It is not as sharp as I would like. I'll have to take more close up photos of the various areas. It looks to me like it once was a void that dark red agate formed in. That was caught in an ash flow tuff that stopped with a shattering event, but the shattered agate remained within an inch or so of each other. The penetrating ash crystallized into plumes, then agate filled most of the remaining spaces.
It is usually obvious if a stone grew from the center out, like a pearl, or from the exterior to the center as in "fortification agate, or from the bottom up as in "waterline agate."
Some of our understanding is clouded by "Old Scientist Tales."
Here is another puzzle in Morrisonite, NOT my slabs. Note something different happened to the bottom two examples from the shattered examples on top. All examples were taken from Googling "Morrisonite Images."

On further review of this image so kindly provided at my demand request
I see multiple events going on. Here is my take on it.
1) burgundy jasper forms 2) burgundy jasper brecciates 3) burgundy breccia is filled in with clear/white agate (can you see it?)
this is held together in some form of mud/clay/gel
4) mud/clay/gel is washed away and then agatized or simply agatized (I offer no opinion on which) probably yellow but maybe red 5) contrasting moss is grown and this solidifies the entire nugget 6) scott wants a 5" cube of this material
Shotgunner Excellent! I'm still puzzled by the wide "stream" that runs through the middle - the quarter is in the middle of it. Does event 6) point to some future event like a spherical development? How did you deduce that? Man, you are good!
Luckily we have the Bruno Jasper to help us understand what happened to some Morrisonite.
Bruno began as spheroids that were "popped open" by water expanding up to 2,000% into steam as cooling and contracting magma reduced the surrounding pressure. As cooling continued, the openings became vacuum chambers.
In other areas the spaces were produced by openings in ledge rock.
in both cases, the chambers were surrounded by highly silicious clay. Blobs of that material was injected into the chambers by repeated pulses by something like Old Faithful repeatedly pressurizing the groundwater.

rockpickerforever: Mike, I can tell ya I buy my tequila in 1.75 liter bottles, lol. None of those little bottles for me. One cannot live 10 miles from the Mexican border and not drink margaritas!

phil: metric booze.... smaller bottle, less booze and higher prices.

Fossilman: Tequila straight up and chase it with a cold beer...LOL

wampidy: Na, tequila only kills the bugs that kill ya. Margarita or tequila shot (no s) are the only drinks that do not give me a hangover. I do not do it very often so one of either gives me a fuzzy nose and makes me gigglier than normal if that is possible.

Shotgunner: I think the correct name for tequila is [Tuh - kill - ya]

Shotgunner: Jean, 10 miles from Mexiko? Really? Ain't it more like 30 miles? lol like that makes a diff?!?!?!?!
Jul 10, 2014 12:19:09 GMT -5
Fossilman: Love tequila..It's the only hard stuff I drink if and when I have any.....
Jul 10, 2014 14:05:36 GMT -5
rockpickerforever: Scott, no it ain't more like 30 miles. Okay, I was a little off. I'm 10.9 miles from the border. I checked the distance on ACME Mapper.

rockpickerforever: Jim and Mike, you really don't have to admit anything... really, lol! Tequila did me in years ago once when playing poker. I couldn't drink it, hell, couldn't even stand the smell of it in a marinade, for at least a year. I got over it, happy to say!
Jul 10, 2014 15:10:33 GMT -5
Shotgunner: I stand corrected. 10.9 miles it IS!!
Jul 10, 2014 16:19:42 GMT -5
Shotgunner: Tequila got me 25 years ago and I still can't stand the odor. For me, this is my new fave.
Jul 10, 2014 16:20:51 GMT -5
rockpickerforever: Well, that makes sense. Scott, didya wear the LOUD sneakers in Japan in case you got lost, or to visually offend the reserved Japanese people?
Jul 10, 2014 16:47:08 GMT -5
Shotgunner: loud sneakers and shirts, of course!
Jul 10, 2014 17:06:16 GMT -5
rockpickerforever: I'm used to seeing the bright shirts, so that didn't even register, lol. But the neon shoes were new to me! Ha!

wireholic: Jean - do you live in National City or Chula Juana? I used to live in I.B.
Jul 11, 2014 17:30:16 GMT -5
rockpickerforever: Karen, I lived in National City from about 1982 or '83, until we bought our current house out in Spring Valley in 1992. Been here since. If you lived down this way, then I' m sure you know where the Spring Valley Swap Meet is? Couple blocks from here.
