Fish based diets cause archaeological dating problems

Fish based diets cause archaeological dating problems | Conformable Contacts | Scoop.it

Marine and riverine "reservoir effect" on radiocarbon dating. Fish, fish diets and hard water environments can cause skewed aging by up to 2000 years (older).

 

Sample:

 

"Hard water contains less Carbon-14 than the atmosphere, because dissolved carbonates are Carbon-14 free. A fish caught in hard water has thus a higher Carbon-14 age than contemporaneous terrestrial samples. If such a fish is then cooked in a ceramic pot, the radiocarbon age of the food crust will be higher than if a terrestrial animal was cooked in the pot.

 

This is known as the “reservoir effect” because the fish’s carbon actually comes from another “reservoir” than the carbon in terrestrial animals from the surrounding area. “Reservoir age” is the difference between the true age and the Carbon-14 date."

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.

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.

Physical Difficulties with Hugh Ross’ Local Flood Model

Physical Difficulties with Hugh Ross’ Local Flood Model | Conformable Contacts | Scoop.it
Hugh Ross is a prominent advocate of progressive creation, day age, and a local flood. Others have critiqued Ross’ flood model from a biblical perspective (Chaffey and Lisle 2008, pp. 81–106; Van Bebber and Taylor 1995, pp. 55–59). For that matter, more than a half century ago Whitcomb and Morris (1961) provided an exhaustive refutation of the local flood model. It is not my intention to review the biblical difficulties with the local flood model here. However, few, if any, have pointed out serious physical problems with Ross’ local flood model. In his recent book on Genesis (Ross 2014) Ross discussed his local flood model in more detail than he had previously, so now is an opportune time to examine his flood model for its physical shortcomings.
YEC Geo's insight:

Here's the thing:  the old earth-evolution paradigm is one model, and the young earth-special creation is another.  Take one or the other, but don't try to mash them up, because they don't play well together.

Kamchatka Tourism

Kamchatka Tourism | Conformable Contacts | Scoop.it
The Valley of Geysers — the volcano canyon of about 2 km width and slightly over 4 km length — is one of the best attractions of the Kronotsky Reserve. About 20 large geysers and many springs intermittently spouting fountains of hot water (water temperature is higher than 95°С) or steam are located in this area. Some geysers spout fountains every 10-12 minutes, some – once per 4-5 hours. Since 1993 the reserve is open for tourists.

 

Experienced travelers say that the safe place in the Valley of Geysers can be distinguished by growing wormwood. Wormwood grows in the place where there is neither overheated water nor other nuisances.

YEC Geo's insight:

Please, please, please can I go to Kamchatka?  This Russian tourist page looks so fascinating.  I want to go to a place where the presence of wormwood shows you where there is no overheated water nor other nuisances!

Genesis in clay

Genesis in clay | Conformable Contacts | Scoop.it
An independent witness to the truth of the Bible, however, was too much for the skeptics. They continued to ridicule the idea of a global flood, and argued that the Genesis account had simply been copied, with embellishments, from the Gilgamesh epic. Another cuneiform tablet, however, found less than thirty years later, was to make such a claim wholly unsupportable.
YEC Geo's insight:

I love archaeology almost as much as geology.  This item describes the controversy over a non-Hebrew account of a world-wide flood.

Flooding in Chilean desert region

Flooding in Chilean desert region | Conformable Contacts | Scoop.it

"Flash floods in a normally bone-dry region of northern Chile killed six people and left 19 missing, officials said, prompting the government to declare a state of emergency and send in the army. The downpour began late Tuesday in the Atacama region, home to the world's most arid desert, and lashed the area for hours, turning riverbeds that had been dry for years into torrents."

Orbital Ice Age Theory Melts

Orbital Ice Age Theory Melts | Conformable Contacts | Scoop.it
Orbital cycles do not cause ice ages, a new study suggests. Instead, the whole world experienced an ice age at the same time.
YEC Geo's insight:

Yes yes yes yes yes.  Let's start questioning Milankovitch cycles rigorously.  The idea that sedimentary layers can be correlated with precessional variations of distance from the sun is full of wobbles (sorry, bad pun).

 

The Geology article referenced here begins: "Here we address a long-standing puzzle of ice-age climate called the "fly in the ointment of the Milankovitch theory." "  Good job--keep those articles coming.

