Chronology and stratigraphy of the Fundy and related Nova Scotia offshore basins and Morocco based on core and outcrop

The Late Triassic age Blomidon Formation consists nearly entirely of massive gypsiferous mudstone and sandstones arranged into distinctive sand patch cycles, many of which show various salt dissolution features. Identical Late Triassic, cyclical, largely clastic facies are widespread in Morocco, on the conjugate margin to Nova Scotia, where Blomidon-like strata frequently pass in the subsurface into extensive thick and laterally extensive halite deposits. Similar deposits are also present on the Scotian, Newfoundland, and Moroccan shelves. The GAV-77-3 core, collected by Getty Mines in 1977 as part of a Uranium prospecting survey, covers nearly all of the North Mountain Basalt and the entire fine-grained portion of the Blomidon Formation. Two other cores, GAV-77-1 and GAV-77-2, were also collected in the same area, but cover less of the section. These cores nicely complement the spectacular outcrops along the Fundy shores and provided a basis for the development of a complete lithological and paleomagnetic reversal stratigraphy for the Blomidon Formation (Kent and Olsen, 2000). The paleomagnetic polarity stratigraphy of the outcropping Blomidon Formation is known only for isolated intervals, but in conjunction with lithostratigraphy allow unambiguous correlation registry between core and outcrop. Correlation of the GAV-77-3 core polarity stratigraphy with the Newark GPTS, also based on core, is fairly straightforward as is correlation with the Moroccan Bigoudine Formation of the Argana basin. These correlations demonstrate that the major cyclical wet climatic intervals in the Newark basin sequence can be recognized in the Fundy and Argana basins and should also be expressed in the intervening basins on the shelves. In addition they demonstrate the synchrony of major climate changes caused by the very long-term celestial mechanical cycles of a very large part of central Pangea

Cyclo-, Magneto-, and Bio-Stratigraphic Constraints on the Duration of the CAMP Event and its Relationship to the Triassic-Jurassic Boundary

Early Mesozoic tholeiitic flood basalts of the Central Atlantic Magmatic Province (CAMP) are interbedded throughout much of their extent with cyclical lacustrine strata, allowing Milankovitch calibration of the duration of the extrusive episode. This cyclostratigraphy extends from the Newark basin of the northeastern US, where it was first worked out, to Nova Scotia and Morocco and constrains the outcropping extrusive event to less than 600 ky in duration, beginning roughly 20 ky after the Triassic-Jurassic boundary, and to within one pollen and spore zone and one vertebrate biochron. Based principally on the well-known Newark astronomically calibrated magnetic polarity time scale with new additions from the Hartford basin, the rather large scatter in recent radiometric dates from across CAMP (>10 m.y.), centering on about ~200 m.y., is not likely to be real. Rather, the existing paleomagnetic data from both intrusive and extrusive rocks suggest emplacement of nearly all the CAMP within less than 3 m.y. of nearly entirely normal polarity. The very few examples of reversed magnetizations suggest that some CAMP activity probably occurred just prior to the Triassic-Jurassic boundary. Published paleomagnetic and 40Ar / 39Ar data from the Clubhouse Crossroads Basalt are reviewed and with new paleomagnetic data suggest that alteration and possible core misorientation could be responsible for the apparent differences with the CAMP. The Clubhouse Crossroads Basalt at the base of the Coastal Plain of South Carolina and Georgia provides a link to the volumetrically massive volcanic wedge of seaward dipping reflectors present in the subsurface off the southeastern US that may be part of the same igneous event, suggesting that the CAMP marks the formation of the oldest Atlantic oceanic crust

Synchrony between the Central Atlantic magmatic province and the Triassic-Jurassic mass-extinction event?

We present new data and a synthesis of cyclostratigraphic, lithostratigraphic, biostratigraphic, and published magnetostratigraphic and basalt geochemical data from eastern North America and Morocco in an attempt to clarify the temporal relationship between the Triassic–Jurassic mass extinction (∼ 202 Ma) and Earth's largest sequence of continental flood basalts, the Central Atlantic magmatic province (CAMP). Newly discovered zones of reverse polarity within CAMP flow sequences of Morocco have been hypothesized by Marzoli et al. [Marzoli, A., Bertrand, H., Knight, K.B., Cirilli, S., Buratti, N., Vérati, C., Nomade, S., Renne, P.R., Youbi, N., Martini, R., Allenbach, K., Neuwerth, R., Rapaille, C., Zaninetti, L., Bellieni, G., 2004.

Earth and Planetary Science Letters 228, 143–160.] as correlates of a very short, uppermost Triassic age reverse chron in the Newark basin, thus suggesting that much of the Moroccan CAMP was synchronous with or predates the Triassic–Jurassic boundary. Here, however, we explain these apparent reverse polarity zones as possible correlatives of poorly sampled lower Jurassic basalt flow sequences and overlying strata in eastern North America and lower Jurassic reverse polarity sequences recognized by others in the Paris basin. A revised Milankovitch cyclostratigraphy based on new core and field data constrains the duration of eastern North America basaltic flows to ∼ 610 ky after the Triassic–Jurassic palynological turnover event. Palynological data indicates correlation of the initial carbon isotopic excursion of Hesselbo et al. [Hesselbo, S.P., Robinson, S.A., Surlyk, F., Piasecki, S., 2002. Terrestrial and marine extinction at the Triassic–Jurassic boundary synchronized with major carbon-cycle perturbation: a link to initiation of massive volcanism. Geology 30, 251–254.] at St. Audrie's Bay to the palynological turnover event and vertebrate extinction level in eastern North America, suggesting a revised magnetostratigraphic correlation and robust carbon isotopic tests of the Marzoli–Knight hypothesis. We conclude that as yet there are no compelling data showing that any of the CAMP predated or was synchronous with the Triassic–Jurassic extinction event

Association between Family Involvement, Play, and Literacy Skills among Preschoolers from Low-income Families in Nigeria: The Mediating Role of Literacy Interest

During the early years, some children experience rapid growth in learning which provides a vital framework for their future success. However, other children especially those with poor literacy skills have to struggle very hard with reading and writing. Hence, understanding potential factors that improve literacy skills especially at an early age is highly desirable. Therefore, this study was designed to determine the direct and indirect relationship between family involvement and play with literacy skills through literacy interest.  This study employed a total of 394 preschoolers from low-income families aged between three and five years old with their parents in Nigeria.  The sample of this study was recruited using the proportionate stratified sampling technique. Path analysis revealed that family environment and play were associated with literacy skills both directly and indirectly via literacy interest. The findings have implications for parents and policymakers in educational sectors especially on how to make effective use of play and family involvement in improving literacy skills especially among preschoolers from a low-income family

An overview on data aggregation in IOT For wireless sensor network

in recent days, there is a increasing attention in employing wireless sensor network (WSN) technologies in different scenarios of Internet of things (IoT). On considering the massive smart objects growth with their application, there is a demand to analyze and collect their product data are appropriate of the major challenge. Data aggregation is one of the prominent approaches in the removal of data redundancy and energy efficiency improvement; in addition it enhances the Wireless Sensor Networks lifespan. As well, the competent protocol on data aggregation might decrease network traffic. As a detailed intention takes place in a detailed region, it may be recognized through too much sensor. Considering the main aspects and challenges of data aggregation in WSN, an assessment on various kinds of data aggregation approach and protocol were presented in this approach.
