Geologists quantify, characterize sediment carried by Mississippi flood to Louisiana's wetlands

Geologists quantify, characterize sediment carried by Mississippi flood to Louisiana's wetlands | Conformable Contacts | Scoop.it

"The spring 2011 flood on the Mississippi was among the largest floods ever, the river swelling over its banks and wreaking destruction in the surrounding areas.  But a University of Pennsylvania-led study also shows that the flood reaped environmental benefits—transporting and laying down new sediment in portions of the Delta—that may help maintain the area's wetlands."

YEC Geo's insight:

 

One of the interesting findings of the study:

 

"...the flood sediments had higher ratios of centric, or round diatoms, to pennate, or rod-shaped diatoms, than the older sediments.

 

The prevalence of round diatoms in flood sediments makes sense, as these species tend to float in the water column and would likely have been derived from the flowing river water that inundated the wetlands during the flood.

 

This ratio, the researchers believe, may serve as a reliable signature of both recent and historic floods—a useful indicator if geologists wish to examine deeper sediments for evidence of floods that occurred years or even centuries ago."

Raison d'etre

Raison d'etre | Conformable Contacts | Scoop.it

In geological terms, a contact is the place where two different types of rocks come together. This ezine is a place to find content from my favorite web sources on the the creation-evolution issue, with a focus on the subject of geology.  Just as the layers of a rock can be composed of many different materials, so my sources often differ in their assumptions and in their views on the issue, but their common intersection is the belief that this is an important subject.

 

(Image source:  Glyn Baker, http://www.geograph.org.uk/reuse.php?id=167895)

YEC Geo's insight:

While my interests are wide-ranging, as even a cursory glance at this site will show,  a subject of great personal interest to me is the preservation of biological material in fossils presumed tens to hundreds of millions of years old.  In my view, the increasing pace of discovery of such material is one of the strongest evidences in support of a young age for the earth.

Travels in New Zealand: to Nelson via Pancake Rocks | Conformable Contacts | Scoop.it
On the way to Nelson two days ago, we passed through Paparoa National Park on the west coast of the South Island, one of New Zealand’s smallest national parks. It’s famous for its limestone geological formations, nearby blue penguins (I didn’t see any) and the rock blowholes, where the sea violently enters the caverns it’s carved, sending up huge plumes of spray.

Massive erosion on California's Oroville Dam

Massive erosion on California's Oroville Dam | Conformable Contacts | Scoop.it
When they eventually shut off the flow, the immensity of the erosion was astounding (figure 4). Half way down the spillway the water had excavated an enormous plunge pool—140 m (450 ft) wide, 75 m (250 ft) long, and 40 m (130 ft) deep. Beyond that, most of the concrete structure had been washed away.

Algae to oil

Algae to oil | Conformable Contacts | Scoop.it
It has been widely believed for decades that ‘fossil fuel’ oil and gas took millions of years to form from algae and plants (and other buried organic material—see box), after being slowly trapped in rocks and subjected to the earth’s heat and pressure over eons.
Heat and pressure suffice to form oil in ultrashort time periods

However, we now know that the millions of years are unnecessary.

8 clues that you should NOT hike Angels Landing

8 clues that you should NOT hike Angels Landing | Conformable Contacts | Scoop.it
For years we have resisted posting this hike because of its proven risks. In recent memory, at least six people have fallen to their deaths while attempting to ascend this lofty massif. It makes me queasy to imagine that the next person's body could be found clutching a copy of our Hike of the Week.

But here's the deal: Angels Landing already is the most popular hike in Zion National Park. People will go no matter what we print, and from what I saw, many of the hikers don't really know what they're getting into.
YEC Geo's insight:
One of the most extreme hikes available in the National Park System.  I got to the beginning of the chain, which is back behind the lady in the picture, but I couldn't bring myself to go any further.  The article explains why so many people think it's worth it to continue.

