utah, northeast of Moab.  I was mainly looking for agate.  I thought I could identify it, but I can't find pictures of material similar to what I collected in Google image searches so I may have targeted the wrong stuff.  I've got pictures of different specimens to post.  I'm going to put each type in a different post to make it easier to comment on.  Thanks in advance!  First, here are two pictures of some of the material as I found it on the desert floor.

Is this stuff agate? I found it ranging from almost clear to milky white, gray, blue, and red.

This stuff was opaque, ranging from red to orange to brown to black. Is this agate or jasper, or something else entirely?

I found this jutting out of the ground in a few spots. It's delicate and reminds me of mica, but it's definitely not the mica I used to find on the east coast.

I tried my hand at finding fossils across 191 from the entrance to Arches National Park and didn't have any luck, but I found these in the parking area at the base of the red sand hill. The white runs through the rock, not just on the surface.

Agate?

Is this petrified wood?

I don't know what the white mineral is in these,  or anything else for that matter.

This one has a lot going on. What are the main minerals in This?
