It provides an isotopic ratio. Simply taking a sample of igneous rock and dating it by itself will not give you the date that rock solidified on the surface. That would be a stupid thing to do and expect. Beneath the crust it is molten.

What you are dating is in part dependent on the ratios found in that liquid. Which is precisely the issue creationists have with dating rocks.
Why Are Igneous Rocks The Best Type Of Rock To Use For Radiometric Dating?
What they fail to mention is that this issue is one that scientists who use this method to date different strata are well aware of and have had to solve how to take into account. There are isotopic quantities in these rocks and once it solidifies these quantities are no longer subject to the potential change they were when they were liquid. So effectively each layer is analogous to a time measuring ruler with an unknown zero point and eqi-spaced markings from the point of solidification that have blurred labeling.
The way to resolve it is to get a point of absolute relevance and work from there. There are a number of methods to measure the age of something. You can measure the amount of time something has been exposed to sunlight. You can measure the isotopic content of an animal that has died.
You can measure how long it has been SINCE something was last exposed to sunlight, and you can work out how that reference point got to be where it is. Once you have this reference point you can take the current isotopic contents of the surrounding rock and work backwards, establishing the ratio that matches the age of the reference point. What has been achieved there now is a reference point for that rock. Now you set out to acquire more.
When you come to another layer, if it came from an earlier volcano the isotopic ratios will be different since it has been solid for longer.

You can then take what you've learned about the previous layer as well as seeking reference points in this layer and start to article source more about the new layer itself.
Over time you can begin to accumulate knowledge and understanding about the general ratios present in the molten rock below as well as a general timeline of when each layer came to the surface. It's time consuming work and takes a bit of working stuff out.
Like I said at the start, you can't really just pick up a lump of volcano rock. Take it to a lab and expect to immediately know when that rock came to the surface. There is another rock type that igneous rock converts into that can be used to determine precisely when the conversion between types took place. Off the top of my head I can't remember the name though and I've got to get to a meeting. A bit of searching online should be able to tell you which type.
Are basically the same shape as they were in the geological past. Recent geological events up toyears ago. What determines the type of fossil that has formed? What has been achieved there now is a reference point for that rock. Once you have this reference point you can take the current isotopic contents of the surrounding rock and work backwards, establishing the ratio that matches the age of the reference point.
There's 2 main types of rock that can be dated. Igneous and this other one which forms from igneous rock. So technically the answer that only igneous rock can be dated is correct but that answer is a simplification that is a little misleading.

I remembered what the name was. Metamorphic rock from igneous rock can be dated to give the time since the transition from igneous to metamorphic took place, so I've read. It provides information about when the igneous rock was formed. Get an MBA while working.
