This new understanding was partially pioneered by Carmala N. Garzione (left) of the University of Rochester, who was quick to say “We've always assumed that the folding and faulting in the upper crust produced high elevation mountains.” However, around two years ago, her beliefs began to morph into a new paradigm regarding mountain building. Her more recent comment, “Now we have data on ancient mountain elevation that shows something else is responsible for the mountains' uplift," suggests her changing attitude based on the studies she has made in the Andes Mountains of South America, considered the youngest mountain range, yet the tallest in the Western Hemisphere, and certainly one, she claims, has shown a tremendous and sudden movement upward defying all the old beliefs.
In the past, it was generally accepted by NASA and the National Science Foundation, that the rise of the Andes was 1.4 inches per year of the Nazca plate sliding smoothly under South America, with another 1.3 inches per year locked up at the plate boundary, squeezing South America, and was released every hundred years or so in great earthquakes. About 0.3 inches of motion per year crumples South America, building the Andes. Then, two years ago, Garzione found that mountains, especially the Andes, shoot up in spurts as much as two and a half kilometers (8,202 feet) in 7 million years, as opposed to the 70 million years previous understood. Now, however, that 7 million years is being downgraded to 2 million years.
The problem scientists face, obviously, is that their measurement techniques are minimal at best, since they are trying to measure something that cannot be seen (techtonic plate and their assumed movement) and the height of a mountain growth over millions of years. Now for the scientist, that is really not a major issue, since we are still talking about inches in hundreds of thousands of years. However, the issue then becomes one of exactly how much time are we discussing? If the world is, indeed 4.55 billion years old, then mainstream science is correct and the movement or growth of mountains is so slow by our life-cycle standards, it really doesn’t matter one bit.
Top: a “Blob” forms along the bottom of the
Mantle, these are anchors, keeping the crust from rising and in place; Middle:
the density of the “Blob” or anchor begins to falter, its density buildup is
too heavy to be held by the Mantle or Lithosphere, as the crust begins to rise
slightly; and Bottom: the “Blob” or anchor melts and falls into the
Astenosphere to begin again, and with the loss of weight the crust shoots
upward, as Casione puts it, “like a popsicle”
Consider what we do not know: Despite all the fancy drawings to the contrary, we do not know anything about what is further down into the Earth than we have been able to drill and see for ourselves—the deepest borehole ever drilled to-date is by a Russian project in the far north Kola Peninsula during the 1980s that reached 7.46 miles, or just over 2410 feet (2410.07873)—we have barely scratched the surface of our planet.
The Crust is brown, the top of the mantle is gray—the project is to
drill down to the gray mantel
According to CNN, there is a project
to drill down to the Earth’s mantle, at a project cost of $1 billion. A team of
international scientists plan to drill into the Earth's mantle in an attempt to
answer questions about the origins and evolution of life. The drills are
planned to get through almost four miles of oceanic crust to reach the mantle,
and to a point that begins three to five miles under the oceans to as much as
25 miles under continents. The mantle itself is believed to be 1864-miles thick
through the slowly deforming rock between the crust and the core which makes up
the majority of our planet—and bring back the first ever fresh samples.
Part of this new understanding is the evaluation and measurement of temperatures along the Andes over the past few years concentrating on the Bolivian Altiplano, which is a large, high elevation basin in the Andes Mountains in South America. There Garzione and her team took samples of sedimentary rock that had accumulated between 12 million and 5 million years ago (geologically speaking) from erosion of the surrounding ranges. One type of mineral, carbonate, precipitates from surface water, so the composition of the carbonate is a good indicator of the composition of rainfall.
(Continued in the next post, “Mountains actually Shoot Up in Spurts, Part II,” regarding how mountains have recently been found to have formed sudden and rapid rising based on new understandings of the developing roots beneath the crust that form and act as an anchor until the root becomes too weighty and dislodges, falling into the liquid mantle, allow the earth’s surface to suddenly “bob” upward).

Del.. you said:

I am a bit confused.. Is a mile not 5280 feet?
The dome building at Mt. saint Helens is quite interesting. Since 1980 the dome has been growing like a giant loaf of bread. But in some case the scientist have watched as hardened spines of volcanic rock were pushed up from below.
ReplyDeleteThe 3 hour earthquake at the time of Christ would have been interesting to watch as the Andes rose to their great height during that 3 hour earthquake. Truly a miraculous event, but completely plausible from a scientific point of view.
Del, I think you and Ira will both be interested in the Universal Model found at https://universalmodel.com/ After a massive 27 year research project Dean W. Sessions has published

Thanks DeVon for that information. I'll give it a look.
ReplyDeleteMr. Nirom: Sorry for the misleading information. Somehow my fingers didn’t hit the right keys . It’s what I get for trying to be brief.
ReplyDeleteTo correct: The deepest borehole ever drilled to-date is the one at the Kola Superdeep Borehole (Kolskaya sverkhglubokaya skvazhina) by the Russians in the Pechengsky District on the Kola Peninsula.
The project attempted to drill as deep as possible into the Earth’s crust, with a stated goal of 15,000 meters (49,000-feet) or 9 miles (493.3333 yards). Beginning on 24 May 1970, using the Uralmash-4E, and later the Uralmash-15000 series drilling rig, a 9” diameter borehole was drilled by branching from a central hole with the deepest, SG-3, reaching 12,262 meters, or 40,230 feet in 1989, breaking the previous record of 9,583-metrs (31,440-feet) Bertha Rogers hole in Washita County, Oklahoma. It is still is the deepest artificial point on Earth.
In terms of depth, it is the deepest borehole in the world; however, in 2008, a 12,289-meter (40,318-foot) Al Shaheen oil well in Qatar was drilled, and in 2011, a 12,345-meter (40,502-foot) Sakhalin-1 Odoptu OP-11 well was drilled offshore from Sakhalin island.
On 27 August 2012, Exxon Neftegas Ltd beat its own record by completing the Z-44 Chayvo well. This ERD well reached a measured total depth of 12,376 meters (40,604-feet). However, in terms of depth below the surface, the Kola Superdeep Borehole retains the world record.
DeVon: Thank you.
