Depositional Environments from Slope Aprons to Tropical Reefs - Tabernas & Sorbas Basins, Spain
This five-day field course offers an extensive series of outcrop examinations, field-based correlation, reservoir description, instruction and exercises. It aims to familiarize the student with the stratigraphy, shape, and scale of depositional bodies in small active Neogene basins. The value of sequence stratigraphic approaches, paleobathymetric analyses, and structural setting of the basin on predicting the large-scale character of the late Miocene deposits will be addressed in an appraisal and development context. The outcrop studies will illustrate the types of geological heterogeneity that occur in such sequences and show the geological processes responsible for these different hierarchical scales of variability.
Relaxed team exercises at the outcrops will enhance knowledge transfer. Three days working in Tortonian deep water environments studying deposits of mass flow processes and their interaction with slope geometries, assessing architecture of a sheet-like turbidites apron and contrast that with a scour/lobe apron. One day studying the effects of Tortonian-Messinian relative sea level in filling the Sorbas Basin with clastics and evaporites. Finally one day evaluating Tortonian to Messinian temperate water and tropical carbonates, the impact of relative sea level and the Messinian Salinity Crisis.
