Igneous rocks
igneous rocks form within earths surface
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.
Most igneous rocks have a relatively homogenous mix of minerals which are interlocked.
== == 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.

Igneous rocks
Radiometric dating is less useful for dating sedimentary rocks because they are made up of material that has been transported and deposited from other sources, making the age of the sedimentary rock different from the age of the material within it. Igneous rocks directly crystallize from magma and accurately retain the age of their formation through radiometric dating.

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.
Radiometric dating is measured by analyzing the decay of radioactive isotopes in rocks and minerals. Scientists measure the ratio of parent isotopes to daughter isotopes to determine the age of a sample. By calculating the rate at which the parent isotope decays into the daughter isotope, the age of the sample can be estimated.
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.
Igneous rocks do not have a specific age. They are formed from lava or magma cooling and solidifying, which can happen at any point in time. The age of an igneous rock can be determined through radiometric dating techniques.
Radiometric dating works to determine the age of rocks and fossils by measuring the decay of radioactive isotopes within them. This decay occurs at a constant rate, allowing scientists to calculate the age of the sample based on the amount of remaining radioactive isotopes.
Radiometric dating measures the decay of radioactive isotopes in rocks and fossils to determine their age. By comparing the ratio of parent isotopes to daughter isotopes, scientists can calculate the age of the sample based on the known rate of decay for that particular isotope.