Exploring The Last Major Colorado River Tributary Without A Dam To Get In Your Way

Exploring The Last Major Colorado River Tributary Without A Dam To Get In Your Way | Conformable Contacts | Scoop.it
There still remains, in this heavily developed country, a place where a river runs free, unfettered by a dam and surrounded by wilderness. Look towards northwestern Colorado and northeastern Utah. That’s Dinosaur National Monument, with the Green and Yampa rivers.
YEC Geo's insight:

A tour company's infomercial on a fascinating stretch of river in the American West.  Of interest because of its mention of a 1965 rockfall area that's still causing anxiety for rapid runners (see this article here:http://www.nps.gov/dino/planyourvisit/2012warmspringsrapidrockfall.htm )

 

Even photos from 1865 show rockfall scars on the cliff face pictured above.  If this canyon is really tens of thousands of years old, why isn't the river channel completely blocked?

 

Also worthy of mention are potholes perched atop cliffs hundreds of feet above the river.  It's my understanding that potholes are erosional features formed by fast-moving water.  What are they doing so high above the river channel?

 

One last comment.  How did that river erode that cliff face to be so sheer and straight?

Suicide By Drought

Suicide By Drought | Conformable Contacts | Scoop.it
Most of China’s most important rivers originate in the plateaus of Tibet and the surrounding mountain ranges, an area known by scholars as the Third Pole because of its plentiful ice. The rivers flowing from the Third Pole -- among them, the Mekong, the Yangtze, and the Yellow River -- traditionally satisfied the majority of China’s water needs. But those waters, along with China’s other supplies, have been steadily disappearing. Since the 1950s, 27,000 rivers have vanished from China. China has only seven percent of the world’s freshwater to meet the needs of about one-fifth of the world’s population.

Perhaps this more-or-less anatomically modern sponge should encourage evolutionary scientists to question their presuppositions.

Raindrop imprints and the location of the Flood/pre-Flood boundary

Raindrop imprints and the location of the Flood/pre-Flood boundary | Conformable Contacts | Scoop.it
Since rain did not fall at least until after man was created, as clearly stated in Genesis 2:5,6, and possibly until the Flood, raindrop imprints indicate that the sediments were laid down either between Creation Week and the Flood or during the Flood. Given the fact that Precambrian sedimentary rocks were often deposited in deep troughs or basins and are very thick, the time between Creation Week and the Flood is unlikely. That leaves only the Flood, which means that even Archean sedimentary rocks are from the Flood. It also means that Precambrian sedimentary rocks are not a record of Creation Week activity.
YEC Geo's insight:

An interesting logical argument.  Makes sense to me.

How Rocks Can Look Older Than They Are

How Rocks Can Look Older Than They Are | Conformable Contacts | Scoop.it
The reliability of the oldest zircon ages, which include some reversely discordant analyses (i.e., with U–Pb ages older than 207Pb/206Pb ages), has been questioned based on evidence from ion imaging for disturbance of the U–Pb system. This is important because 207Pb/206Pb ages are generally considered to be more robust than U–Pb ages for older zircons. However, if radiogenic Pb has been decoupled from its parent U and not locally incorporated into the crystal lattice during an ancient geological event, when radiogenic 207Pb/206Pb values are significantly higher than at present, reverse discordance and spuriously old 207Pb/206Pb age estimates may result.

Not so cool:  It's not a substitute for Google Earth.   You can only pan out or in to a limited degree, so to go from Texas to Timbuctoo, for example, would take a lot of clicking and dragging.  Best way to get to a place is to type it in the search box.  No 3-D view also. And if there are a lot of clouds when the image was taken, they'll obscure the landscape.

The P–38 Lightning was one of the deadliest planes to come out of WWII. Powered by twin Allison V–12 engines, it had one 20 mm cannon and four .50 calibre machine guns in its nose. Operational from 1941–49, the nickname given to it by German pilots, on account of its double tail, was Der Gabelschwanz Teufel (the fork-tailed devil). They are a highly prized collector’s item; only five were believed to be flying at the time the Lost Squadron P–38 was salvaged —under c. 75 metres (250 feet) of solid ice!

One would think that after over 200 years of uniformitarian thinking that the origin of continental basins would be known, but this is not the case. One of the main problems is the failure to understand why the basin subsided to collect all the sediments.