Microfossils? Maybe. Oldest? Who knows? | Conformable Contacts | Scoop.it
But let’s suppose they are fossils, and let’s suppose they really are somewhere between 3.8 and 4.3 billion years old. If so, then the case for the naturalistic origin of life just got weaker.
more...
Brian Chew's comment, March 8, 10:28 AM
I was very intrigued by this article as this article shows many evidences that scientists give to prove that the metamorphic rocks are microfossils. However it also shows an expert's opinions on it, as he states that although it is true, biological processes could cause the formation of these "microfossils", non-biological processes could do the same. Furthermore, this even happened once with the meteorite in 1997, where people thought life was possible in mars due to some compounds they found on the meteorite, which could be produced by biological processes. However, of course, it was proven that it was wrong and that it was instead non biological processes that caused the formation of those chemicals. This means that the possibility of the rocks not being microfossils are also quite high. However, assuming they are microfossils, this means that the naturalistic origin of life just got a lot weaker, which could shock many. However, this is a very interesting subject to talk about and i hope they could find out the truth soon.

The Curse of the Bahia Emerald, a Giant Green Rock That Wreaks Havoc and Ruins Lives

The Curse of the Bahia Emerald, a Giant Green Rock That Wreaks Havoc and Ruins Lives | Conformable Contacts | Scoop.it
Over the past 10 years, four lawsuits have been filed over the Bahia emerald. Fourteen individuals or entities, plus the nation of Brazil, have claimed the rock is theirs. A house burned down. Three people filed for bankruptcy. One man alleges having been kidnapped and held hostage. Many of the men involved say that the emerald is hellspawn but they also can’t let it go. As Brian Brazeal, an anthropologist at California State University Chico, wrote in a paper entitled The Fetish and the Stone: A Moral Economy of Charlatans and Thieves, “Emeralds can take over the lives of well-meaning devotees and lead them down the road to perdition.”

I too took a bad spin in the emerald’s orbit, pouring endless time into reporting this story, only, for a while at least, to become more confused rather than less.

Junk DNA and Evolution

Junk DNA and Evolution | Conformable Contacts | Scoop.it

"However, while reading Naturalism and Its Alternatives in Scientific Methodologies, I learned about another argument against the idea that evolution doesn’t depend on junk DNA. It comes from evolutionist Dr. Dan Graur, who says quite plainly:

"If ENCODE is right, evolution is wrong. (p. 234 of Naturalism and Its Alternatives in Scientific Methodologies)"

Even though I am a creationist, I would never make such a strong statement, but Dr. Graur thinks it is obvious. Why?"

From Where Did the Earth’s Water Come?

From Where Did the Earth’s Water Come? | Conformable Contacts | Scoop.it
Secularists believe the Earth condensed from clumpy matter flung out of the solar nebula 4.56 or so billion years ago. It was thus originally a hot molten blob that cooled. They used to suggest that most of the water came from inside this cooling Earth, but not enough to fill the oceans we have on the Earth’s surface today. A once popular theory was that comets (which are essentially large, dirty snowballs) collided with the Earth and deposited their water on its surface.

Fossilized mating insects demonstrate instant burial

Fossilized mating insects demonstrate instant burial | Conformable Contacts | Scoop.it

"The earliest record of fossilized copulating insects has recently been unearthed in China (see figure 1) in sediments from the Middle Jurassic. While much is known of the reproductive behaviour of extant (still in existence) insects, examples of fossilized mating individuals (i.e. showing ‘behaviour’) are very rare. Of 33 reported cases in the entire insect fossil record (e.g. fireflies, mosquitoes, plant hoppers, leaf hoppers, water striders, bees, and ants), 27 were preserved in amber (fossilized tree resin), with only six found in compression fossils, including the one examined here. This new find replaces the previous oldest specimen of a pair of non-biting midges (true flies) discovered in amber from the Early Cretaceous."

YEC Geo's insight:
It was mind-blowing to learn that there are 33 reported cases of fossilized mating insects. Not only did they have to be buried in flagrante delicto, but the preservation method had to lack destructive energy. The first condition invalidates slow gradual burial, the second invalidates a flash flood-typical current of moving water that would tear the delicate insects apart.

Clearly more work needs to be done here on the depositional conditions that would satisfy two seemingly contradictory requirements.

One possible hypothesis is that the insects (and other similarly preserved fossils) were killed by catastrophic poisonous outgassing. That would have dropped them in their tracks, so to speak. Then steadily rising sediment-laden water could have buried the corpses. See here for a modern instance of mass biologic death by outgassing: http://sco.lt/547Lw9 Explains a lot of things, but the geographic scale would have to have been much larger than what happened in Cameroon.
