Its mineralogical constitution is not simple; in some parts the rock is of a cherty
, in others of a felspathic nature, including thin veins of serpentine.
The studied succession consists of 7 lithofacies expanded from Barnolas and Simo (1987) including: boulder-pebble conglomerates, graded pebble conglomerates, graded peloidal-ooid packstones, graded oolites, calcilutites, Posidonia coquina and cherty
In the study area lithological units is outcrops the second to fourth periods, which from old to new are as follows: phyllite, ouartzite, paragneiss, marble, shell, sandstone with tufa, volcanic rocks, crystalline limestone locally with fosolina, metamorphic volcanic and tufa, cherty
limestone, phyllite, metamorphic quartzarenite, micaschist, metadolomite, amphibolite, limestone, shale and sandstone, schist hornfels, orthogneiss, granodiorite, oput rock, shale and phyllite sandstone, granite, granodiorite, diorite, dolomitic lime, radiolarit breccia, rodist lime, orbitoline, radiolarat, black and blue marl with limestone, alluvium.
Pokotylo (1994) provides a description of the primary geological deposits at Vihtr'ii Tshik, identifying three grades of material in the immediate vicinity of the site, including 1) light grey shaley material, 2) material containing some banding with a fine-grained black cherty
matrix, and 3) material exclusively composed of a lustrous black cherty
