Book excerpt: Radiolarian faunas from the Upper Jurassic and Lower Cretaceous strata of the Great Valley Supergroup, Northern California Coast Ranges were studied. The Great Valley Supergroup was sampled at Grindstone Creek, Glenn County, California; for the Tithonian to lower Valanginian interval, and at McCarty Creek, Tehama County, California for the upper Tithonian to lower Albian interval. These two localities were chosen because of their biostratigraphic and geochronometric data. Ninety six species, including eighteen new species and one new genus, were identified from the micrite nodules. The radiolarian fauna is very diversified, but not abundant. Nassellarians dominate the fauna. Samples collected from the Grindstone Creek section of the Great Valley Supergroup contain Upper Jurassic (upper Tithonian) to Lower Cretaceous (upper Hauterivian) Radiolaria (Zone 4, Subzone 4 alpha to Zone 5, Subzone 5c). Micrite nodules from the McCarty Creek section yielded upper Tithonian to lower Albian radiolarian. U/Pb geochronometric data from Grindstone Creek section of the Great Valley Supergroup indicate an age of Berriasian. This study also describes a method of extracting well-preserved calcified radiolaria from micrite utilizing acetic acid.

Carter and published by Geological Survey of Canada. This book was released on 1988 with total page 124 pages. Available in PDF, EPUB and Kindle. Book excerpt: Extensive geological investigation of Mesozoic strata of the Pacific Rim is currently underway to determine the hydrocarbon potential of these rocks. Precise biostratigraphic control is essential for advances and substantial new information on the Jurassic biostratigraphy and taxonomy of Jurassic radiolarians from the Queen Charlotte Islands is presented in this report. Five new genera and 42 new species are described, most of which have restricted, and therefore useful, biostratigraphic ranges. A preliminary radiolarian zonation is proposed, calibrated with associated ammonite and foraminiferal faunas.

Available in PDF, EPUB and Kindle. Book excerpt: Field work carried out from 1947-1952 has resulted in the study of foraminiferal samples, with work directed toward obtaining as complete and chronologically diagnostic a faunal sequence throughout the Lower Tertiary in California province as possible. Preliminary reports have been presented from time to time, and this is a synthesis and revision of those reports and their conclusions, incorporating new data.
