(Steno, 1669) “aspect” or “appearance”
Can be genetic (fluvial facies) or descriptive (sandstone facies)
Lithofacies = a consistent lithologic character within a formation. E.g. an evaporite lithofacies
Walther’s law (1894) = facies that occur in conformable vertical successions of strata also occur in laterally adjacent environments.
