EXPLANATION OF PLATE XII. 
Fig. 1. Alpha torhanite. Horizontal section, 60 diams. Showing closely packed algal colonies 
consisting mainly of gelosite with some retinosite bodies, set in opaque groundmass 
of humosite and matrosite. The botryoidal appearance of the compound colonies 
is well illustrated. Microslide No. 848, University of Queensland Collection. 
Fig. 2. Alpha torhanite. Vertical section, 60 diams. Showing flattened bodies mainly of 
gelosite, in opaque matrix. The collapsed central cavities of some of the algal 
colonies can clearly be seen. Microslide No. 849, University of Queensland 
Collection. 
Fig. 3. The Narrows oil shale. Horizontal section, 80 diams. Showing irregularly shaped, semi- 
opaque vascular fragments in organically stained clay matrix. Microslide No. 850, 
University of Queensland Collection. 
Fig 4. The Narrows oil shale. Vertical section, 80 diams. Showing laminated nature of the 
fine-grained rock. Quartz grains and some of the attrital material can be seen 
embedded in the clay matrix. Microslide No. 851, University of Queensland 
Collection.
