Methods of Geological Dating: Numerical and Relative Dating

Primary source references As a preface to this document, I want to point out that it is a shame that we have to continue to refute the same arguments that evolutionists keep bringing up over and over again in their attempts to argue against the fact of creation, which fact has been well established since the day the earth was created ex nihilo several thousand years ago. It is also a shame that the masses have bought all this based on some circular reasoning about fossils, where fossils tend to be found buried, similarities between various life forms, the presence of certain decay products in rocks, and other inherently speculative arguments about the past, based on phenomena that exist in the present. If I hope to accomplish anything, it will be to simply encourage critical thinking. One must get past the arguments ad populum that its popularity counts for something , ad hominem that if you attack the person making the argument, this counts for something , and especially ad baculum that there are people who have the clout to decree it as true , to ask the key questions and challenge the unsubstantiated assumptions and thinking of those who would hold to the evolution position. Today there are an increasing number of anti-creationist authors who are producing books and periodicals that make this relatively brief presentation insufficient to deal with all the points in dispute. Those defending creation today who don’t have the time to devote their life’s study to gaining expertise in all fields of inquiry must principally be prepared to think critically, logically, and challenge unsubstantiated assumptions made by these people. They must also keep a level head in the face of some vicious attacks and diatribes that will be directed against them, as is advised in the scriptures 1 Peter 3: By way of definitions, I want to point out that when I speak of “evolution,” I am referring to the popular contemporary use of the word, which in a nutshell is the belief that all life forms are related by ancestry, and that the first life form occurred spontaneously, all due to completely natural processes. When I speak of “creation,” I am referring to the inherently obvious fact that the origin of all life forms can be attributed to a creator who purposefully created them with planning and intent, and the documented fact that this occurred over the course of a week’s time several thousand years ago.

It was prominent enough in lower-class London speech to attract the attention of Charles Dickens, who used it in in an early sketch, but little else is certain. Claims were once made that it was Yiddish, despite the absence of a plausible Yiddish source. But evidence for any metaphorical use of this phrase in Irish is lacking, and kibosh is not recorded as spoken in Ireland until decades after Dickens’ use.

Buffalo blasts Arizona, sends a warning,” 16 Mar. Justice for All,” 17 Jan. A number of etymologies are summarized by Anatoly Liberman in online postings to the OUPblog maintained by Oxford University Press “Unable to put the kibosh on a hard word,” May 19, ; “Monthly gleanings,” July 28, ; “Three recent theories of ‘kibosh’,” August 14, ; “Etymology gleanings,” November 29, The recent theories to which he alludes see the following as sources for kibosh: The latter hypothesis is argued at length in a monograph by Gerald Cohen, Stephen Goranson and Matthew Little, Origin of Kibosh Routledge, , which also summarizes recently found antedatings to citations of the word in the Oxford English Dictionary dating the word with certainty to , and perhaps to Liberman may well be correct that “with the present evidence at our disposal, the chance of unearthing the origin of kibosh is vanishingly small.

Eat one of those and your tummy will curl right up! Seriously speaking, a favorite attack on radiometric dating involves dangling “horror stories” about gross errors before the reader, thus giving the impression that radiometric dating is totally unreliable. Woodmorappe , with his collection of some bad radiometric dates, must surely be the master of that technique. Upon being presented with claims that radiometric dating is totally erroneous, a question naturally arises: If radiometric geochronology is half as bad as Woodmorappe’s list suggests, then how in the world did geologists ever arrive at a tight consensus for the official dates?

Look at the various radiometric tables in use over the last 20 years or so and you will find, at least for the fossil-bearing strata, a remarkably tight agreement.

Exxon group modified this definition to “a surface separating younger from older strata , along which there is evidence of subaerial erosional truncation and, in some areas, correlative submarine erosion or subaerial exposure, with a significant hiatus indicated” or downdip correlative conformities marking a hiatus in sedimentation Vail, et al.

Catuneanu and Hunt and Tucker suggest the correlative conformity forms on the paleo-sea floor at the end of forced regression and correlates with the seaward termination of the subaerial unconformity.

Radiocarbon dating (also referred to as carbon dating or carbon dating) is a method for determining the age of an object containing organic material by using the properties of radiocarbon, a radioactive isotope of carbon.. The method was developed in the late s by Willard Libby, who received the Nobel Prize in Chemistry for his work in It is based on the fact that radiocarbon (

These formations may have resulted from carcass burial in an anoxic environment with minimal bacteria, thus slowing decomposition. Stromatolites Lower Proterozoic stromatolites from Bolivia , South America Stromatolites are layered accretionary structures formed in shallow water by the trapping, binding and cementation of sedimentary grains by biofilms of microorganisms , especially cyanobacteria.

