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.
