AbstractThree unconformity-bounded formations of the Athabasca Group were examined in the Maybelle River - Net Lake area. The lowermost, Fair Point Formation (FP) is here subdivided into lower (FP1) and upper (FPu) conformable members. Fair Point Formation lower member comprises local, massive to planar-bedded siltstone beds interpreted as shallow lake deposits in fault-controlled paleovalleys, interbedded and overlain by matrix- and clast-supported pebble conglomerate and pebbly sandstone deposited by high-velocity streams forming a prograding alluvial plain. Fair Point Formation upper member (FPu) is massive to crossbedded, coarse-grained sandstone, also interpreted as a prograding alluvial plain. Manitou Falls Formation (MF) comprises a lower, crossbedded, medium- to coarse-grained sandstone (unit MFc) and an upper, ripple-crosslaminated, medium-grained sandstone (unit MFd). These are
equated to proximal units in Saskatchewan and record relatively low-velocity, distal, braided-river-system tracts. The uppermost, incompletely preserved Lazenby Lake Formation is massive, ripple-laminated, convolute-bedded, pebbly sandstone with sedimentary characteristics as in the Manitou Falls Formation, and records deposition by low-velocity, braided streams.
