Re: STENO'S PRINCIPLES OF STRATIGRAPHY: ORIGINAL HORIZONTALITY, ETC
It's a simple question Faith, and one you could answer in 5 seconds if you didn't want to avoid it for whatever reason.
Yes? No?
Is a layer of sediment which is made up of particles previously suspended in water, then settled out of the water and then subjected to lithification and thus turned to sedimentary rock "strata" by your unique definition?

I didn't give you a definition, I'm trying to figure out what YOUR definition is. You being willing to answer a few simple questions will allow the *many* of us on this thread who are confused by your inconsistency to sort it out and better understand you.
Below is a VERY clear scenario. If you don't find it clear, ask a clarifying question about the scenario so that I can make it clear.

This isn't complicated Faith, it's the basics of sedimentary rock formation. Claiming that I'm the ignorant one regarding this process while avoiding a perfectly simple question regarding the most basic formation scenario is telling.
The question I've asked is as simple as it gets and yet you act like it's a trap with a thousand hidden exceptions:
A: particles are suspended
B: particles settle to the bottom
C: lithification occurs
A to B to C. Strata or not?

I get more and more confused regarding your fundamental position on strata the more you tell us about it. If "ALL the strata are highly variable in thickness", then how can multiple contiguous layers of strata only be horizontal?
Those two positions are mutually exclusive. Do you not see the conflict? How do you reconcile such?

Regarding Steno, what he means by the word "fluid" is non-solid. Water, air, dust, blowing sand, etc., are all non-solids that he envisioned overlying any sedimentary layer undergoing deposition.

Faith, you would do well to learn and remember that to science and engineering, the term "fluid" does not literally mean "liquid". The easy lookup dictionary definition demonstrates that clearly, while a more scientific definition is even more fluid
quote:
The distinction between solids and fluid is not entirely obvious. The distinction is made by evaluating the viscosity of the substance. Silly Putty can be considered to behave like a solid or a fluid, depending on the time period over which it is observed. It is best described as a viscoelastic fluid. There are many examples of substances proving difficult to classify. A particularly interesting one is pitch, as demonstrated in the pitch drop experiment currently running at the University of Queensland.
Finding a favorite meaning with terms like "horizontal" and "fluid" that suit a particular purpose doesn't help you like you think it helps you, it only backs you further onto rapidly receding footing. Under normal gravitational conditions, particulate solids such as sand, gravel, coal, grain, etc., all act as fluids once their angle of repose is breached and thus can no longer resist shear loads.

Ok, got it. Thanks for the explanation.
And your observation is correct -- either Faith accepts that the thickness of the Coconino varies dramatically which gives her conflicting positions, or she denies the Coconino varies and is in violation of reality.

You do realize that those thousands of square miles of flat horizontal slabs can't actually be flat and horizontal don't you? Imagine how far you could see.

Faith, several times later I've ask a series of perfectly simple A, B, C questions of you in an attempt to understand your position as to the formation of sedimentary strata. You go to extreme gymnastics to avoid answering. I'm going to try another round.
Scenario:
I take an typical household sized fish tank / aquarium.
I measure out enough fine silt to cover the bottom of the tank to a depth of one inch (I do not place it in the tank yet)
I place a small dome shaped rock, 3 inches in diameter and 2 inches tall in the bottom center of the tank
I fill the tank with water.
I mix in the silt while stirring to make sure it is suspended in the water.
I leave it undisturbed until the silt has settled and the water is clear enough that we can easily view the floor of the tank.
Do you believe:
A: that that 1" layer of silt that has settled to the bottom will be draped at all over that rock?
or
B: that the silt will the be butted up to the rock in a perfectly horizontal plane all the way around the rock?
In other words, will we see the top of the dome shaped rock free of sediment or will the entire rock be hidden by the sediment?
Thanks
JB

