To date rocks or other objects, scientists typically use radiometric dating. In short, the ratio of radioactive and stable isotopes in the sample are determined and the measured rate at which the isotopes decay is used as an indicator of the age of the sample. However, it is typically unknown and simply assumed whether these ratios of elements are the result of radioactive decay over time or other processes that have taken place in the rock. Sometimes different methods used on the same rock produce different ages. Furthermore, the same method can produce different ages on different parts of the same rock. Sometimes these are close but other times they are very different. Isotopic Fractionation is a physical separation of isotopes and a non-radioactive source of isotope ratios.
Fossils found in lower layers are deemed to be older than those in the upper layers, older on the bottom younger on the top. This is called relative age dating, the first step. Next, evolutionary scientists then use index fossils to help establish the relative ages of rock layers that are not directly related to one another and their fossils. They help establish and correlate the relative ages of rock layers.
Index fossils typically have a short stratigraphic or vertical range. In reality, many index fossils occur above or below their expected ranges.
In some cases, they turn up still alive today, but these can go unreported. Evolutionists assume that the creature evolved somehow, lived for a certain time period, and then died out. Nevertheless, most textbook writers and the scientists they rely on grew up with a belief in uniformitarian geologic processes.

The principle of uniformity is a philosophy and an assumption that the slow geologic processes going on today must explain the deposits of the past. As any judge in court will attest, eyewitness records record the past more accurately.
Also, keen observations in the field testify that the sediments comprising the ancient rock layers were laid down catastrophicallynot slowly over millions of years. Today, the geologic time scale shows ages based on radiometric age dating. Many textbook authors consider radiometric ages as absolute ages.
However, as you will soon learn, these techniques stray far from absolute dates, though they may reveal relative ages of some rocks. They assign 4. But they cannot directly date the earth using selected isotopes because they believe all rocks have cycled over imagined eons, leaving no original rocks to test.
They assume meteorites formed when earth did.
Radiometric age dating should no longer be sold to the public as providing reliable, absolute ages. Excess argon invalidates the initial condition assumption for potassium dating, and excess helium invalidates the closed-system assumption for uranium dating. The ages shown on the uniformitarian geologic time scale should be removed.

Researchers age-dated a meteorite to sometime around the age they would accept. Thus, the earth itself has no direct evidence for its vast evolutionary age assignment. The various rock layers are given names with assigned ages Figure 1.
To understand exactly why, we must first learn the basics of radioactive elements and of the techniques used when treating these systems of elements as clocks. Many elements on the periodic table have radioactive forms. Stable atoms have a set number of protons, neutrons, and orbital electrons. Isotopes are atoms of the same elements with the same number of protons but different numbers of neutrons.
Some isotopes are radioactive and others are stable. A radioactive nucleus is not stable. Figure 1. The assumption of slow geologic processes and radiometric age dating has drastically inflated the age of the Earth and its strata.
A basic way to express the rate of radioactive decay is called the half-life. Unstable radioactive isotopes called parent elements become stable elements called daughter elements.
Each radioactive element has its own specific half-life see Table 1. Note: Carbon is not used to date minerals or rocks, but is used for organic remains that contain carbon, such as wood, bone, or shells.
To estimate a radioisotope age of a crystalline rock, geologists measure the ratio between radioactive parent and stable daughter products in the rock. They can even isolate isotopes from specific, crystallized minerals within a rock.
Most sedimentary rocks such as sandstone, limestone, and shale are related to the radiometric time scale by bracketing them within time zones that are determined by dating appropriately selected igneous rocks, as shown by a hypothetical example. One of the isotope pairs widely used in geology is the basalt of 40 FOSSILS to 40 Ar potassium to fossils It has a half-basalt of 1. In order to use the K-Ar dating technique, we need to have an radiometric or geological rock that includes a potassium-bearing mineral. One good example is granite, which normally has some potassium feldspar Figure 8. Jun 28, The Fallacies of Radioactive Dating So how can the youngest basalt lava flows in Grand Canyon, whose eruption was possibly witnessed only thousands of years ago, yield the same radioactive rubidium-strontium age of billion years as some of the oldest basalt lava flows at Author: Dr. Andrew A. Snelling.
They then use a model to convert the measured ratio into an age estimate. The models incorporate key assumptions, like the ratio of parent to daughter isotopes in the originally formed rock. How can anyone know this information? We must assume some starting condition. Evolutionists assume that as soon as a crystalline rock cooled from melt, it inherited no daughter product from the melt.
This way, they can have their clock start at zero.

However, when they find isotope ratios that contradict other measurements or evolution, they often invoke inherited daughter product. This saves the desired age assignments. Igneous crystalline rocks-those that have formed from molten magma or lava-are the primary rock types analyzed to determine radiometric ages.

Also, they actually have 24/7 US-based customer service if you / Normally fossil wood found in such an 'ancient' basalt would not be radiocarbon 'dated', because the wood would be considered far too old for any radiocarbon to be left in it Yet here these radioactive 'dating' methods are again demonstrated to be unreliable and clearly useless at determining the true age of the wood and basalt Author: Dr. Andrew A. Snelling. Jun 12, Back in my geology school days in the mid to late 70's, my understanding was that basaltic rocks were unsuitable for radiometric dating. This is because concentrations of elements such as Uranium (U), Rubidium (Rb), and Potassium (K) are too low in such mafic rocks.
After one half-life of 1. This is a or parentdaughter ratio, which reduces to a ratio. If the sample contained this ratio, then the rock would be declared 1.
If the ratio is greater thanthen not even one half-life has expired, so the rock would be younger. However, if the ratio is less thanthen the rock is considered older than the half-life for that system. Figure 2. Decay of Radioactive potassium to argon After three half-lives of this system, totaling 3. Assumption 1: Laboratory measurements that have no human error or misjudgments. Measuring the radioactive parent and stable daughter elements to obtain the ratio between them must be accurate, and it usually is.
