Book excerpt: "The major purpose of this study was to examine in detail the anomalous transgressive "boundary" sandstones which generally are present at formation boundaries throughout the Parras and La Popa basins. These extensive sheet-like sandstone bodies are massive, resistant units up to 20 m thick and up to 25 km wide that form the cap of mountains and hogbacks. These are anomalous units because transgressive deposits thicker than 5-10 m are rare in ancient deposits although they are well-documented for some Holocene deposits. For example there are no known thick transgressive deposits in the well-studied cyclic transgressive-regressive sequences in the Cretaceous rocks of the Rocky Mountains. McBride and others (1975) previously interpreted these boundary sandstone bodies to have been laid down as thick transgressive or regressive blanket deposits as the shoreline moved back and forth across the basins in response to variable basin subsidence and sediment input. In order to clarify this interpretation, we selected deposits formed during the latest part of the first deltaic progradation represented by the Cerro Huerta Formation, and at the beginning of the first marine transgression represented by the Cañon del Tule Formation for detailed study"--Leaves 3-4.

This book was released on 1979 with total page 232 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sandstone units of the Upper Cretaceous San Miguel Formation in South Texas are wave-dominated deltaic sequences deposited during a major marine transgression. San Miguel sediments were deposited in the Maverick Basin within the Rio Grande Embayment. Cross sections and sandstone maps reveal that during deposition of the San Miguel Formation, the Maverick Basin consisted of two subbasins. A western subbasin received sediments from the northwest; the eastern subbasin received sediments from the north. Net-sandstone patterns show that the thickest parts of the sandstone bodies are generally strike oriented; where not eroded, updip sand-feeder systems are indicated by dip-aligned components. The San Miguel deltas vary considerably in morphology and make up a spectrum of wave-dominated delta types. Modern analogs of these San Miguel deltas include the Rhone, Nile, Sao Francisco, Brazos, Danube, Kelantan, and Grijalva deltas. Final sandstone geometries depended on three primary factors: (1) rate of sediment input, (2) wave energy, and (3) rate of sea-level change. Delta morphology was determined by all three factors, but the degree of reworking of deltaic sediments after delta abandonment was determined by wave energy and rate of transgression. The most common vertical sequences in the San Miguel coarsen upward from silt and clay to fine sand. Burrows are the dominant structures. The few primary structures are of small scale; large-scale cross beds are observed only in outcrop. Strandplain or barrier-island facies sequences, which prevail in most wave-dominated deltaic deposits, are incomplete in the San Miguel. In most places, only the lower shoreface is preserved. The upper parts of the sequences, which normally bear large-scale primary structures, were lost by marine reworking during subsequent transgressions. Intense burrowing destroyed any primary structures at the tops of the truncated sequences. Most of the San Miguel sandstones are arkoses. Cements include sparry and poikilotopic calcite, quartz overgrowths, feldspar overgrowths, illite rims, and kaolinite. The primary destroyers of porosity are the two types of calcite cement, which tend to completely cement the coarsest, best sorted, and originally most porous zones of the San Miguel vertical sequences. Zones of secondary porosity resulted from leaching of shell material, calcite cement, and feldspars. Laterally, the zones of either high secondary porosity or calcite cementation are unpredictable.

This book was released on 2012 with total page 125 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Santonian-Campanian Eagle Formation in south-central Montana was deposited along the western margin of the Cretaceous Western Interior Seaway and is composed of a series of well preserved regressive and transgressive deposits. This study documents the depositional evolution of the informal lower member of the Eagle Formation exposed near Billings, MT. Detailed mapping and characterization of the internal stratigraphy, facies architecture, and bounding surfaces of the lower Eagle provide the basis for reconstruction of a paleodelta system that serves as a valuable reservoir analog within the Cretaceous Seaway and elsewhere. This study demonstrates that the informal lower member of the Eagle Formation in south-central Montana was deposited in a regressive to transgressive wave-dominated deltaic system. Within this deltaic succession the identification of five facies and four bounding surface types are used to establish a two-phase depositional history: 1) a regressive phase characterized by prograding pro-delta to distal delta front deposits emplaced below fair weather wave base but above storm wave base; and 2) a transgressive phase characterized by landward dipping proximal to distal shoal overwash fan deposits derived from combined-flow storm-generated turbidity currents. A maximum regressive surface (MRS) separates underlying prograding deltaic deposits from downlapping shoal overwash fan deposits above. Shoal overwash fan packages dip and stack en-echelon towards the paleoshoreline indicating landward migration of the shoal during delta transgression. A time-transgressive ravinement surface (TRS) developed on the basinward side of the transgressive shoal and migrated landward with the shoreline, truncating of shoal overwash fan deposits.

This book was released on 2014-04-15 with total page 233 pages. Available in PDF, EPUB and Kindle. Book excerpt: This overview of dinosaur discoveries in Mexico synthesizes current information about the geography and environment of the region during the Mesozoic when it was the western margin of the ancient continent of Pangea. The book summarizes research on various groups, including turtles, lepidosauromorphs, plesiosaurs, crocodyliforms, pterosaurs, and last but not least, dinosaurs. In addition, chapters focus on trackways and other trace fossils and on K/P boundary (the Chicxulub crater, beneath the Gulf of Mexico, has been hypothesized as the site of the boloid impact that killed off the dinosaurs). Dinosaurs and Other Reptiles from the Mesozoic of Mexico is an up-to-date, informative volume on an area that has not been comprehensively described until now.
