The northern border of the massif is separated from the massif of the mountain Zeljina by the rivers Josanicka reka and Koznicka reka.
The eastern side is bounded by the rivers Rasina and Toplica valleys.
The region's geology dates back 70 million years ago when the older sedimentary rocks were exposed to the strong tectonic movements and to the volcano activity which caused dent and issue of the magmatic cliffs.
The later processes of erosion during past millenniums created present-day outlines of the relief of Kopaonik.
Climate of Kopaonik, with almost 200 sunny days annually, deserves credit for Kopaonik's other name - "mountain of the Sun". The southern position of the massif, level and openness of the terrain prevent continual detaining of cloudiness over the mountain. Colder and heavier air moves through the nearby valleys and ravines so that winter temperatures are not too low. Kopaonik has sub-alpine climate. Average annual temperature of the Flat Kopaonik is 3,7°C.
It starts snowing at the end of November and it snows until May, 159 days a year in average. On average, precipitation are higher than 1000 mm a year.
The volcano activity and discharge of hot mineral solutions caused changes on the nearby old rocks because of high temperatures and heavy pressures.That is how "mining region of Kopaonik" came to be, with a large number of mines from old times.
In the Kopaonik region, besides the usual ores: metals iron, lead and zinc, there are rare metals silver and gold and rare minerals: volastonite,fluor-spar, asbestos and others.
Besides thermal waters, there are also slightly mineralized waters on Kopaonik. In the first place, these are slightly radioactive springs Krcmar vode and Marine vode at the heights of 1700 -1950 m.
