SPE 015

Petrography of the Mountain Lake Pipe, Grande Prairie Area, Alberta, Canada

Twelve samples rich in altered juvenile olivine from the Mountain Lake Pipe (holes ML95-1 and ML95-3) were studied for texture and mineralogy. Contrary to an earlier interpretation that Mountain Lake Pipe rocks are entirely extrusive crater-facies ... Show Abstract

Petrography of Ardley Coals, Alberta - Implications for Coalbed Methane Potential

The seams were sampled at mine sites west of Edmonton (Genesee, Highvale, Whitewood) and from outcrop sections in the Red Deer Valley, east of Red Deer. The seams were sampled 1) by full seam channel samples, which were subsequently analyzed by ... Show Abstract

Polyphase Deformation in the Canadian Shield of Northeastern Alberta

Two generations of structures can be distinguished in the granite gneisses and intercalated high-grade metasediments of the basement neiss complex, which has been shown to be Archean by radiometry dating. In some areas, D2 folds form parts of domes ... Show Abstract

Deformed Lower Cretaceous coal-bearing strata of the Grande Cache area, Alberta

The Lower Cretaceous Luscar Group includes a thin basal conglomerate (Cadomin Formation), a predominantly non marine sandstone and shale unit that locally contains coal (Gladstone Formation), a shallow marine shale and sandstone unit (Moosebar ... Show Abstract

Polyphase Metamorphism in the Canadian Shield of Northeastern Alberta

During the Archean metamorphic cycle, metasediments were metamorphosed under high pressure granulite conditions (M1). Coexisting garnet-biotite and garnet-cordierite pairs in the metasediments allows estimation of P-T conditions during the ... Show Abstract

Remnants of (Possibly Diamondiferous) Ultramafic Igneous Rocks in Bedrock of the Kakwa/Wapiti area, West Central Alberta

Bedrock sampling at 23 sites, heavy mineral separation and microprobing confirmed that indicator minerals of ultramafic igneous rocks are present in Cretaceous bedrock of the Wapiti area (NTS 83L). Para-magnetic heavy minerals (>3.3 SG) from ... Show Abstract

Coal Quality variation in the Cadomin-Luscar coalfield, Alberta

Abstract: Coal quality data were gathered from various sources and put in a geologic framework. The economic Jewel Seam forms part of the Lower Cretaceous Gates Formation and has a stratigraphic thickness of 10 m. Its depositional setting was on a coastal plain, well removed from marine clastic influences. Shortening of the strata by folding and thrusting amounted to 50 percent, often resulting in structural thickening of the Jewel Seam along fold hinges.Ash and sulfur are largely determined by the original sedimentary environment. Volatile matter, fixed carbon, carbon, hydrogen and vitrinite reflectance are determined by subsequent burial and to some extent by deformation. Vertical sequences with upward increase in ash and low ash zones through the center of the Jewel Seam can be explained by the original chemical environment of the swamp. Average finely disseminated ash is about 14 percent. In places, the disseminated ash content has increased by tectonic shearing. For mining purposes, the 2 m sampling interval of the Jewel Seam results in a good characterization of ash variation. Sulfur contents of the Jewel Seam are low compared to those of many other coal deposits and average 0.3 percent. Sulfur, which is mostly organic, often shows elevated values at the base, and to some extent at the top of the seam. Volatile matter, fixed carbon, carbon, hydrogen and vitrinite reflectance are largely determined by depth and length of burial, and to some extent by deformation.Rank of the Jewel Seam ranges from high to medium volatile bituminous, where the highest rank is found in the central part of the study area. The intersections of isorank surfaces and the Jewel Seam indicate components of syndeformational coalification. A good linear correlation between maximum vitrinite reflectance and volatile matter (dry and ash free) is observed. A contoured map of vitrinite reflectance predicts rank and volatile matter of the Jewel Seam for unexplored parts of the coalfield.
