Geology
Short characteristics of the site: Brno Massif, diorite zone. Road cut exposing ultramafic and ultrabasic rocks. Serpentinized ultrabasic rocks with chlorite aggregates with traces of banding. Diorite with xenoliths of surrounding rocks penetrated into ultramafic rocks. Serpentinites, except of serpentine, locally contain clinopyroxene, tremolite, carbonates, talk and phloogopite. Relics of olivine can be found. All rocks are affected by minor faults.
