Figure 6.3. (A) Lacustrine-related reservoirs include coarsening-upward deltaic fill packages (after Coleman and Prior, 1982)
and fluvial and shoreface strata. (B) Shallow water playa lakes with highly fluctuating shorelines produce cyclical deposits of
potential reservoir sands and lake-deposited mud and clay (after Eugster and Hardie, 1975). See Figure 6.1 for explanation of
lithologic patterns.
