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 else can I help you with?
Are only sedimentary rocks used for relative age determination?
No, sedimentary rocks are commonly used for relative age determination due to their layering and formation process. However, other types of rocks like volcanic rocks and metamorphic rocks can also be used to determine relative age based on principles of superposition, cross-cutting relationships, and faunal succession.
How can you determine if a igneous rock has had an intrusive or extrusive origin?
== Grain size. Most intrusive igneous rocks will have visible crystals. Crystals in most extrusive igneous rocks are not easily visible.
How old are igneous rocks?
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.
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
When molten rocks cools what rocks form?
igneous rocks
What do paleontologists do to determine the actual age of rocks?
Paleontologists use carbon dating to determine the age of rocks.
What can determine the size of grains in igneous rocks?
Cooling rate of molten rock
What will determine if a rock becomes an igneous or metamorphic rock?
Geological processes form rocks. Igneous rocks are made from magmas. Metamorphic rocks are made by changing the physical environment of a previously existing rock.
Why can't scientist use carbon to determine the age of an igneous rock?
Largely because igneous rock doesn't contain any carbon; any carbon would be vaporised in the heat of molten rock. Uranium is more commonly used to date igneous rocks.
What are igneous rocks that form over the surface?
Rhyolititcen rocks.
What do you call rocks that have been formed from the hot molten material within the earth's crust that has cooled and hardened?
Igneous rocks are formed by the solidification of molten materials.
Are igneous rocks made up of igneous rocks?
Sedimentary rock can be made up partially of igneous clasts, but igneous rock is igneous rock.
