Which type of rocks are best for numerical dating using radiometric technique?
Igneous rocks
What is in the formation of igneous rocks but not in formation of metamorphic rocks?
igneous rocks form within earths surface
Do we have igneous rock in Nigeria?
No we do not have igneous rocks in Nigeria because there are no volcanoes in Nigeria and it is lava or magma that make igneous rocks.
How are minerals arranged in igneous rocks?
Most igneous rocks have a relatively homogenous mix of minerals which are interlocked.
How can you tell sedimentary rocks from others?
== == The age of a sedimentary rock formation can be estimated by comparing it to radiometrically dated rock formations that contain the same fossil organisms. Geologic time categories have been identified according to the radiometric dating of fossils and the fact that they appear only in certain time periods. Therefore, if you look at a rock formation and find a trilobite fossil that has been identified by previous dating techniques as Cambrian, you can be fairly certain that the formation you are looking at is also Cambrian.

Radiometric dating is least useful for dating what type of rocks?
Sedimentary Rocks
Scientists date igneous rocks to indirectly date nearby sedimentary rocks Why doesn't radiometric dating typically work on sedimentary rocks?
Sedimentary rocks contain bits of sediment, each much older than the rocks they form
What types of rocks are used in radiometric dating?
From a granite, a common mineral used for radiometric dating is the biotite mica component. For this mineral is among the last to form - as it forms at the lowest temperature compared to the other components of granite.This mineral contains potassium, 40K, which may be dated by the Potassium-Argon method. By radioactive decay, a small portion of the 40K decays to Argon. (The remainder of the potassium decays to a Calcium.)This Ar component is held in the mineral crystal, and by measuring the quantities of K and Ar, the age of the biotite is determined. [to an accuracy of about 1%.] For none of the Ar would be entrained in the previous molten state.All the K in your body is also susceptible to this decay!
What does radiometric dating tell geologist about some rocks and minerals?
their ages
Can use radiometric dating on all minerals to tell their absolute age?
No, radiometric dating can only be used on certain minerals that contain radioactive isotopes. These minerals include zircon, potassium feldspar, and biotite, among others. Not all minerals contain radioactive isotopes, so radiometric dating cannot be applied to all minerals.
How do you determine the age of igneous rocks?
Relative age can be determined using superposition and cross-cutting relationships. Absolute age can only be determined using radiometric dating methods, such as Rb-Sr.
What radiometric dating is best to date rocks younger than fifty thousand years?
Carbon Dating
