Problem wizenu w synklinie kieleckiej

Abstract

PROBLEM OF THE VISEAN IN THE KIELCE SYNCLINESummaryFrom the Carboniferous of the Kielce syncline only the Tournaisian has been known so far, represented by siliceous-clayey sediments (Czarnów, Karczówka), marly sediments with trilobites (Karczówka), and calcareous material from the neptunian dikes of the Dalnia hill (M. Szulczewski, 1973). Recently new data on the Tournaisian and the newly-discovered Visean were collected by the present author and P. Filonowicz from the Czarnów settlement at Kielce situated in the northern limb of the syncline (fig, 1; P. Filonowicz, H. Żakowa, 1973).The Tournaisian deposits bear analogies to the Zaręby beds of the Łagów, Gałęzice, and Miedziana Góra synclines and of the Bolechowice area, Within the Visean, studied only fragmentarily, three lithological members have been distinguished (Tab. 1). Member 1 contains mainly cherry-red and greenish claystones with rare siltstones intercalations. In the upper portion siliceous claystones occur as well. Member 2 is represented by greenish-grey siliceous rocks. In absence of index fauna the age of members 1 and 2 is based on lithological evidence. The closest analogies exist between these members and the Lower Visean of the Łagów and Radlin sync1ines and of the Gorno area (H. Żakowa, 1962a; H. Żakowa, J, Pawłowska, 1961).However, the stratigraphy established is assumed only tentatively since certain features in the sediments of members 1 and 2 point to the upper part of the Tournaisian in the Łagów syncline. Member 3 embraces block shaly claystones and shales of the Lechówek beds type (H. Żakowa, 1962b). They contain index fauna and probably represent the Goa member. The selected fauna of the members 2 and 3 is demnostrated in Plate I.Despite the new material the distribution of the Tournaisian facies is not yet clear. Further studies are needed to solve the problem of the Lower Visean and the Tournaisian (Visean contact, and to determine the thickness of all the Carboniferous members.Owing to the identification of the Upper Visean the Carboniferous sequence in the western corner of the central part of the Świętokrzyskie Mountains has been supplemented and significant palaeogeographical data have been obtained.