While older, Archean fossil remains are presumed to be colonies of cyanobacteria , younger that is, Proterozoic fossils may be primordial forms of the eukaryote chlorophytes that is, green algae. One genus of stromatolite very common in the geologic record is Collenia. The earliest stromatolite of confirmed microbial origin dates to 2. The most widely supported explanation is that stromatolite builders fell victims to grazing creatures the Cambrian substrate revolution , implying that sufficiently complex organisms were common over 1 billion years ago.

Factors such as the chemistry of the environment may have been responsible for changes. Cyanobacteria as well as extremophile Gammaproteobacteria are thought to be largely responsible for increasing the amount of oxygen in the primeval earth’s atmosphere through their continuing photosynthesis. Cyanobacteria use water , carbon dioxide and sunlight to create their food. A layer of mucus often forms over mats of cyanobacterial cells.

In modern microbial mats, debris from the surrounding habitat can become trapped within the mucus, which can be cemented by the calcium carbonate to grow thin laminations of limestone. These laminations can accrete over time, resulting in the banded pattern common to stromatolites.

Organism The characteristics of life Since there is no unequivocal definition of life, most current definitions in biology are descriptive. Life is considered a characteristic of something that preserves, furthers or reinforces its existence in the given environment. This characteristic exhibits all or most of the following traits: Living things require energy to maintain internal organization homeostasis and to produce the other phenomena associated with life.

A fossil (from Classical Latin fossilis; literally, “obtained by digging”) is any preserved remains, impression, or trace of any once-living thing from a past geological es include bones, shells, exoskeletons, stone imprints of animals or microbes, objects preserved in amber, hair, petrified wood, oil, coal, and DNA remnants. The totality of fossils is known as the fossil record.

The way it really is: Even the way dates are reported e. However, although we can measure many things about a rock, we cannot directly measure its age. For example, we can measure its mass, its volume, its colour, the minerals in it, their size and the way they are arranged. We can crush the rock and measure its chemical composition and the radioactive elements it contains. But we do not have an instrument that directly measures age. Before we can calculate the age of a rock from its measured chemical composition, we must assume what radioactive elements were in the rock when it formed.

It may be surprising to learn that evolutionary geologists themselves will not accept a radiometric date unless they think it is correct—i. It is one thing to calculate a date. It is another thing to understand what it means. Field relationships A geologist works out the relative age of a rock by carefully studying where the rock is found in the field.

See Article History Dating, in geology , determining a chronology or calendar of events in the history of Earth , using to a large degree the evidence of organic evolution in the sedimentary rocks accumulated through geologic time in marine and continental environments. To date past events, processes, formations, and fossil organisms, geologists employ a variety of techniques. These include some that establish a relative chronology in which occurrences can be placed in the correct sequence relative to one another or to some known succession of events.

Radiometric dating and certain other approaches are used to provide absolute chronologies in terms of years before the present. The two approaches are often complementary, as when a sequence of occurrences in one context can be correlated with an absolute chronlogy elsewhere. Ankyman General considerations Distinctions between relative-age and absolute-age measurements Local relationships on a single outcrop or archaeological site can often be interpreted to deduce the sequence in which the materials were assembled.

This then can be used to deduce the sequence of events and processes that took place or the history of that brief period of time as recorded in the rocks or soil. For example, the presence of recycled bricks at an archaeological site indicates the sequence in which the structures were built. Similarly, in geology, if distinctive granitic pebbles can be found in the sediment beside a similar granitic body, it can be inferred that the granite, after cooling, had been uplifted and eroded and therefore was not injected into the adjacent rock sequence.

Literature: Literature, a body of written works. The name has traditionally been applied to those imaginative works of poetry and prose distinguished by the intentions of their authors and the perceived aesthetic excellence of their execution. It may be classified according to a variety of systems, including language and genre.

But not everything expressed in words—even when organized and written down—is counted as literature. Those writings that are primarily informative—technical, scholarly, journalistic—would be excluded from the rank of literature by most, though not all, critics. Certain forms of writing, however, are universally regarded as belonging to literature as an art.

Individual attempts within these forms are said to succeed if they possess something called artistic merit and to fail if they do not. The nature of artistic merit is less easy to define than to recognize. The writer need not even pursue it to attain it. On the contrary, a scientific exposition might be of great literary value and a pedestrian poem of none at all. The purest or, at least, the most intense literary form is the lyric poem, and after it comes elegiac, epic, dramatic, narrative, and expository verse.
