Abstract

MINERALIZATION OF THE JULRASSIC LIMESTONES OF THE INOWROCŁAW REGION (CENTRAL POLAND)The occurrence of iron sulphides in the Malm sediments of the Kujawy region is a matter of common knowledge. Hereby we may distinguish two kinds of this occurrence: either in the shape of concretions of sometimes remarkable size (up to 70 cm.) or in the shape of distinctlly developed veins and impregnations. The former type, concretions, is connected with argillaceous or marly deposits of the Malm. (Kimmeridgian-Bononian), and usually of its higher parts. As example we may consider the occurrence of pyrite in the Jurassic of Pomerania, known from the quarries in Czarnogłowy and Świętoszewo (M. Podlaszecka, 1955).
