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. By using various log and core markers, it is shown that there is one main sand at Ricinus. It cuts out the A sand in a broad (5 km) shallow (20-40m) scour, with increasing depth of scour toward the SE. The B sand continues below the main Ricinus sand as a continuous 'ragged blanket'.-from Author
