Book excerpt: Excerpt from Basic Geology of the Santa Margarita Area, San Luis Obispo County, California This investigation was based on the need for detailed geologic data on rock units and faults of the southern Coast Ranges, little of which was available in i96s. Little was known of the upper Mesozoic rocks of this region and data on Tertiary stratigraphy and lithology were rather general.

Available in PDF, EPUB and Kindle. Book excerpt: Basic Geology of the Santa Margarita Area By Earl W. Hart ------------------------------------------------------------------------------------------------------------------------------------------ Windham Press is committed to bringing the lost cultural heritage of ages past into the 21st century through high-quality reproductions of original, classic printed works at affordable prices. This book has been carefully crafted to utilize the original images of antique books rather than error-prone OCR text. This also preserves the work of the original typesetters of these classics, unknown craftsmen who laid out the text, often by hand, of each and every page you will read. Their subtle art involving judgment and interaction with the text is in many ways superior and more human than the mechanical methods utilized today, and gave each book a unique, hand-crafted feel in its text that connected the reader organically to the art of bindery and book-making. We think these benefits are worth the occasional imperfection resulting from the age of these books at the time of scanning, and their vintage feel provides a connection to the past that goes beyond the mere words of the text.

Book excerpt: Excerpt from Basic Geology of the Santa Margarita Area, San Luis Obispo County, California The Santa Margarita area of investigation lies astride the Rinconada fault, which divides the area into two distinct geologic and physiographic terranes - the La Panza Range to the east and the Santa Lucia Range to the west. The La Panza Range consists of Cretaceous granodiorite and adamellite with minor associated schist of the Salinian block. This is overlain by unnamed Upper Cretaceous sandstone and conglomerate and a relatively thin sequence of marine and nonmarine sedimentary rocks of Oligocene(?) to Holocene age. In contrast, "basement" rocks of the Santa Lucia Range consist of the chaotic Franciscan melange - a tectonic unit of probable late Mesozoic age. Overlying this are thrust plates of: 1) serpentinite and an intrusive complex of ultramafic-mafic rocks, 2) mafic volcanic rocks with chert, and 3) incomplete Great Valley-like sedimentary sequences of the Toro and Atascadero Formations of Late Jurassic to Late Cretaceous age. Tertiary marine and nonmarine sequences of sedimentary and volcanic rocks rest unconformably on the older units - the best preserved sequence being the Vaqueros, Monterey, and Santa Margarita Formations of Miocene age along the northeast margin of the Santa Lucia Range. Aside from being stratigraphically complex, most of the formations are severely faulted and folded as a result of two or more prolonged periods of tectonism. Late Mesozoic to early Tertiary thrust faulting is largely obscured by northwest-trending faults and folds of Miocene to Pleistocene (Holocene?) age. The principal structures are the Rinconada and "Nacimiento" fault zones and the intervening Santa Margarita syncline. The importance of the Rinconada fault is manifest in the highly contrasting rock units that are truncated by and juxtaposed along the fault. Correlation of a unique giant-boulder conglomerate (Simmler Formation?) and associated marine beds of the Vaqueros Formation with a similar apparently offset sequence of rocks 33 miles to the northwest suggests large-scale right-lateral displacement along the Rinconada fault and related connecting faults. Slivers of Franciscan rocks exposed along the southern segment of the Rinconada fault suggest that the fault is the local boundary between the Salinian and Franciscan (Nacimiento) blocks and that the "Nacimiento" fault zone lies totally within the Franciscan terrane in the map area. The ill-defined "Nacimiento" fault zone extends the length of the map area (18 miles) and appears to truncate the Rinconada fault at an acute angle at the east margin of the area. The "Nacimiento" zone consists of two principal fault elements - thrust and reverse faults that commonly dip southwest and near vertical faults. Although not unique to the map area, the southwest-dipping faults are in sharp contrast to the principal northeast-dipping faults reported to the northwest and southeast along the so-called Sur-Nacimiento fault zone (Vedder and Brown, 1968; Page, 1970a). At least 24 mineral deposits have been prospected in the map area, but only crushed and broken stone and sand and gravel have been produced in significant amounts. The Santa Margarita granite quarry is the principal source of high-quality aggregate and riprap In San Luis Obispo County.

Hall and published by Geological Society of America. This book was released on 2002 with total page 502 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
