WebCyclothem is derived from two Greek words: Oyclos, cycle, and thema, a deposit. Cyclothems are repetitive stratigraphic sequences that are unique to the Pennsylvanian and earliest Permian periods within the US … WebIf “pink partings” were accepted as indicative of subaerial exposure, three cyclothems (12%) would correspond to Fischer's ideal upward-deepening cyclothem, seven cyclothems (29%) are shoaling-upward, four (17%) are symmetrical and the remaining 10 (42%) are incomplete with both deepening and shoaling components.
