Hot Rocks & the Problems They Cause

There are a number of definitions on what hot rocks are made up of but in general they are what we know as ordinary granite. Hot rocks are a remainder of a cosmic meltdown. In the molten planet, heavy minerals moved down to the bottom. Lighter elements, like those of granites, floated up to the top. To this day, they are still fixed in the earth’s crust as hot dry rocks. They are also one of the worse enemies a prospector can have. One important issue to remember about metal detectors though is that even the best and finest metal detector will respond to what is known as hot rocks. Hot rocks are much mineralized rocks that give some metal detectors a positive response. In gold prospecting hot rocks bring about problems, and why does this take place? Well, when the detector loop is passed over them they make a great deal of noise and in many occasions this misleads the prospector to thinking he has found a metal target. And they bring about inconveniences because they lead the prospector to think he may have found something when in fact he has only run into a hot rock. Although hot rocks might be a bit of a hassle for prospectors, it does not have to turn into such a big predicament for the reason that there is an approach to dealing with this problem. It is feasible to identify them. This will require of practice so that the prospector is able to make out when it is a hot rock or a real metal target. Take into account also that a rock can be a hot rock in one area while it may not be in another area. As a result this means that a hot rock is a “hot rock” depending on the type of ground that it is situated in, and depending on the amount of mineralization, the “hotter” the rock will be.

If a rock causes there to be a sound in the detector, it is caused by the change in mineralization in the earth. As a matter a fact, there are some rocks that are so mineralized that they not only make a signal that sounds like metal but they can also cause the audio of the detector to overload and on occasion neutralize the effectiveness of the loop. This means that they can literally destroy the use of the detector so that it will not detect any target.
