Geology
The geological structure of the Planý Vrch nature reservation is very simple. In the middle part of the protected territory there is a marked morphological ridge running roughly northeast-southwest, formed by serpentinite. Other occurrences of serpentinite are located at the northeast border of the reservation. An observant expert is sure to notice this greenish grey-black mineral that forms a number of significant and rare outcroppings. Among them are delicate antigorite infused with red pigment of magnetite with chromite, chlorite, rare spinel, rutile, and in places relicts of bronzite pressed with tromolite and antigorite. Serpentinite was mined in the northeast part of the protected area, as shown by the abandoned mines and mounds of waste material.
