Cyprus is one of the few areas Mediterranean where lower and upper Miocene coral-reefs occur in close proximity thus well suited to investigate how environmental geological changes affected reefs their associated shallow-marine facies. The prevailing conditions Terra Member Koronia are reconstructed here, using detailed microfacies comparisons skeletal, foraminiferal calcareous algal assemblage...

For a more accurate reservoir prediction of braided delta front, the method High Resolution Sequence Stratigraphy was adopted in Moxizhuang Oil Field with assistance Comprehensive Prediction Error Filter Analysis. J 1s2 divided into 2 fifth-order base-level cycles, 5 sixth-order turnaround surfaces rise to fall, and time-equal correlation shallow front achieved. Through study microfacies frame,...
