Talk:Platform basement

Should we distinguish between the platform and the basement, i.e., the basement as being the ancient, stable, interior layer of a continental craton composed of igneous or metamorphic rocks covered by a thin layer of sedimentary rock? I'm not sure about this. Most books, journals and dictionaries do distinguish between the two terms, but the term "platform basement" seems to take the ambiquity out of it.
