Ivailovgrad gneiss

The gneiss is an often met and widely spread type of rock, belonging to the metamorphic rocks family with high degree of regional metamorphism. Usually the gneiss is composed of feldspar, granite, andalusite, quartz and mica. The colour of the rocks is determined by the minerals that it contains. Depending on their origin, the rocks are divided into orthogneiss (magmatic origin of the protolite) and paragneiss (sedimentary origin of the protolite).

Those have big size grains (up to a few millimeters grain size) with schistic texture and they are the basic rock in East Rodopi Mountains.

The gneiss extracted in Rodopi Mountains and in the Ivailovgrad region is found in two basic colors – silver-grey and golden-brown. It is characterized by the high resistance to changes in temperature and rough, non-slippery surface that makes it perfect for interior as well as exterior use.
