several specimens

dt specimen 1 in photo gallery was found by me in the Algerian Sahara. It was very common, the unusual feature of this is the texture, which is wrinkled, looks kind of like brain matter. Any thoughts on what it is?

dt specimen 2 is a banded quartz (agate) found near Pearce, Arizona.

dt specimen 3 and 4 are two views of what I think is an agate. This was found in a load of gravel delivered for my yard, have no idea of the origin.
