What two methods of radiometric dating are used for rocks more than 10 million years old?
what are two radio active isotopes that are usful for dating rocks that are older than ten million years
What else can I help you with?
Is it true that all rocks can be dated radiometrically?
Not all rocks can be accurately dated using radiometric methods. This is because some rocks may not contain the necessary minerals or isotopes required for radiometric dating. Additionally, radiometric dating may not be suitable for extremely old rocks due to limitations of the dating techniques.
Would you use uranium- lead radiometric dating to find an igneous rocks age?
would you use uranium-lead radiometric dating to finnd an igneous rocks age
What would you use to do absolute dating of a rock layer?
To do absolute dating of a rock layer, you would typically use radiometric dating methods such as radiocarbon dating, uranium-lead dating, or potassium-argon dating. These methods rely on the decay of radioactive isotopes in the rocks to determine the age of the rock layer.
Sedimentary rocks can't be dated?
Sedimentary rocks cannot be given an absolute date by radiometric testing, but they can be given an estimated date from a few geological laws, for example if a bed of desert sandstone ins under a bed of limestone there is a law that says that the sandstone is older.
When radiometric dating is applied to metamorphic rocks what is the date obtained?
Time since metamorphism.
How do scientist determine the ages of rocks?
They can use either radiometric dating or magnetostratigraphy.
Radiometric dating does not usually work with sedimentary rocks because they?
Radiometric dating is not usually effective for sedimentary rocks because they are formed from fragments of other rocks and do not contain the necessary minerals for radioactive decay dating to occur. Sedimentary rocks are composed of material that has been transported and deposited, which can result in a mixture of ages making it difficult to determine the exact age using radiometric dating methods.
Scientists date igneous rocks to indirectly date nearby sedimentary rocks Why doesn't radiometric dating typically work on sedimentary rocks?
Radiometric dating relies on the presence of radioactive isotopes that decay over time into stable isotopes. Sedimentary rocks are composed of weathered fragments of other rocks and minerals, so they do not usually contain the necessary radioactive isotopes for radiometric dating. This makes it difficult to directly date sedimentary rocks using radiometric methods.
What are two methods geologist use to determine the age of a rock?
Geologists use relative dating methods to determine the sequence of events that led to the formation of rocks by analyzing the layering of rocks. They also use absolute dating methods such as radiometric dating to determine the numerical age of rocks by measuring the decay of radioactive isotopes within them.
Radiometric dating is least useful for dating what type of rocks?
Radiometric dating is least useful for dating sedimentary rocks because they are formed from the accumulation of sediments, making it difficult to determine the original isotopic composition.
What are four types of radiometric dating?
Four types of radiometric dating are potassium-argon dating, uranium-lead dating, carbon-14 dating, and rubidium-strontium dating. These methods are commonly used to determine the age of rocks and fossils based on the decay of radioactive isotopes.
Is it true that all rocks can be dated radiometrically?
Not all rocks can be accurately dated using radiometric methods. This is because some rocks may not contain the necessary minerals or isotopes required for radiometric dating. Additionally, radiometric dating may not be suitable for extremely old rocks due to limitations of the dating techniques.
What are the 3 types of radiometric dating and what are the years that they are good for?
The three types of radiometric dating are potassium-argon dating (good for dating volcanic rocks up to billions of years old), uranium-lead dating (good for dating rocks older than 1 million years), and carbon-14 dating (good for dating organic materials up to about 50,000 years old).
Most sedimentary rocks are readily dated by radiometric methods True False?
False. Most sedimentary rocks cannot be directly dated by radiometric methods because they are composed of sediments that were already eroded and transported from existing rocks. Instead, geologists use relative dating techniques to determine the sequence of events in which sedimentary rocks were formed.
Would you use uranium- lead radiometric dating to find an igneous rocks age?

How old are the Luna maria?
Radiometric dating of moon rocks from the maria indicate that they formed about 3.16 to 4.2 thousand million years ago.
Which type of rocks are best for numerical dating using radiometric technique?
Igneous rocks
