Plate 17 Steinplatte / Plattenkogel – Location at the northeastern Steinplatte slope and features of the profile at Plattenkogel hill. (A): Panoramic view on the north-eastern slope of Steinplatte reef showing the Triassic-Jurassic boundary at Pattenkogel hill (locality S1). (B): Lumachelle layer from Steinplatte/Plattenkogel locality. Detrital matrix comprises articulated Cardinia shells that were later dissolved and replaced by infiltrated sediments and blocky spar. Some cavity walls are lined by dark ferromanganese precipitates. (C): Section of the clastic sequence that fills up a sinkhole at locality S1 (Fig. 20, 90cm). Upper part shows intrapelsparites with angular clasts of red limestones, the lower half Fe/Mn- impregnated biosparites. (D): Close view on a cavity wall of the lumachelle layer (B) that is covered by “Frutexites” structures. Migration of manganese was probably induced by hydrothermal fluids. (E): Cement in a dissolution cavity of the lumachelle layer. Fungi-like meshwork suggests Fe/Mn-precipitation induced by filamentous microbes. (F): Ferromanganese crust at the contact of the lumachelle and the spiculite (Fig. 20 - sample no. 3b). Rippled Fe/Mn laminae with cauliflower-like shapes alternate with calcitic layers. From the top of the crust, “Frutexites” structures protrude into the surrounding spiculite matrix. (G): Enlarged view of the rippled laminae and tree-like “Frutexites” structures on top of the ferromanganese crust.
