How do geologists determine the age of various fossils?

How do geologists determine the age of various fossils? Topic: Strata research
May 22, 2019 / By Delight
Question: Radiocarbon dating is used for organic remains? not impressions in rocks surely??? All of the radioactive dating methods are unreliable in determining the age of the earth, fossils, and the strata in which fossils are found. Radiocarbon, potassium-argon, and the even less-proven uranium and radio-calcium methods depend too much on nonfluctuating radioactive conditions through time. (It has already been noted that radioactive conditions have fluctuated through time.) Additionally, some scientists have suggested that a world-wide flood would cause rapid decay in radioactive elements causing those elements to appear older than their actual age.

they use many methods but the two they use the most would be something called carbon dating. and the other is judging by a chart drawn from the layers of the earth. but heres the deal both of these are unreliable. carbon dating has screwed up on the age of alot of fossils. once somebody put a LIVING mulisc through the carbon dating process and said that it was really old. i dont remember the exact age they said but it was no less than 1,000. and judging by the layers of the earth is inaccurate. if you ask a scientist to show you were the layers of the earth line up with the chart they will not be able to show you. im not an expert on these things but i have researched many of the theories on creation and evolution. But the most helpful thing i found that explained creation and evolution was a cd called "top ten proofs of a young earth" by Bob Dutko. if you want to understand these things i recommend you listen to it. :)

Bryanne Originally Answered: How do petroleum geologists use higher level math?
If you are analyzing flow beneath the surface, you will need to apply Darcy's Law using the groundwater flow equation which is calculus based. Computer models use linear approximations to solve these types of values. I doubt you would ever use calculus as a well logger though. To answer your question about most of these equations derived using calculus, they're all derived using calculus.

I have forgotten just about all of my advanced calculus. I don't use those equations in everyday situations. Computers do the computations. Maybe there are some geos that do but I don't.

See my answer to your related question. Once rocks are dated (either relatively or absolutely), the fossils in them can be dated (either relatively or absolutely). You are correct that radiocarbon cannot usually be used to date fossils because the fossils are either older than the limit of this particular technique or they do not contain any organic matter in them any more (having been replaced by minerals). Below is a link to a US Geological Survey publication that details relative and absolute dating, as well as the use of index fossils. EDIT: Your comment on the "unreliability" of radiometric dating is simply incorrect. The processes that dictate decay are NUCLEAR ones - they occur in the nucleus of an atom. The electron cloud shields an atom form most effects of temperature and pressure (outside those seen in a star). Conditions on earth are simply not extreme enough to influence nuclear processes. Check out the article below "Radiometric Dating from a Christian Perspective" to get a good overview of the whole topic as well as answers to young-earth creationist objections. Enjoy!

According to Ian Juby, founder of the International Creation Science Special Interest Group for Mensa members, http://www.icssig.org and a sustaining member of the Creation Research Society: http://creationresearch.org Even the evolutionists have acknowledged that fossilization must happen rapidly - and can happen in hours. They also acknowledge that to make a fossil, the organism has to be buried rapidly. Now they would claim a local flood or sandstorm, but when you look at these fossil beds, they literally cover large portions of entire continents, and can be found on multiple continents - evidence that it certainly was no "local flood."

Most animals don't get fossilized. They die, and their bodies are destroyed or eaten. Only rarely they are fossilized. Most fossils are of marine creatures. They live in the sea (or lakes). They fall to the bottom when they died. Then their get buried in sediments or landslides or mudslides at the bottom. Eventually those sediments/mud turn to rock. The geological column happens because this happens again and again, over millions and millions of years. Even if it only happens once in a ten thousand years, wait long enough and it happens again. Of course there can be long periods where no new fossils or even no new sediments are being laid down in a particular area - hence gaps. My your additional comments, about rotting - I guess your real question is why doesn't the body rot to nothing.rather than fossilizing The answer to this, is that most times it does, completely, leaving no fossil. Sometimes however, just by chance, the body gets buried in air-tight mud or sand (for example, because of falling sediments or a landslide or a major flood,) or ash (say from a nearby volcano) sooner or later, so in these kind of situations - the body doesn't rot completely. This kind of event is a lot more likely for animals living in the sea than for land animals. For a land animal, the animal needs to fall into a river or swamp (and not got smashed to pieces), or die on a flood plain (imagine living next to the Mississippi when it bursts it banks) - and then get buried. That's why most fossils are from marine animals. Also, sometimes parts of the body rots For vertebrates, the most likely parts of the body not to rot, are the teeth, since they are hard. Hence many vertebrate fossils are just teeth. After teeth, other hard body parts are next most likely to survive - bones, horns, etc. And only very rarely we get an impression of soft body tissues such as internal organ, skin, feathers, etc. The reason you get layers and layers of these rocks, is things happen again and again for millions of years. If you stood on the flood plain by a major river, and it had a flood every 100 years, wait 1 million years, and you've had 10,000 floods
