Fucino Basin

<p>The interaction between sedimentation/erosion and faulting represents one of the most intriguing topics in landscape and tectonics evolution. Recently, several studies attempted to unravel this issue but only few of them have been able to document the feedback between faulting and sedimentary loading. Here, we focus on how the sediment loading/unloading influences the dynamic of the faults system taking as study case the Fucino Basin in Central Apennines (Italy). The Fucino Basin represents a remarkable case study with respect to the other main extensional basins in the Apennines, because of its large dimension, rectangular shape, significant sediment thickness and more important, its endorheic nature throughout its evolution.</p><p>We present a detailed structural analysis all around the basin, investigating the kinematic and geometry of each main fault strand. The slickensides analysis reveals multiples families of slip-vectors and timing of activity which suggest a changing from N240° to N200° occurred during middle-Pleistocene. Moreover, using a simple isostatic model, we estimate that up to the 30% of the total geological displacement of the faults, which overall ranges from 0.5 to 3.5 km, is related to the sediments loading/unloading. Then, we demonstrate a positive feedback between sedimentation and faulting which may also lead to a re-organization in fault-kinematic related to a significant increasing in the vertical stress. Finally, we propose a conceptual model to support the permanent endorheic configuration of the Fucino basin, mainly related to a fault-slip increasing and kinematic changing due to the sediment loading.</p>

Extensional Collapse

<p>Post-orogenetic extensional/gravitational collapse events constitute a relatively poorly understood tectonic process, which is responsible for the quick and effective dismantling of the thickened crust and topographic bulge of fold-and-thrust belt edifices. These events are also responsible for the accumulation of very thick post-orogenetic successions and, in case of active extension, may trigger moderate to strong earthquakes resulting in obvious seismic hazards (e.g., the 1915 Mg 7.0 Fucino earthquake in Central Italy, which caused 30,000 victims)</p><p>Here, we combine seismic interpretation coupled with well analyses, basin modelling and a thorough literature review, in order to compare an ancient and a modern example of study areas subject to post-orogenetic collapse. The Devonian-age Old Red Sandstones of north-western Europe and ?Plio-Quaternary fill of the Fucino intramontane extensional basin in the central Apennines (Italy) share several stratigraphic, depositional and tectonic characteristics. Both are characterized by remarkably similar seismic-stratigraphic architecture (with syn-depositional half-grabens) and maximum thickness of >1,500 metres. In the Fucino, the border faults associated to the main tectonic depocentres achieved maximum throw rates of 1,000-1,400 mm/kyr.</p><p>Both units comprise thick continental siliciclastic successions, dominated by lacustrine and alluvial to fluvio-deltaic facies. The facies architecture reveals a progressive transition from localized, fault-bounded depocentres to transgressive lacustrine successions in wider basins that are less reliant on the sole fault-driven subsidence. The studied units were deposited due to high and quick tectonic subsidence which took place very shortly after the end (or during?) of crustal shortening processes (respectively Caledonian and Apenninic orogenesis) and in a post-orogenic collapse context.</p><p>In both study areas, the sedimentation of the thick continental units are intimately associated to a polyphase inversion tectonics, with pre-existing inherited deep-seated discontinuities affected, in places, first by a positive and subsequently by a negative reactivation during the extensional collapse. A further element common in the two study areas, is a strike-slip or oblique tectonics occurring during or immediately prior to the extensional collapse achieved by the normal faulting. This has been interpreted as a consequence of the gradual rotation of the stress vectors around their axes, culminating in the relaxation of the horizontal compressive stress and the onset of the post-orogenetic extensional/gravitational collapse process itself. For example, in the Fucino Basin, maximum Plio-Quaternary sediment thicknesses of >1700 m occur in two tectonic depocentres, situated respectively to the north and east of the basin. In contrast, the south-eastern striking dip-slip border faults bounding the eastern edge of the Fucino show maximum slip rates in the Lower-Middle Pleistocene, with evidence (e.g., Gioia dei Marsi) for a very recent activity, possibly linked with the 1915 seismic event.</p><p>The study of post-orogenic extensional collapse by comparison of ancient and recent basins suggest that in these settings poly-phase tectonic inversion commonly occurs and promote multiple reactivation of inherited zones of weakness. The comprehension of the common and dissimilar features, may be fundamental to better understand the mechanism and evolution of post-orogenic chain reworking and for natural resources and geological hazards assessment, including earthquakes. The coupled analysis of an ancient and recent example enables just that.</p>

