Bought some really nice rocks at Cactus Joe's... one of them is a really adorable poppy 'nodule'? Can't figure out which it is tho, so hope one of you poppy experts can tell me... is this Hornitos Poppy? Also... what could this be? Thanks:)!

Daniel, that does look a lot like it! Especially the last pix. Also, if it's from Az, it's close to Nevada too:).

Any chance you'll slab it? Not the typical Morgan Hill Poppy, but it does come in red and dark; most is catsup and mustard.

I don't have a saw... so I can't slab anything. That's why I mostly get already slabbed rocks:). I bought 2 rocks that size and that's all, because they were so pretty. Here's the other one: Other side: I THINK this is azurite/malachite/quartz

I'm on the fence about your poppy. could it be bone?

It DOES look a lot like that Don... and given the proximity, I'll bet that's exactly what it is!
Have you slabbed any?
I'd still like to know which poppy the first one is... where's Mel or Lowell:P?

I'd agree the second example could be lysite which shows a lot of variety. I don't think the poppy is Hornitos. Looks more like some of the material found along the coastal zones from north of SF Bay to the Olympic Peninsula but then, poppy from all the areas, has all kinds of variations from the standard types. It is interesting that it is mainly red with darker areas, which is more common in Hornitos and that north coastal zone. Morgan Hill tends to have golds or yellows as do many of the interior Coast Range poppy varieties from California....Mel

Mel, do you mean some of the Olympic Poppy Jasper?

Daniel, Yeah but the Olympic Poppy jasper is kind of a local name for the material, Similar deposits occur north of SF Bay and all up the west coast of California, Oregon and Washington. Identical material occurs as nodules up by Hornitos too as that's the same Jurassic formation even though it's in the Sierras I should have mentioned there's also some similar looking stuff out of Mexico that has the flower jasper look too that's more of a silicified rhyolite. Would be easier to ID if it were slabbed or face cut..Mel

Thanks Mel:).
I looked up some of your old pix and it resembles but isn't identical to some of your hornitos... but as you mentioned, many of your pix are missing, so couldn't tell for sure. I know it would be easier to ID if cut... but it's such a cute round rock, I don't want to cut it:).

More I look at it, the more I'm thinking it's the Mexican material. When I lived In Commiefornia, I used to deal a lot with Rons Rocks at Camarillo.. He still sells on E-Bay as Rle, and he had quite a lot of that material he'd bring to shows..Mel

Helen: Could be different stuff but like all Poppy type stuff, the Mexican material does vary quite a lot too. It can be red , orange or yellow/orange. There is also poppy from the Rio Grande gravels but it is very closely related to the Mexican stuff and often has lacy designs along with the poppies in portions of the patterns. Again, hard to differentiate from a rough specimen unless it falls into one of the main categories from a known location....Mel

That Mexican poppy clearly has hematite in it. It is also a rhyolite and not a true jasper. Very different from yours I think.

Daniel, True, but many specimens of the Mexican material are transitional, being so infiltrated with silica as to be very jasper like in hardness and porosity even though they are actually rhyolite or began as such. Hematite is a big component in all the Hornitos poppy jasper types and in most all those coastal types from the west coast and some of the Hornitos Jasper types appear to be silica replaced rhyolite, even having those hexagonal patterns you see in some bird's eye rhyolite. As we've discussed before, the whole poppy jasper origin thing is very confusing. The right hand side of the right hand example in this pic has remnants those bird'seye type patterns ...Mel

Well, I had thought that all the rocks at Cactus Joe's was from the US... mostly because all their labeled bins were all US locations (some of which I never saw before). Also, they had no obviously non-US rocks like OJ, charoite, bumblebee, etc.
HOWEVER, I think I got some Imperial, so maybe they have Mexican rocks (or my imperial isn't imperial but something US). Still trying to figure out WHAT I got, since I don't recognize hardly any of the rocks. That's intentional, since I didn't want to buy rocks I already had:P.
I tend to think it's a US poppy, simply because they had a lot of old US rocks like Deschutes, Biggs, morrisonite, rhyolites, hickorite, etc. Was just wondering which one it might be.

Could very well be Helen. Rock types really know no boundaries. Same geological conditions= same type of geological formation. Some examples of poppy/orbicular jasper from California can be identical to that from Mexico, Madagascar, Arizona, Washington, Great Lakes Iron Ranges etc and the red on dark background type poppy is one of the more abundant color combinations as hematite is a major component in many many jasper types but especially, poppy jasper from Western North America. After, it's iron oxides that make the yellow or red colors in jasper....Mel

Mel, I agree about the blurring of rhyolite and jasper when they get highly silicified. My remarks were more specific to the link Helen posted to the Mexican Poppy offered by Rons Rocks. There was a very definite blue-hematite background. I should have been careful not to speak so generally. The background in Helen's rock does not look like hematite.
