- Opis:
- The paper consists of the introduction, an outline of the geologic structure, a description of mineral resources and final remarks. The geologic structure of a region within the area of the Lednica castellary is presented on the basis of unpublished data from boreholes and the geological literature. Two geologic sections have been used in this study. One is very general by P. Karnkowski (1980 — Fig. 1), whereas the other by J. Dąbrowski (1985) depicts the structures of the Quaternary and Tertiary deposits along the line Wierzonka — Kowalskie — Jerzyn — Pomorzanowice — Lednogóra — Dziekanowice — Łubowo — Braciszewo — Skiereszewo — Gniezno (Fig. 2). The mineral resources that can be found inside the earth and on its surface are discussed in the following part of the article, i.e. in Chapter III. The paper also describes the potential accumulation of rock oil and natural gas during the Permian period. The substantial thickness of rock-salt in the Permian limestone (the upper Permian period) and anhydrites (the Permian limestone and the Triassic period) has been shown as well. The paper provides information on the occurrence of mineralized thermal springs in the Lias deposits (the lower Jurassic period). It has been stressed that their exploitation and utilization offer a chance of economic and recreational development of this region. Mention is also made of the occurrence of brown coal in Miocene deposits. Mineral resources occurring at the groud surface are described in every respect. First erratic boulders are characterized and Fig. 3 shows areas of their increased natural occurrence. A hypothesis has been put forward concerning the occurrence of calcareous sinter strata on the southern shore of Lake Lednickie. Note is also made of the discovery of calcareous sinter strata being now formed of Trląg on the western shore of Lake Pakoskie. Finally areas of probable occurrence of bog iron stone during the Early Middle Ages are selected (Fig. 4). Owing to appropriate utilization of mineral resources there is a chance connecting the tradition of this region with its economic and tourist development in future.
