Palynologie vzorků z vrtu Střeleč (V-800)
 Svobodová, Marcela
Borehole V-800 Střeleč was drilled in the area of sand-dominated delta sequences of the UNESCO Geopark “Bohemian Paradise” across the Coniacian/Turonian boundary and reached the lithostratigraphic boundary of the Teplice and Jizera Formations.(Čech, 2009). A relatively well preserved and diversified palynomorph assemblage was ascertained in grey claystones. Marine elements prevailed in all 23 studied samples. The composition of dinoflagellate cysts of Late Turonian age was partly comparable to that found in deposits of the Úpohlavy quarry (Svobodová et al., 2002, Uličný et al., 1996). The preservation of dinocysts and pollen grains in the upper part of the borehole (Coniacian age) was better than the preservation of palynomorphs from the lower part of the borehole (Turonian age). Chitinous linings of microforaminifers were abundant as well as amorphous organic matter. Biostratigraphically important angiosperm pollen of the Normapolles group were more common in sediments of the Coniacian age – Emscheripollis sp., Trudopollis sp., Plicapollis sp., Minorpollis sp.. Oculopollis sp. a.o. Tricolpate reticulate pollen appear rarely in lower part of the borehole.
