Carbon-14 dating is normally used by archaeologists rather than geologists because it ceases to be accurate at ages over 50,000-60,000 years. The half life of carbon 14 is about 5,000 years, so it becomes increasingly difficult to detect at time much longer than this.
Geologists use radiometric dating employing other elements that decay more slowly such as uranium/lead and potassium/argon for rocks, particularly very old rocks.

∙ 13y ago(1) After several times the half-life, the amount of C-14 that remains is so small that it is hard to measure accurately. (2) It is only useful when you can assume that a certain number of years ago, an object got most of its carbon from the atmosphere. This basically restricts it to dating living beings.

What do scientists use to determine a fossil's relative age?
Carbon14 dating (isotopic dating)
An artifact is found that some are claiming is 30000 years old 3.1 percent of the original carbon14 is present The halflife of carbon14 is 5730 year?
Yes, but the dating is only off a little (500 years or so).
What happens to the amount of nitrogen14 as the carbon14 decays?
Remains the same
How many protons neutrons and electrons are in carbon14?
7 protons, 7 neutrons and 7 electrons
Does the carbon14 have more protons neutrons or electrons than carbon12?
It has the same number of protons and electrons, but two more neutrons.
What Limitations are there of using carbon14 to date rocks?
The main limitations of using Carbon14 dating to find the age of something that is carbon base are firstly the possibility that carbon may be absorbed by some things making it more difficult to get an absolutely accurate age and secondly, with Carbon14 only having a half life of 5,568 years the maximum theoretical limit for detection is 100,000 years.

Why is carbon14 dating not accurate for estimating the age of materials more than 50.000 years old?
Too little carbon-14 remains after 50,000 years
A researcher who uses carbon dating on anciet items?
The half life of C14 is about 5700 years, so items that are a few multiples of this time are suitable for carbon14 dating. Most archaeological items are suitable, and some young fossils.
What are the limitations of dating?
It is all on the person and what they like or want.
What are the limitations of using uranium-238 in dating the age of objects?
The limitations are that it only dates the ages of rocks.
What happens to the amount of nitrogen14 as the carbon14 decays?
Remains the same
Is it good to do any webcam dating online?
There are many benefits to webcam dating, as well as limitations. Webcam dating is easier, and you still get to talk and have fun. But you do not get the exercise, or have as many options for entertainment for the date.
What is a limitation of dating?
There's no specific limitations- it's just what you and your partner are comfortable doing with eachother.
What two things must scientist measure to find the absolute age of a rock?
scientists use carbon14 and potassium argon to find absolute age of rock
What is the mass number of carbon14?
Carbon is a non metallic element. Mass number of it is 12.
