Are limestone and dolomite considered monomineral rocks?
regular rotors don't get rid of the heat fast enough drilled ones do,the difference is also in the stopping power on those,you can tell a difference in the way a car will stop with drilled rotors on it,and drilled rotors can be turned it just takes a lot longer to turn them and most shops wont attempt to turn the because it breaks the cutters off their brake machine,good luck.
The main reason for using slotted or drilled rotors is to displace heat, they really don't have any braking advantage over plain rotors, (that I know of) They would be hard on stock break pads, so you would probably need high capacity brake pads as well, they will make you stop faster, I don't think that drilled rotors can be turned, not sure about slotted. hope that helps
This Site Might Help You. RE: Brake rotors? Whats the difference between Plain, Drilled, Slotted, vented brake rotors? What are the best?
Because the rocks only contain one mineral. Limestone usually contains only one mineral (calcite grains) while dolostone (also called dolomite) only consists of the mineral dolomite. In contrast, the mineral grains in gabbro for example would be mainly pyroxene and plagioclase and does therefore not consist of just one mineral and is not considered a monomineral rock. Hope this helps.
