Field study of the Rocknest Formation during 1981 and 1982, and laboratory study during the fall of 1982 has produced several interesting findings which are summarized in this report. Topics are: 1) subdivision of Rocknest Formation into ten informal members, 2) Rocknest shelf cyclicity and paleogeography, 3) shelf-to- slope transitions, 4) paleoclimate, and 5) evidence of possible microbial remnants in stromatolite bioherms of the Odjick/Rocknest transition beds. Future fieldwork is outlined.
