Pg. 6 (fig. 2), 8 (fig. 4), 9, 24. See also 1941 [abs.], GSA Bull., v. 52, no. 12, pt. 2, p. 1954. Mercy sandstone lentil in Tierra Loma shale member of Moreno formation. Fine-grained, micaceous, massive, platy, concretionary sandstone interbedded with brown shale. Thickness about 190 feet. Occurs 70 feet below the top of the Tierra Loma shale member (new). Fossils (arenaceous foraminifers). Age is Late Cretaceous. On the basis of this mapping it is concluded that Anderson and Pack (1915) show base of Moreno formation in [Ortegalito] Creek some 1,800 feet stratigraphically lower than their type Moreno in Moreno Gulch.
