* Comparisons of oil analyses from different parts of the field indicate that Units A and B are not in fluid communication ([[:file:Mth14ch02f08.jpg|Figure 8]]).

Thus, Units A and B are separate compartments, and basinward progradation to the north indicates that reservoir compartments in Unit B are younger than those in Unit A ({{:file:Mth14ch02f05.jpg|Figure 5]]).
A common oil-water contact, tilted less than 1° (18.9 m/km, 100 ft/mi), exists between Unit A and South Yowlumne field, a lobate sandstone accumulation on the west side of Yowlumne field ({{:file:M14thch02f01.jpg|Figure 1]]). This common contact indicates depositional continuity, with Unit A and South Yowlumne representing adjacent depositional lobes. If the system progrades laterally to the west, as comparison to Unit B indicates, then the South Yowlumne Sandstones are younger than those in Unit A ([[:file:Mth14ch02f04.jpg|Figure 4]]).
