How can the geologist determine the age of the fossil if the geologist finds a fossil in a layer of sedimentary rock that lies in between 2 igneous extrusions?
The geologist will most likely take samples of the two lavas forming the igneous intrusions and use radiometric dating techniques to find their ages. He then would know that the age of the sedimentary rock was somewhere between the two. He may also look for (index) fossils within the sedimentary rock which may also give him an indication of the age of the sediment.
What do you use Igneous rocks for?
igneous rocks are used for blilding and for long lasting moument.
Suppose a lava flow was found between two sedimentary rock layers How could you use the lava flow to learn about the ages of the sedimentary rock layers?
Because of geologic events such as plate tectonics and volcanism, suitable material for radiometric dating, such as volcanic tuff, solidified lava, and igneous intrusions have been found as layers on, in, and cut through layers of sedimentary rock.Intrusions are always younger than the rock body they penetrate, meaning that the sedimentary rock in which intrusions are found will be older than a radiometrically dated sample of the intrusion. Lava flows and volcanic ash which form layers in rock will be younger than the rock below and older than the rock above. The solidified intrusions and lava flows can be dated with radiometric techniques.The radiometric dating of suitable rocks (i.e. igneous or metamorphic) in proximity to their sedimentary counterparts, therefore allows the sedimentary rock to be dated as well.
Why can't geologist use the carbon-14 method to date igneous rocks?
Igneous rocks do not contain much carbon.
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 evidence would a scientists use to determine the absolute age of a fossil found in sedimentary rock?
The Igneous intrusions and extrusions near sedimentary layers.
What evidence would a scientist use to determine the absolute age of a fossil found in a sedimentary rock?
Uranium is the element that decays at a rate that relates to the sample. Uranium is the element that decays at a rate that relates to the sample.

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.
