Middle Permian calcispongal cement reef on the Velebit Mt.

Ecological and morphological reef complex in central part of the Velebit Mt. was studied. Several superposed reef bodies indicate rapid sea-level changes. Vertical growth of the reef was aborted during sea-level falls, and resumed during sea-level rise. The reef evolution can be divided in 7 phases: 1. substrate colonization; 2. formation of primary reef framework with dwellers; 3. reef framework incrustation; 4. early lithification; 5.shallowing followed by weathering and erosion; 6. infilling of secondary reef porosity; 7. deepening followed by recolonisation, and, finally, burial of the reef.
