Lithofacies vs Facies - What

WebGenerally, geologists distinguish facies by the aspect of the rock or sediment being studied. [citation needed] Facies based on petrological characters (such as grain size and mineralogy) are called lithofacies, … WebThe middle member’s lithology is highly variable and consists of five distinct lithofacies. The unit is well-sorted (although bioturbation is common); well-cemented with calcite, dolomite, or silica; and light to medium gray in color. All lithologies within the middle member have low primary permeability and porosity. WebTechniques described in (Hami-Eddine et al., 2009) have shown the advantage of describing lithology kind and distribution using a probabilistic model. The probabilities estimated from well lithofacies can now be used for uncertainty estimation and generation of several lithology models. chloe search
