Narrows Graben

This paper compares aspects of geology and geochemistry of the oil shales contained in 4 basins The Narrows Graben... 

Mineralogy. The distribution of the major elements (expressed as oxides) in the main oil shale seams in three basins (The Narrows Graben, Duaringa and Hillsborough Basins) are listed in Table I. The most apparent variations are in the inorganic components of the carbonaceous units (Humpy Creek seam in the Narrows Graben brown-black oil shale and...

Plate 5. (a) Near-surface exposure of Max Rudolph fault (F) forming narrow shear zone in sand. Sets of precursory R- and R -shears on upthrown and downthrown blocks are truncated by fault (shears open upon drying of slope face), (b) Shale A in juxtaposition with shale B and underlying coal across Max Rudolph fault (F). Note the small graben feature, where shale is intersected by R- and R -shears. R-shear visible also upon upthrown side.
