(Kozłowski, Matuszczak 2021):
Studnik Hill (15º40’11”E, 50º49’32”N), exposure located c. 100 m to the southwest from the hill summit; in a rock covered by soil a pegmatite 47 cm in size and irregular shape was found. It contained a thin rim of granophyric intergrowths and typical feldspar-quartz filling. The central void (c. 16 cm dia.) was not visible, it was opened by crushing the rock. Accessory minerals included epidote, allanite, rutile, chlorite, calcite, natrolite (?), lévyne (?) and chabasite; groups of violet cubes (1.8–4.1 mm in size) of fluorite occurred in this assemblage; few of its crystals were included in the late transparent quartz. Close to this pegmatite (at a distance of 100–240 m) three blocks (23–41 cm in size) of basalt with TAS parameters (Le Maître et al. 2002) Na₂O + K₂O = 2.87, SiO₂ 47.66 wt% (authors’ data) were found. No parent basalt body could be traced there, but it is possible that they had come from a dike or more probably a sill now largely or completely eroded. This basalt blocks occurrence was known in the past (Berg 1921).
Note: Samples of pegmatites (Kozłowski, Matuszczak 2021) were collected in the years 1968–2006.
natrolite and lévyne (?) - probably wrong, visual (?) identification (laumontite or scolecite).
