Description of primary interest:
In the gravel pit in Witów, Witów Series and Quaternary deposits are visible. Witów Series (ca. 22 m) consists of thick beds of sand (crumbling sandstones) with gravel, gravels and cobbles, sometimes very coarse-grained, and sometimes with the boulders admixture. Maximum diameters of clasts reaches up to 0.7 m. Clasts are formed mainly from the most resistant sandstones of Carpathian origin. They are accompanied by crystalline rocks and limestones of the similar origin. Witów Series was formed by braided river. In the intercalations of siltstones and in sandstones fossil plant remains (Late Miocene to Pliocene age) are found. Also joints and faults are present. Lower part of Quaternary sediments consists of mixed gravels, material from Witów Series and that of glacial origin - mainly Scandinavian crystalline rocks and flints (San II glaciation). In the top of the outcrop loesses Vistulian age occur.
