Some results of recent field work are briefly discussed as they pertain to the following topics: (1) north-south stratigraphic continuity of the Precambrian continental-terrace wedge, (2) stromatolite elongation, paleowind direction and global polarity during deposition of the Rocknest dolomite shelf, (3) evidence for primary aragonitic mineralogy of the Rocknest Formation, (4) attempted quantitative paleobathymetry of the upper continental slope, (5) eastward migration of foredeep flysch, (6) nature of basement involvement in Asiak Fold-Thrust Belt, (7) relation of thrusting to the foredeep molasse, (8) mysterious basement-involved cross folding of regional extent, (9) normal faults associated with late transcurrent faulting , and (10) the first reported minor leadzinc vein mineralization in Rocknest dolomite. Future field work is outlined.

Additional Information:© 1983 Geological Survey of Canada. Released 1983 01 01. Jean David, Mark Daynecka, Greg Eiche, Karen Pelletier and Janien Schwarz made an outstanding team of field assistants. Rene Brule was a skillful and reliable helicopter engineer-pilot. Winn Bowler and Martin Irving provided superior expediting, and we thank the staff of the Geology Office in Yellowknife for practical support. Spare parts from Joe's Garage were much appreciated. Adrian Camfield, Dan Krenz, M.E. Bickford and J. Fred Read visited, stimulated and encouraged us in the field. Tirrul's work on the structure of the externides will form the basis of a Ph.D. thesis to be submitted to University of California at Santa Barbara. Grotzinger's study of the Rocknest Formation will likewise constitute a Ph.D. thesis for submission to Virginia Tech. His work has been supported by a Geological Society of America Grant 2992-82, and a Grant-in-Aid of Research from the Scientific Research Society of Sigma Xi.
