In structural geology, the study of
deformation of rocks and its effects is studied. Here we see Geologic Folding of solid rock
If not negligible, the stress applied breaks the rock, which is called brittle deformation, causing fractures in the rock. Temperature changes can also cause rock to expand and contract, which leads to fracturing or brittle deformation.
Examples of brittle deformation where the
rock has been fractured rather than bending
Fold occurs when one or a stack of originally flat and planar surfaces, such as sedimentary strata, are bent or curved as a result of permanent deformation. Synsedimentary folds are those due to slumping of sedimentary material before it is lithified. Folds in rocks vary in size from microscopic crinkles to mountain-sized folds. They occur singly as isolated folds and in extensive fold trains of different sizes, on a variety of scales.
In many
places on the earth, like at the Grand Canyon, thick rock layers have been bent
and folded together without breaking. So, how does this happen? How do you bend
rock? Earth Scientists who believe the earth is
very old, claim that it took millions of years for these rock layers to be
formed. They say that the layer on the bottom of the Grand Canyon is millions
of years older than the layer on top, yet these sediment rock layers are hard
like concrete and concrete cannot be bent without breaking—so how do these
ancient rocks bend and not break?
Another comment made was: “if your proposal is to have sea levels inundate half of the South American continent, that is known to be incorrect.” The sad thing is, so much has been learned in recent years that this area of South America being under water is now an accepted fact among geologists, but people who have stopped learning are simply unaware of it. In fact, just about every geologist who has ever written regarding South America states this well-known fact, that it was under water until the Andes came up, as we have written here many times, quoting specific scientists, etc. Even Darwin made the same personal observation in the Andes mountains between Santiago, Chile and Mendoza, Argentina.
The difference, of course, is in timing. In fact, in the past decade, geologists have found that the Andes came up not only much later in time (closer to our time) than previously believed, but much faster than previously thought. They still talk in tens of thousands of years, but the point is, what they once thought was absolute they are now realizing is not, as they had always thought, as new studies and new techniques show old information to be inaccurate.
Yet, this Mesoamericanist, without hesitation, discards all of that out of hand because it simply does not meet that person’s pre-determined viewpoint of Mesoamerica being the Land of Promise. Of course, to do so all he has to do is hide behind his so-called science—but as stated above, that hiding place is getting smaller and smaller as newer and newer information becomes available through more modern knowledge and studies.
Let’s take a look at some ideas that are only now becoming accepted facts. David Allen, Ph.D in groundwater physics at the University of New South Wales, Australia, has worked for ten years throughout the world as an exploration geophysicist for an international geophysical company, has shown clear evidence that the rocks could not have been hard and brittle before they were folded, yet we were all taught in school that folded rocks were deformed over millions of years of gradual application of heat and pressure.
However, most university teaching on the matter ignore the reality, even during study excursions that show there was no fracturing during folding of rock despite the rock having to have been aged and brittle at the time it folded. Instead, the lectures claim the rock must have been deformed while the sediment was still unconsolidated and saturated with water. This, even though students all realize that the rock could not have been brittle when it was folded so tightly. It must have been soft and plastic. If the rocks had been hard and solid before they were deformed, they obviously would have fractured, not folded.
Soft sediment folding (top: white arrow and bottom: red line close-up)
in the Turon River area of New South Wales, Australia, about 100 miles west of
Sydney. Note the gentle folding of the rock with no fractures. As can be
pointed out, there is no evidence that the rocks had ever been subjected to
much heat or pressure—instead, it is clear that this bending took place at
normal temperatures
