Cardium Formation 2. Sand-body geometry and stratigraphy in the Garrington-Caroline-Ricinus area, Alberta - the ' ragged blanket' model.

This paper emphasizes sand-body geometry, and the lithology and sedimentology of the cores will be discussed in a subsequent paper. Correlation diagrams and isopach maps demonstrate that the upper (A) sand does not occur in long narrow strips, but forms a 'ragged blanket' sand of variable thickness over the entire area. The lower (B) sand also forms a 'ragged blanket' in the Ricinus-Caroline area, but is absent between Caroline and Garrington. …
