Upper Cambrian in the Kielce Region of the Holy Cross Mts. — preliminary report.
S u m m a r y. The paper deals with new data from Lenarczyce PIG 1 well that drilled the Upper Cambrian deposits – hitherto unknown in the southern part of the Holy Cross Mts. The sedimentary record is composed of conglomerates, sandstones and mudstones that form up to 90-m-thick succession. Preliminary palynological studies indicate presence of a morphologically variable and well preserved Upper Cambrian acritarch assemblage. The well log can be divided into two parts due to differences in the tectonic style arrangement. The lower part (from bottom [= ? m] up to the depth of 128 m) reveal strong tectonic deformation demonstrated by the changing dips from horizontal through vertical to reversed. To the contrary, the upper part (above 128 m depth) shows lesser dips alternation and lack of folds. Both recognized structural complexes yield completely different acritarch assemblages.
