Photomicrographs of thin sections and drill core images from lithofacies 9–12 under plane-polarized light. a Shelly packstone–grainstone (LF9) from Schlattingen, 1154.54. The bioclastic bed is composed of micritized bivalves and significant amounts of intraparticle calcite cement (stained pink) and pore spaces (white). b Scoured packstone–grainstone (LF10) from Siblingen, 219.58 m. These beds are composed of micritized sediments, fragmented crinoids, and interparticle cement in white. c Drill core image of tempestite (LF10) with scouring and basal crinoidal lag, Schlattingen, 1159.19. d Laminated mudstone–wackestone (LF11) composed of marl-rich tempestites with crinoid veneers from Schlattingen, 1166.70 m. e Crinoid dominated wackestone–packstone (LF12) composed of large crinoids that are sometimes partially silicified (clear white patch in top right) from Böttstein, 192.97 m. f Drill core image of crinoidal bioherm sediments (LF12). Crinoids are extensively bored and the surrounding sediments are filled with fine gastropods and crinoid debris. Schlattingen, 1167.40