Background and objective: The productivity of fishing in marine waters provides an overview of the level of ability of the fishing gear used by fishermen to obtain optimal fish catches. This study aims to determine the productivity of fishing in locations around the construction of the coal-fired power plant, Jepara Indonesia. Methods: The method used is a descriptive method which is a case study. This research case is about annual marine fishery productivity by calculating Catch Per Unit Effort (CPUE), then predictions are made using simple regression analysis. Results: Based on the results of the study, a positive modeling trend (increase) was obtained for total fishery production, total demersal fishery production, and total pelagic fish production. Conclusion: capture fisheries productivity in Jepara waters is generally quite good and is not affected due to the development of Tanjung Jati coal-fired power plant B-Unit 5 -6. This is because it is not a fishing operation area for fishermen so there is no potential conflict with fishermen. Suggestion: The results of this study can be used by the Government of Jepara Regency in determining sustainable fishing policies and not overfishing

The Development Trend

Digital economy follows three laws — the Metcalfe’s law. the Moore’s law. and the Davidow effect, which are practically in line with China’s poverty-alleviation initiative by developing cultural tourism. The Moore’s law, however, is paradoxical in given contexts, and thus, we proposed the “reverse-Moore’s law” to analyze the current cultural tourism-based poverty-alleviation policies. The features of digital economy can be employed to support the cultural tourism-based poverty-alleviation work: the development trend of digital economy also coincides with China’s cultural tourism-based poverty alleviation initiatives. With the poverty-alleviation work at Chishui City in Guizhou Province as the study case, this paper made an analysis from the perspective of digital economy to confirm the practical and surreal significance of applying digital economy to China’s poverty alleviation endeavors.

<p>The study of integration policy is of particular relevance in an increasingly globalised world, since integration policy was shown to be important to the maintenance of social cohesion of immigrant receiving host societies (Papillon 2002, p. iii, Schugurensky 2003, pp.11-12, Friessen 2003, pp.187-191). This thesis sought to examine the fit of two explanatory theoretical models in explaining integration policy outcomes in two case study states, Ireland and New Zealand, during the period 1995-2006. More specifically, the thesis tried to determine whether the influence of the model of national membership adopted in each study case (civic membership in the New Zealand case and ethno cultural membership in the case of the Republic of Ireland) was able to anticipate the correct outcomes with regard to integration policies adopted during the study period, or whether political party positioning on socio economic lines was more important in anticipating integration policy outcomes. This assessment was conduct in light of apparent ‘fit’ of the respective theoretical models in each study case to integration policies enacted during the study period, in order to determine whether the theories that seem to fit the best anticipate the correct outcomes in each study case.  This was a salient question in light of the dichotomy in integration policy approaches in the two study states. Notwithstanding that both New Zealand and Ireland were immigrant receiving states during the study period, there was a marked difference between New Zealand’s approach to integration policy formulation and that of Ireland. New Zealand’s approach to integration policy was well structured and became more developed, while Ireland did not have a cohesive integration policy during the study period, relying instead on a reactionary approach composed of a collection of policy statements and ‘ad hoc’, reactionary policies.  As noted briefly above, the two theoretical models that were assessed for fit against outcomes in integration policies in the study states were the Brubaker theory of membership and the theory of political party positioning along the socio-economic left/right axis. The Brubaker theory suggests that integration policies are the outcome of national membership models (i.e. a civic or ethno cultural conception of national belonging), whilst the theory of party positioning along socio-economic lines suggests that integration policies are based on the influence of socio economic political party ideology. An investigation was made of the fit of the Brubaker membership models against that of the socio economic political ideology models in predicting integration policy outcomes in each respective case study. In addition, an examination of the interaction between the two explanatory theories was conducted, and an assessment made of whether this interaction had an impact on integration policy formulation. In exploring the interaction between two competing explanations for integration policy outcomes, this thesis aimed to facilitate a more comprehensive understanding for the reasons of the divergence in the approach to integration policy in the two case study states, and also a better understanding of the factors impacting on integration policy in general.</p>
