Salt of the Earth (on salt domes and beds)

No you didn't.Dietz and Woodhouse say nothing of the sort.What they say is what I've already said repeatedly --- that such deposits are almost certainly not produced by complete evaporation of the water in a basin. So they write: "Complete dessication, which requires zero precipitation and zero inflow, is an asymptotic end point never achievable in reality", and suggest: "Undirectional inflow through a coral reef barrier dam at the Gibraltar portal is offered as possibly causing brine saturation in the Mediterranean". Which produces a slow continuous process of evaporation which is never complete evaporation; which is just what I've been talking about. I mentioned it specifically in message #60 of this thread, quoting a message already posted on the other thread about salt: "Slow evaporations of vast amounts of water" is precisely what Dietz and Woodhouse envisage. Nowhere do they mention hot water coming out of the Earth's crust.Edited by Dr Adequate, : No reason given.

Up to a point, but now I'm not sure if in that photograph I might only be seeing the darkest and hence most distinct layers.Maybe some looking-stuff-up is called for.Edited by Dr Adequate, : No reason given.

Thanks. I always learn something from these threads.

This makes me a bit puzzled. How can a 'global' flood cause so much local variation in mineral concentrations and indeed even composition by locality. Are you familiar with the Borax mining near the appropriately named town Boron, California?Try this:

quote:

---

The major ores of boron are a small number of borate (boron oxide) minerals, including ulexite (NaCaB5O9.8H2O), borax (Na2B4O5(OH)4.8H2O), colemanite (Ca2B6O11.5H2O) and kernite (Na2B4O6(OH)2.3H2O). These minerals form when boron-bearing waters percolate into inland desert lakes and evaporate, leaving layers of borates, chlorides, and sulfates. These minerals are referred to as evaporite minerals. Very large deposits of evaporite boron minerals are found in the United States (especially California), Turkey, Chile and Argentina. Less-important deposits occur in Iran (formerly called Persia), and elsewhere.

​

In addition, boron silicate minerals are mined as boron ores in China, Russia, and a few other countries.

​

Turkey, the United States and Russia are the largest producers of boron minerals. Argentina, Chile, and China have important ore production, and five or six other countries produce minor amounts. The U.S. production is all from the deserts of southeastern California.

quote:

---

The minerals to crystallize first on desiccation were sodium carbonate decahydrate (Na2CO3.10H2O) and Borax (Na2B4O7.10H20), and this would occur in the winter. During the following summer the Na2CO3.10H2O would melt, and carbon dioxide from the atmosphere and from biological action would react with the Na2CO3 to cause Na2CO3.NaHCO3.2H2O, also known as Trona, to replace the Na2CO3.10H2O. The next major mineral to crystallize as desiccation continued was sodium sulfate decahydrate (Na2SO4.10H2O). This would also crystallize in the winter but during the following summer it too would melt and the released Na2SO4 would recrystallize as Thenardite, Na2SO4 without the hydrating water. When there was a sufficient amount of potassium, it would crystallize as Glaserite (K3Na(SO4)2) at the same time as sodium sulfate decahydrate. Over time much of the Glaserite has recrystallized as the rare mineral Hanksite. The final major mineral to crystallize was Halite (NaCl) and this occurred near the end of desiccation. This depositional sequence is easily observed in the vertical stratification found today in the highest saline mineral bed, the Upper Salt, where Halite makes up the top 20 to 25 feet, Borax and Trona are next to the mud at the bottom of the salt bed, and the sulfates (Hanksite and Thenardite) are in between.

Source: geologyAnd what about those 1500 feet of repeating layers of halite, anhydrite and, and gypsum below my feet and nearby in over 260,000 correlated layers in the Castile formation. Where is the Borax and Hanksite? How did these obviously seasonal layers occur in a matter of several hours?

quote:

---

The thickness of each couplet in the 260,000-varve sequence (a total thickness of 447.2 m, 1467 ft) has been measured individually and recorded and provides the basis for subdividing and correlating major stratigraphic units within the basin. The uppermost 9.2 m (30.3 ft) of the Bell Canyon Formation contains about 50,850 varve couplets; the Basal Limestone Member of the Castile about 600; the lowermost anhydrite member of the Castile (Anhydrite I) contains 38,397; Halite I, 1,063; Anhydrite II, 14,414; Halite II, 1,758; Anhydrite III, 46,592; Halite III, 17,879; and Anhydrite IV, 54,187. The part of the Salado collected (126.6 m) contains 35,422 varve couplets. The Bell Canyon-Castile sequence in the cores studied is apparently continuous, with no recognizable unconformities.

​

The dominant petrologic oscillation in the Castile and Salado, other than the laminations, is a change from thinner undisturbed anhydrite laminae to thicker anhydrite laminae that generally show a secondary or penecontem-poraneous nodular character, with about 1,000 to 3,000 units between major oscillations or nodular beds. These nodular zones are correlative throughout the area of study and underly halite when it is present. The halite layers alternate with anhydrite laminae, are generally recrystallized, and have an average thickness of about 3 cm. The halite beds were once west of their present occurrence in the basin but were dissolved, leaving beds of anhydrite breccia. The onset and cessation of halite deposition in the basin was nearly synchronous.

How can the same physical mechanism (global flood) create several different types of mineral percentages or indeed even existence at different locations? And remember this does not only apply to evaporites but also virtually all mineral concentrations and different mineral compositions that geology directly observes at different places on the surface or indeed down to the Precambrian throughout the earth's crust.I used to collect rare minerals and I have been to all of these locations and have seen the facts, what is your explanation for my so-called hallucinations?Remember, if you invoke magic or Loki, then automatically you admit science does not support a global flood ca. 4350 BCE.

You bet, prefer dry times, may get some crystals if lucky.Sorry, didn't notice before, have been busy with the semester wrapping up.Also, still working at the plant in Snyder? The daughter is a junior in Chem Engineering (not bad for 18, but then again she came within one class of receiving her AS before the HS diploma). Is the invite still valid?Apologize for the proud parent thing, can't help it.{ABE} oops, just realized already replied to this post a while back {/abe}Edited by anglagard, : No reason given.
