A rock drill can be useful in determining the composition of a rock’s underlying mineralogy.
It is also useful for identifying minerals in rock fragments, and even rocks with a low or unknown mineralogy (such as rocks with only trace elements of other elements).
In fact, it is the very definition of a geology textbook.
This is because rock drill is the only geology tool that has the ability to determine the composition or isotopic composition of minerals.
So if you have a drill, you have the ability (along with a number of other useful instruments) to identify minerals in rocks that you do not have access to otherwise.
For instance, you could use a rock drill to look for the isotopic signature of a rare element (called a isotope signature) of a mineral, which you would not normally be able to do using your standard chemistry lab.
And you could do this with any mineral, including those that are already known to have a very low or uncertain mineralogy!
Rock drill is a geologic tool, but not just a tool for geologists and mineralists, because rock drilling has also been used by geophysicists and paleontologists.
For example, geochemists have used rock drill for dating rocks, for measuring the age of rock fossils, and for studying the isotope composition of rocks.
However, many of these applications of rock drill are not useful for geology.
Most importantly, the use of rock drilling to determine mineralogy requires that you have some knowledge of the rocks underlying the minerals.
This can be done by using the techniques of mineralogy theory.
For those of you who do not know this theory, mineralogy is the study of minerals and their chemical structure.
This allows us to make measurements of their chemical composition using the elements in their composition.
For most rocks, the composition is determined by using standard methods.
For the minerals we are interested in, however, we are usually looking at the elements within the minerals that are known to be present within the rocks.
We also use a variety of other methods, such as isotope and molecular dating, in order to determine whether the minerals are mineralogical (or isotopic) minerals or rocks.
A rock mineral has a specific composition, called a mineralogy, that it has in its rocks.
This determines the way in which it behaves when heated and cooled, and also the composition in the rocks around it.
The isotopic ratio of a particular mineral is a measure of how much of that mineral is contained in that specific mineral.
For rock drill this can be calculated by using an isotope (a unit of measurement) or molecular (a measure of the amount of a specific element in a specific mineral) ratio.
These two terms are the same thing, so you can think of them as two different terms for measuring a specific chemical element.
