Figure 4. Center. Lithostratigraphic section of Leukopighi area.
(1)Pillow-lava with chert of the ophiolitic unit; (2) & (3) Upper Jurassic recrystallized limestone and calcarenite; (4) Lower Cretaceous limestone breccia and conglomerate; (5) & (6) Middle-Upper Cretaceous coarser grained bioclastic limestone and debris flow sequences rich in rudist bivalves fragments; (7) Santonian to Middle Maastrichtian bedded pelagic limestone; (8) Upper Maastrichtian pelitic flysch successions; (D) disconformity and bauxite horizon; (t)thrust.
Left. Photomicrographs of Upper Jurassic chlorozoan limestones.
(A) Hermatypic corals from well preserved coral boundstones.
(B) Bioclastic floatstone with fragments of calcareous green algae, corals echinoderms, oncoids, and small benthonic foraminifera. Non-skeletal grains are also detectible.
C) Rudstone with algal oncoids and fragments of calcareous green algae.
(D) Bindstone with Bacinella irregularis Radoicic.
Right. Photomicrographs of Upper Cretaceous foramol limestones.
A) Rudstone-floatstone with rudist fragments and large benthic foraminifera (orbitolinids). Corals, calcareous green algae, and non-skeletal grains totally lacking.
(B) Rudstone-floatstone with rudist fragments and large benthic foraminifera (orbitolinids) in crossed nicols. Along microstylolites bioclasts appear highly compacted.
C) Poorly sorted rudstone with bioeroded and micritized rudist fragments and large benthic foraminifera.
D) Pelagic foraminiferal wackestone with fragments of bioclastic packstone rich in shallow-water foramol skeletal fragments.
