The name of a lithostratigraphy, with the "kind" attribute specifying the lithostratigraphic unit-hierarchy (group, formation, member or bed). The entry at each level is free text for the local lithostratigraphy at that level in the hierarchy. If a single hierarchy is defined, it is assumed this is at the formation level in the hierarchy and kind=formation should be used for the entry.
Used to hold information about the stratigraphic units that an interpreted lithology may belong to. These are based primarily on the differences between rock types rather than their specific age. For example, in the Grand Canyon, some of the major lithostratigraphic units are the “Navajo”, “Kayenta”, “Wingate”, “Chinle” and “Moenkopi” formations, each of which is represented by a particular set of rock properties or characteristics.
