Book Description
Nearshore Marine Paleoclimatic Regions, Increasing Zoogeographic Provinciality, Molluscan Extinctions, and Paleoshorelines, California
Author: Clarence A. Hall
Publisher: Geological Society of America
ISBN: 9780813723570
Category : Science
Languages : en
Pages : 502
Book Description
Approximately 3000 middle and late Cenozoic nearshore marine molluscan taxa from western California are assigned to six time periods, spanning ~25 m.y. In this interdisciplinary study, western California is palinspastically restored for each of the time periods by backsliding and back-rotating large fault blocks or crustal units. Marine fossil assemblages are assigned to nearshore paleoclimatic regions or water masses within palinspastically restored California. In addition, this volume reveals positive feedback mechanisms between paleolatitudinal changes in sea-surface paleotemperature gradients and changes in the diversity of marine mollusks along the California coast through time; defines "equable" based effective temperatures; and analyzes extinction rates among macroinvertebrate marine taxa from coastal California and the possible causes of these extinctions. The late Paleogene to Neogene faunas reflect an increase in faunal diversity related to strengthened temperature gradients, greater extremes in sea-surface temperatures, reduction in temperateness, and the development of an embayed California coastline.

Middle Miocene Foraminifera and Stratigraphic Relations in the Adelaida Quadrangle, San Luis Obispo County, California
Author: Patsy Beckstead Smith
Publisher:
ISBN:
Category : California
Languages : en
Pages : 24
Book Description
The Salinas Valley region contains the type areas of the Monterey Shale and the Santa Margarita and Pancho Rico Formations as well as the type areas of the Relizian and Luisian Stages of Kleinpell. Only in and very near the Adelaida 7-1/2-minute quadrangle do strata representing these three marine units crop out in close proximity. In addition, beds that contain fossil marine mollusks of Paleocene age crop out in the quadrangle. Of particular significance in Coast Range stratigraphy are the wide range in Tertiary age fossils found in the Adelaida quadrangle and the geographic position of the quadrangle between the type areas of the Relizian and Luisian Stages of Kleinpell.
