Rock choppin Rios again

The purple may be rarer, but I really like that first slab!

Why is it orbicular in agate but poppy in jasper?

Oh Fork! I made a whole long explanation and lost the dang post *L*. Basically to me, it's a matter of two things One is size, kind of like pisolite and oolite. Poppy/flowering types of jasper tend to have larger poppies where the radiating crystal structures are quite visible. Orbicular types tend to have tiny orbs like concentric circles where the crystal structure is not visible. The second thing is the dominant pattern. Are the little circles that you see most like this:





Or is it flowers you see, like this:





And, for the record, most poppy/ orbicular sites have both especially Guadalupe and Hornitos






And some have snowflake type patterns too:





That confusing enough for ya? *L*.....Mel
