Moose River Basin ABSTRACT Dispersed spore-pollen assemblages in fine-grained clastic sediments and coals from the Meso zoic of the Moose River Basin are listed and illustrated in part. Palynofloras from the Middle Juras sic Mistuskwia Beds in the subsurface of the central part of the basin are dominated by coniferous pollen and are comparable with the Middle Jurassic palynofloras of the western Canadian plains. Palynofloral assemblages from the Mattagami Formation are more diverse with many pterido phyte species represented. Approximately 160 spore-pollen species from the Mattagami Formation are used to delimit four interval zones spanning the Middle and Upper Albian. Spores and pollen from the lignites at Onakawana correlate most closely with the early Middle Albian Reticulatasporites-Concavissimisporites Zone. This zone has also been identified in the subsurface of the southern part of the Moose River Basin. Mattagami palynofloras correlate with those from the Potomac Group of the Atlantic Coastal Plain, the Swan River Group of Saskatchewan and Manitoba, the upper Mannville Group and lower Colorado Group of central Alberta, the Loon River, Peace River, and lower Shaftesbury Formations of northwestern Alberta, and the Logan Canyon Forma tion of offshore eastern Canada. Mattagami assemblages are entirely non-marine but recycled De vonian acritarchs are present in some horizons. INTRODUCTION Stratigraphic correlation and age determinations of nonmarine Mesozoic sediments of the Moose River Basin have been made possible using spores and pollen (palynomorphs) which are abundant in most sediments. Megaplant re mains were used for initial age determinations in the earlier studies of the Mattagami Formation (see Bell 1928; Radforth 1958; Verma et al. 1978) but, unlike plant microfossils, they are relatively rare and sporadic in occurrence. Thus, precise correlation was not possible. Palynology is now a routine procedure in stratigraphic studies of both sur face and sub-surface material. Industrial applications of palynology are wide spread in petroleum exploration, and as early as the 1920s the coal industry was utilizing spore-pollen work for correlation. Studies in Mesozoic palynology have proliferated since the 1950s with the increasing attention paid, in partic ular, to offshore as well as onshore basins for petroleum development. In North America, the following published palynologic studies are particularly relevant to the Mesozoic of the Moose River Basin (Table 4.1) In addition to the above, numerous smaller contributions have made sig nificant additions to knowledge of the biostratigraphy and taxonomy of palyno morphs from specific North American horizons and areas, some of which will be referred to below. Major works on the taxonomy and stratigraphy of spores and pollen from other parts of the world also have considerable relevance to the On tario Mesozoic in view of the cosmopolitan nature of some elements of the flora.

Mesozoic Palynology DESCRIPTION OF PALYNOFLORAL ASSEMBLAGES Middle Jurassic Middle Jurassic palynofloral assemblages have been reported by Norris (1977) from the top two-thirds of a sequence of 16 m of varicoloured clays and thin unconsolidated quartz sand horizons, informally termed the Mistuskwia Beds by Telford et al. (1975) (see also Telford, this report). These assemblages have only been reported from one locality to date; Ontario Geological Survey drillhole 75-03 (50 041'35"N, 82 048'08"W). Here, the Mistuskwia Beds are ov erlain by thick Pleistocene till, sand and gravel; their relationship to the Mat tagami Formation (Lower Cretaceous) is poorly known. The assemblages comprise more than two dozen species but are dominated by only a few bisaccate species (Alisporites bilateralis Rouse, Pteruchipollenites microsaccus Couper, Podocarpidites conuolutus Pocock) and species of Callialasporites and Cerebropollenites. Other elements of the assemblage are listed below and illustrated in Norris(1977) with the ranges of stratigraphically-restricted species indicated: Alisporites bilateralis Rouse Apiculatisporis sp. Araucariacites australis Cookson Araucariacites sp. Callialasporites crenulatus Pocock (Middle-Upper Jurassic) Callialasporites dampieri (Balme) Dev (Lower Jurassic-Lower Cretaceous) Callialasporites sp. cf. C. segmentatus (Balme) Dev Callialasporites trilobatus (Balme) Dev (Lower Jurassic-Lower Cretaceous) Callialasporites turbatus (Balme) Schulz (Lower-Middle Jurassic) Cerebropollenites carlylensis Pocock (Middle-Upper Jurassic) Classopollis minor Pocock (Middle Jurassic—higher Cretaceous occurrences are probably due to recycling) Classopollis sp. Classopollis torosus (Reissinger) Balme Cyathidites minor Couper Deltoidospora hallei Miner Exesipollenites tumulus Balme Kraueselisporites sp. Leptolepidites paverus Levet-Carette (Middle Jurassic) Perinopollenites elatoides Couper Perinopollenites sp. Podocarpidites convolutus Pocock (Middle-Upper Jurassic) Spheripollenites scabratus Couper (Middle Jurassic-Lower Cretaceous) Pteruchipollenites microsaccus Couper Spheripollenites psilatus Couper Taxodiaceaepollenites hiatus (Potonie) Kremp These assemblages were compared by Norris (1977) with palynofloras de scribed from western Canada by Pocock (1970). The greatest number of com mon species occurs in the Upper Gravelbourg of Alberta and Saskatchewan, 95
