Why is the correlation of rocks difficult within Archean and Proterozoic rocks?

So, we'll never know what type of rock used to be there or what fossils it may have held. This excellent new resource contains 40 articles taken from the last 40 years of Creation magazine with some updated, as necessary , covering a wide range of origin-topics—all bound together in a beautiful, hard-cover package. It is likely that they were laid down after the initial, highly catastrophic onset of the Flood and represent relatively calmer depositional conditions over a wide area that did not undergo deformation, possibly between Day 40 and 150. Southward was a shallow sea covering the remainder of the continental block. In many cases only plutonic rocks are suitable for isotopic dating, so that they also serve as geochronological markers denoting definite stages in geological history. Changes of temperature caused the granitic rocks to flake off at the surface, gravity and moving waters carried the loosened rocks down the slopes, rolled them together, broke them into smaller and smaller particles, carried them to the sea where they became sediments that muddied the seawater.

It is entirely possible that forensic analyses based on current providential constraints i. All rocks and minerals contain tiny amounts of these radioactive elements. You can test out of the first two years of college and save thousands off your degree. These use radioactive minerals in rocks as geological clocks. The rocks started to flake off and break up, and erosion was initiated.

Precambrian Era

Neither side is questioning the reliability of the Bible. Furthermore, there is evidence of significant tectonic activity in the Precambrian such as deep basement rifts and basins. These dating methods are easily manipulated and are not independent. Like any other idea, especially those in their early stages, this concept needs careful scrutiny from presuppositional, logical, and empirical points of view. In other words, there is no simple compression conversion that will fit the 4,567 Ma of secular history into the 6,000 years of biblical history, of which only 377 days the Creation and Flood are significant geologically.

This in turn suggests that the uniformitarian timescale is not acceptable as a relative chronology of the Flood, or to the revolutionary idea that time is not the key to interpreting the rock record. Although this principle is generally applied to relative dating it is also the basis for evolution. The evolutionary scheme is not at fault of course! But, the shales are all deformed and folded up. What happened to the mysterious Ediacarans isn't clear. Natural history is unrepeatable and unobservable. The fifth is the tectonic discontinuity of greatly increased activity representing the onset of the Flood.

Carbon 14 is best for dating fine. All sides of the debate agree that the 'billions of years' ages derived from radiometric dating are wrong, and that the Bible's timeframe is right. Laurentia, the North American craton, is one of the oldest and largest. The Precambrian covers almost 90% of the entire history of the Earth. Another issue is that the various dates on Precambrian crust would have been affected by events in the Flood, including further accelerated radiometric decay and may not mean anything as far as a timescale for Day 3.

One assumption is that the chronostratigraphic timescale is reliable. He also concludes that the post-Flood boundary is in the Pliocene, which is fairly close to my assessment of the situation. These other conditions and their effect on this boundary should be explored. Marvin Lubenow documented this problem. In the course of a long time, as layer upon layer of sediments were piled one on another, they were compressed, cemented, and consolidated into rock which we call sedimentary. Life has not changed much during the last two billion years, but the few changes are significant.

These huge masses of land formed by collisions of the many, many islands made by volcanoes during the Archean and most of the Proterozoic eras. If an igneous or other rock is metamorphosed, its radiometric clock is reset, and potassium-argon measurements can be used to tell the number of years that has passed since metamorphism. Thus, advocates of relative dating must know when to convert old dates to years of non-Flood history, and also to days of Flood history. We can speculate in a forensic manner about the rock record, but the boundaries of our speculation must be those of Scripture. Other belts contain accreted Early Proterozoic island arcs and associated intraoceanic deposits. Fission track dates on two tuffs in the middle Cambrian Tapeats Sandstone and Muav Limestone at Grand Canyon, thought to be about 520 Ma old, ranged from near 0 to about 900 Ma old.

. Note cartoon requires significant horizontal exaggeration just to show the peaks in the formation of crustal features, and the rock and fossil records. The simplest of these soft-bodied creatures were sponges. Other minerals were broken up into fine clay and silt muds that were carried far from shore but eventually settled on the sea floor and compacted to a rock we call shale. Moreover, Precambrian sedimentary rocks provide evidence they were deposited in the Flood. Such as the where Uranium 235 decays to Lead 207 with a half life of 710 million years. When living things die, they stop taking in carbon- 1.

What is Relative Dating?

why is relative dating of precambrian rocks difficult

Some three billion years ago, the Earth's atmosphere was virtually devoid of oxygen. Your goal is to study the smooth, parallel layers of rock to learn how the land built up over geologic time. Creationists reject the old ages of radiometric dating schemes. He thinks the Paleoproterozoic 2,500—1,600 Ma represents events of Day 4, and the Mesoproterozoic 1,600—1,000 Ma records those of Day 5. One example of an outlier is the 1. Suffice it to say that building forensic models on top of existing forensic uncertainties reduces our confidence in the final theory.

When I was a young child at school we had what was called a Natural History lesson. I firmly believe that all the ones we know have were formed during the Flood, but I'm not one to say there were no such things made by design during Creation Week. The methods are also intrinsically less accurate for long-ago rocks — ether the remaining U235 is a mere trace, or you have to use a different decay series with slower decay rates. All radiometric dating methods measure isotopes in some way. But the sun, moon, and other solar system bodies were not created until Day 4. And, the mud layer is older than the forest layer. However, recent experiments have shown that pollen fossils can survive the high temperatures and pressures required to form metamorphic rock.
