This book was released on 2008-03-21 with total page 324 pages. Available in PDF, EPUB and Kindle. Book excerpt: Here, a diverse group of geologists and paleobiologists focus their attention on the richly fossiliferous Neogene stratigraphic sections of the Dominican Republic. They provide an updated geological framework and a series of novel studies of evolutionary stasis and change among different lineages and associated ecological communities. This collection of studies illustrates the immense potential of collaborative, multidisciplinary, and field-based paleobiological research.

Available in PDF, EPUB and Kindle. Book excerpt: The San Francisco Ridge is bounded by left-lateral strike-slip faults associated with the Septentrional Fault System. In this regard, the Septentrional Fault represents a major fracture in the northeast of the Hispaniola Island and separates an uplifted oceanic crust represented by the Cordillera Septentrional, and a "fore arc" basin, corresponding to the Cibao Valley. The San Francisco Ridge is a 50 km long by 11 km wide deformed and faulted asymmetrical anticline, interpreted as a "push-up" structure. It is located in the northeast region of the Hispaniola Island between the Cordillera Septentrional, to the north, and the Cibao Valley, to the south. The stratigraphy of the study area shows a sequence of limestone and dolomite with early Miocene age, calciclastic and siliciclastic mudstones with middle Miocene age and polymictic conglomerates with Pliocene-Pleistocene age that unconformably overlie the older and fined grained sedimentary units. The conglomerates are located in elevated areas of the San Francisco Ridge, especially in the northeast and northwest regions. The conglomerates have clasts of metamorphic and igneous composition, similar to the lithology reported in the Cordillera Septentrional. Topographic location of conglomerates in the San Francisco Ridge, and the origin of its clastic material, suggests that the San Francisco Ridge was in net contact with the Cordillera Septentrional before the late Miocene. Deposition of the conglomerates was associated with rapid uplifting of the San Francisco Ridge and erosion of the older sedimentary units, in response to compression exerted by the North American plate over the northeastern section of the Caribbean plate, occurred from late Miocene up to Early Quaternary. Based on the presence of a transpressive environment associated with an active strike-slip faulting zone, and the folding and tilting of the conglomerates along with the presence of a Quaternary "pull apart' represented by the Nagua valley, we conclude that the northeastern part of the Hispaniola Island is tectonically active and represents a major seismic hazard for the community of the Dominican Republic.

Magalhães and published by . This book was released on 2015 with total page 344 pages. Available in PDF, EPUB and Kindle. Book excerpt: Studies applying sequence stratigraphy to the Precambrian sedimentary record have been limited and have focused on low-resolution applications due to problems in preservation, deformation/metamorphism, and diagenesis. However, higher-resolution studies are possible where geometry, facies definition, and facies relationships are well-definable, such as that presented by the Mesoproterozoic Tombador Formation in the Chapada Diamantina (diamond-bearing plateau) Basin. Despite its very old age, this unit underwent localized very low-grade metamorphism, and the exposure and preservation are exceptional, affording a unique opportunity to observe changes at the sub-seismic scale (high-resolution sequence stratigraphy). Furthermore, this unit enables researchers to unravel the processes that dominated the deposition and understand their stratigraphic evolution, as few such pristine data sets are available anywhere in the world for that time interval. The data for this study were collected from several sources, including detailed and regional seismic-scale photo-mosaics; 1869.8 m of vertical section with a detailed facies description at a 1:40 scale; 697 paleocurrent readings; 1870 m of gamma ray (GR) logs with a 20-cm space sample; a 6.2-km ground penetrating radar (GPR) survey; and the description of 106 thin sections. The vertical description of the facies and stratigraphic sections, calibrated with the GR logs, the photo-mosaics, the GPR survey, and the petrography of sandstones allowed for the interpretation of the depositional systems, the identification of key stratigraphic surfaces, and the external geometry of the sequences. Higher-rank depositional sequence boundaries are placed at the base of the extensive amalgamated fluvial sand sheets or at the base of the alluvial fan conglomeratic successions that indicate basinward shifts of facies. The hierarchy system that applies to the Tombador Formation includes sequences of different orders, which are defined as follows: sequences associated with a particular tectonic setting are designated as 'first order' and are separated by first-order sequence boundaries where changes in the tectonic setting are recorded; second-order sequences represent the major subdivisions of a first-order sequence and reflect change cycles in the stratal stacking pattern observed at 1E2 m scale (i.e., 200-300 m); changes in the stratal stacking pattern at 1E1 m scale indicate third-order sequences (i.e., 40-70 m); and changes in the stratal stacking pattern at 1E0 m scale are assigned to the fourth order (i.e., 8-12 m). Changes in paleogeography due to relative sea level changes are recorded at all hierarchical levels with a magnitude that increases with the hierarchical rank. Thus, the Tombador Formation corresponds to one first-order sequence, representing a distinct sag basin fill in the polycyclic history of the Espinhaço Supergroup in Chapada Diamantina. An angular unconformity separates the fluvial-estuarine to the alluvial fan deposits and marks the second-order boundary. Below the angular unconformity, third-order sequences register deposition of unincised fluvial and tide-dominated estuarine systems and exhibit a lowstand fluvial sand sheet, an undifferentiated transgressive-highstand sand-rich floodplain, a transgressive estuarine, and highstand shoreface strata. In contrast, the third-order sequences above the angular unconformity are characterized by fining-upward continental alluvial successions composed of conglomerates overlain by fluvial and eolian strata; however, the data are inconclusive regarding whether these successions were downstream or upstream controlled. Hence, no systems tract nomenclature was used. Fourth-order sequences are clearly recognized at the third-order transgressive systems tract, and they exhibit distinct facies associations depending on their occurrence at the estuarine or fluvial domains. At the estuarine domain, they are composed of tidal channel, tidal bar and overlying shoreface heterolithic strata. At the fluvial domain, there are two types of fourth-order sequences: a) those preserved at the sand-rich floodplain, which are composed of cyclic successions of sand-bed braided or distal ephemeral sheetflood deposits capped by eolian sand sheet or mudstone layers, and b) those preserved at the tide-influenced braided fluvial sand sheet, which consist of cyclic successions of fluvial strata bounded by tide-influenced intervals. Fine grained intervals from shoreface heterolithic and sand-rich floodplain deposits constitute fourth-order sequence boundaries that at the reservoir approach, constitute the most important horizontal heterogeneity and hence the preferable boundaries of production zones. The criteria applied to assign sequence hierarchies in the Tombador Formation are based on rock attributes, are easy to apply, and can be used as a baseline for the study of sequence stratigraphy in Precambrian and Phanerozoic basins placed in similar tectonic settings.
