Member 11 experimental

A formal lithostratigraphic unit next in rank below a formation, and always part of a formation. It possesses lithologic properties distinguishing it from adjacent parts of the formation. No fixed standard is required for the extent and thickness of a member. A formation need not be divided into members unless a useful purpose is thus served. Some formations may be completely divided into members; others may have only certain parts designated as members. A member may extend from one formation to another. Specially shaped forms of members (or of formations) are lenses and tongues.

fr Une unité lithostratigraphique formelle d'un rang infiérieur à la formation et qui fait toujours partie d'au moins une formation. Il possède des propriétés lithologiques qui le distinguent des parties adjacentes de la formation. Aucune norme fixe n'est requise pour l'étendue et l'épaisseur d'un élément. Une formation n'a pas besoin d'être divisée en membres à moins qu'un objectif utile ne soit ainsi atteint. Certaines formations peuvent être complètement divisées en membres; d'autres peuvent n'avoir que certaines parties désignées comme membres. Un membre peut s'étendre d'une formation à l'autre. une membre peut être associé à une forme particulière telle qu'une lentille ou langue.
