Figure 64. Stratigraphic levels of palynomorph assemblages from Fruitland and Kirtland Formations in Ojo Alamo Sandstone type area. Geophysical log from Figure 33, palynomorph lists from Table 28; log explanations on Figure 33. Lower Fruitland palynomorphs approximately 75.1 Ma, upper Fruitland palynomorphs about 74.6 Ma, and upper Kirtland palynomorphs; samples at D level about 73.0 Ma, and at C level about 73.8 Ma. Majority of upper Kirtland palynomorphs from D sample level, just above Ash J level. Palynomorph-assemblage ages interpolated from ash-bed ages shown.
