Great series. Thanks, 1dave

I just edited the first post and will have to make more corrections. With new information about silica gels I'm forced to re-think -

Agate deposited by high temperature water grows from the outside walls to the center

- "Fortification Agate."

Agate deposited by cool water forms flat layers on the floor of voids

-"Water Line Agate."

I'm now thinking quantity of gel water rather than temperature is the controlling factor between waterline and fortification.

I'm a ROCKOLOGIST !

So basically the viscosity?

Yes. At room temperatures the gel is evolving into needles, spheres, various submicroscopic crystals.

Hollows in rocks - whether they be amygdaloids, lithophysae, or any other voids below the water table is at some time filled with water.
With earthquakes much of the water is converted to silicic acid that enters the voids.

If the void is filled the dimers, trimers, etc. THEY begin attaching to ALL the walls.

If only a small amount enters, they can only attach at the floor.

IF the next fluid is of high pH some of the material is dissolved and re-deposited as the pH lowers.
