description | Systematic study of microfossil associations on the Krivi Potok section
(Gučevo Mt. area, NW Serbia) has been carried out to document and to refine
the Lower Triassic stratigraphic correlations within Alpine-Mediterranean
domain. Field investigation and laboratory process have enabled the
identification of lowermost Olenekian (lower Smithian) conodonts, ostracodes
and pyrite framboids. Two conodont zones are established in this region, in
ascending order they are: Pachycladina obliqua-Foliella gardenae Assemblage
Zone and Neospathodus planus Zone. A new ostracode species Paracypris ?
krivipotokensis FOREL n. sp. has been described, it co-occurs with conodont
Neospathodus planus within the Zone of the same name. The pyrite framboids
were formed within the ostracode carapaces after their death. The size
distribution of pyrite framboids supports the former suggestion that large
size (>6 μm in diameter) is not suitable for the reconstruction of seawater
redox conditions. |
