Llopis Formation platform-top beds studied at Sierra de Seguilí: a: summary log of studied section showing overall, and bed-scale biofacies trends (External-Internal) up to boundary with overlying Almadich Formation (A. Fm.); b: exposure of rudist (ru) and coral (co) floatstone at 0–2.4 m in (a); c: thin section photomicrograph from lowest bed, showing Bacinella nodule containing orbitolinid and other bioclastic debris, and perforated by lined, geopetally filled bivalve borings; (d, e) upper half of bed at 5–6.5 m in (a), showing inferred regressive biofacies stacking (d), and (e) fractured vertical section through microkarstic cavities at top of bed, geopetally filled with orange-coloured crystal silt. Scale bars: b, e: 10 mm; c: 1 mm; and d: 100 mm.
