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

Regional Evaluation of the Coalbed Methane Potential of the Foothills/Mountains of Alberta (Second Edition)

Abstract: Coal is present in the Alberta Foothills/Mountains in five zones: the Kootenay, Gething, Gates, Brazeau and Coalspur coal zones. For coalbed methane (CBM) evaluation purposes, they can be divided into shallow (less than 1000 m depth) and deep (greater than 1000 m depth) coal zones. The potential gas content of all shallow coal zones totals about 878 x 109m3 (31 Tcf)1 of CBM, which is considered an inferred, initial, in-place, coalbed methane resource estimate based on limited data. The limited amount of data on formation testing and measured gas content indicate that the inferred resource is bordering on the speculative category. The gas content of all deep coal zones (deeper than 1000 m) totals 2.8 x 1012m3 (about 99 Tcf) of in-place coalbed methane gas. Consequently, the total ultimate coalbed methane resource could be 3.7 x 1012m3 (130 Tcf). However, coalbed methane recovery from deep coals is generally not attempted because of the high cost of drilling and the low permeability that results from high overburden load and stress. The only (limited) Foothills coalbed methane production has been from the southern Alberta Kootenay Coal Zone, which is very prospective for coalbed methane production. The shallow Gates Coal Zone in the central and northern Foothills is also prospective, but needs to be better tested. The best potential for coalbed methane in the Coalspur Coal Zone is in the Edson area (Entrance Syncline and Triangle Zone). The Kootenay and Gates coal zones are not well defined in the northern part of Calgary (NTS 82O) map area. More work is warranted in this area to define these coal zones properly. It is recommended that 1:50 000 scale geological maps be updated and additional cross-sections displaying coal zones be constructed. Place Keywords 82o Theme Keywords coal