It was me who suggested a variation to the experiment that included a rock. Instead of a rock use a hard-boiled egg with the small end pointed up and the large end embedded in the sand so that the greatest perimeter is level with the top of the sand. Now slowly sprinkle sand evenly across the water's surface until the depth of sand has increased by a half inch or so. The sand will be deeper and non-horizontal next to the egg.
If I had ever been able to get Faith to address or even answer questions regarding the outcome of such tests, I would have done the experiment(and variations) and filmed them for her. I will get to it eventually as part of my earth science curriculum.
It's such an easy and clear experiment and can be done in a low energy environment (sitting perfectly still) or with medium energy input (say a fan making waves on the surface) or even high energy (a mixing system of some sort). I'm looking forward to working those details and and showing the series.

I'm not thinking of such minuscule tolerances though I'm accused of insisting on an impossible perfection.
And yet every single time we've asked you (and we've asked you a LOT) to imagine what sort of tolerance there was to your 'horizontal" (even when we ask you about FIVE THOUSANDTHS OF ONE DEGREE out of perfect horizontal) you responded with descriptions of just how crazy we where and how you could not believe how out of touch with reality we are.
Admin writes:
I think this will come as a great surprise to everyone. You were pretty strong in your insistence that Steno required strict horizontality with no deviation, and in your insistence that Steno had it exactly right 350 years ago and that geology had gotten horizontality all screwed up since.
Yep -- over and over and over she did this.
Faith writes:
Overall I would expect all deposited sediments to arrive at a horizontal surface no matter what the shape of the foundation it deposits on.
Well, until YOU define what YOU call "horizontal", we can't even imagine what you mean by that statement. That is why we have attempted to get such a definition from you for pages and pages and all we get is retorts and obfuscation.
Faith writes:
Depends on how fluid the sediment is how close to true horizontal it gets,...
Of course it does, that's what we've been trying to tell you - and we've been trying to tell that when it comes to soils, the measurement of just how "fluid" a sediment is is called the "angle of repose".
Here are a few samples of sediment shoveled from the bottom of a lake showing several different consistencies, NONE of which are in any hurry to become horizontal (whatever your definition is).
In a high energy environment, these would disperse into the water and spread out. In a low energy environment, they will not be growing legs and moving themselves to the low end of a lake whether that is a hundred yards or miles away. It's simple physics Faith.
So now that you've acknowledged that by "horizontal', you don't mean perfectly flat, let's return the question in Message 1122 and see if we can't make some progress.
THAT is the question that is being asked of you - if the deep and still bottom of the lake bed were to slope from East to West by .05 degrees, would the sediment form an even layer across the lake bed or would it somehow all magically be displaced to the West (lowest end) of the lake? How about .005 degrees? How about 5 degrees.
Surely you must be able to imagine some minute angle that is close enough to horizontal where the deeply placed sediment just stays were it falls. Conversely you must be able to imagine an angle that is steep enough that WOULD cause the sediment to slip to the deep and and not adhere to the lake bed surface.
What are the limits of these two angles that you are imagining?
Can we get an answer now?
JB

One thing to remember is that the angle of repose in water would be less than in air because of the buoyant force of the water which would decrease the normal force of gravity (as you said, it's simple physics).
Yep. To someone who is knowledgeable of these relationships and understands them, it's rather simple to make reliable predictions. If one refuses to learn, guessing is all that's left.
I think that Faith believes unconsolidated sediments to have no strength at all, but even as it touches down, each grain starts forming some kind of relationships to other grains that create some strength.
I don't know Faith's background, but I suspect she hasn't worked with materials very much. Grouts, mortars, concretes, etc. (hell, just a mixture of sand and water) 'gels' rather quickly achieving a measure of stability. Mix them up and they will again 'flow'. Let them sit for just a few minutes and they bind again. We're not talking 'curing', it's just the irregular shapes of the particles settling into interlocking positions with each other. When grouts are pumped into cracks or bores for soil stabilization, you have to get it moving and keep it moving or the process comes to a grinding halt.
