Abstract
APPLICABILITY OF CUTICLE ANALYSIS IN STRATIGRAPHICAL-PETROGRAPHIC STUDIES OF COALS
Summary
The cuticle analysis, although not widely applied, is considered to be a highly useful paleobotanic method of coal studies by several researchers including Stach, Teichmüller and Weyland. Miocene brown coals are particularly suitable for application of this technique because of fairly close analogy to recent peatbogs. First attempts to use this technique were made in early sixties. First successful attempts to identify plant communities occurring in coals and to relate them to brown-coal lithotypes were made by Litke (1966) and Schneider (1966, 1969). Application of the cuticle analysis in coal studies appears highly advantageous as it makes possible to: (1) obtain some new data concerning the origin of brown coals (thanks to the fact that cuticle occurs in situ in these coals); (2) analyse plant communities composition of particular coal lithotypes; (3) identify the representatives of stratigraphically important family Lauraceae, difficult to identify by other paleobotanic methods; (4) establish precise age and to correlate of Tertiary floras; (5) improve our knowledge of ecological and particularly water requirements of fossil plants and, thus, to reconstruct the environment of origin of the plant-bearing coals ; (6) establish the degree of decay of parent peat material on the basis (taking into account) of the frequency of occurrence of the cuticle material in coal. The advantages of this method listed above and in the previous paper• (Juchniewicz, Prz. geol., 1973, no. 11) suggest that its application in stratigraphic and petrographic studies on brown-coal deposits will make it possible to obtain results highly valuable from the point of view of the current practice and science.
