Figure 2--Quartz-rich carbonate grainstone (lithofacies 1), St. Louis Limestone, Wade Allen 36-1. A) Core photo of a quartz-rich carbonate grainstone section with abundant inverse translatent stratification dipping at varying directions and angles up to 10°, 5612-5616 ft core depth. B) Close-up core photo of stylolites and inverse translatent stratification (showing horsetail structure), 5614.5 ft core depth. C) Thin-section photomicrograph of quartz-rich carbonate grainstone, 5613.8 ft core depth. D) Photomicrograph show translatent stratification with fine-grained quartz at the base and coarser carbonate grains at the top.
