Table E. Facies and their component makeup

Facies values are determined by a combination of components and their mined values from word-based descriptions. Numeric textural, geochemical, and geophysical information held in _PRS data files. Values represent memberships to fuzzy sets, given as percents. A minimum of 30% component presence is required to trip a given facies, and a component may trip more than one facies. See _FAC files for actual data, and table C for component information. Facies notes presence only, not absence.
