Czwartorzędowe martwice wapienne koło Fordonu
Abstract
QUATERNARY CALCAREOUS TRAVERTINE NEAR FORDONThe area in which the calcareous travertine in question occurs is situated in northern Poland on the left bank of the Vistula river, north of Fordon (Fig. 1). The travertine is exposed at an altitude of 31.0-58.0 m. a.s.l., i.e. on the middle terraces and on the lower terrace of the river. In the upper terraces travertine has not been observed, and on the terraces above flood terraces it is found in a secondary deposits.The travertine is a fairly compact, locally friable, deposit; it occurs in fragments only in accumulated limestone masses. Generally the colour of this deposit is white or light-grey, sporadically (chiefly in the top) it is rust-coloured; in its interior part, travertine is black or dark-grey.Downloads
