The early stages of transform margin formation are associated with crustal fragmentation and block rotation. restricted size the resultant microcontinental blocks precludes palaeogeographical reconstructions reliable estimations amount rotation they can undergo. An example considered here is Falkland Plateau. This located adjacent to Agulhas–Falkland Fracture Zone its westernmost province Islands microcontinent. position plateau islands prior Gondwana break-up remains contentious. study...
T he crustal structure along the passive margin of offshore Somalia has remained largely unknown, due to limited geological and geophysical data collection during long period political instability civil war. The extent information in area for many years been restricted regional-scale features defined from poor quality legacy seismic (Bunce Molnar, 1977) potential field (Coffin Rabinowitz, 1987; Rapolla et al., 1995). These observations allowed development early plate reconstruction models...
Commonly, intra-continental wrenching is associated with a high degree of crustal faulting and fragmentation. The resulting continental blocks can undergo vertical-axis rotations, which in turn lead to the generation intricate fault networks within along their boundary regions. Investigations into these structural complexities support understanding when how rotate, what position was prior transform margin formation. In case Falkland Islands Microplate (part Plateau margin), its between South...
Summary Reviewing previous studies and adding new paleomagnetic micropaleontologic data, this paper focuses on the Middle Miocene chronology stratigraphy in Dacian Basin area - a critical moment location – choking point between water masses of Eastern Central Paratethys. Firstly, it gives time-frame for one major tectonic, biologic basin evolution event intra-Sarmatian tectonic phase that took place above mentioned time interval. Secondly, proposes revision timing regional sub-stage...
Summary A recurrent difficulty encountered when picking first arrivals on deep seismic data is the very low signal-to-noise (SNR) ratio that characterizes far-offset traces. This has a direct impact accuracy of applied static corrections and results tomography. In order to remedy this problem, further enhancement these traces be done. effect can achieved using Refraction Interferometry (RI) method. According Bharadwaj et al. (2011) , long-offset virtual refractions obtained from near-offset...
Inversion of geophysical data is most often the last step in interpretation a model. However, inverted model has limitations that are important to acknowledge. Due nature data, encountered problems usually following: hidden or suppressed layers, nonuniqueness, equivalence and lack resolution parts In addition this, when resistivity surveys realized towns industrial areas, acquired also affected by coherent noise; these terms stand for influence infrastructural anthropic settings located...
Abstract Continental break‐up can be oftentimes associated with intracontinental wrenching that lead to the generation of transform margins and marginal plateaus. The phase accompanied by complicated processes, which result in heterogeneous structural crustal architectures. This makes understanding evolution such tectonic settings challenging. Falkland Plateau is an example a plateau where regional incipient stages Gondwanan continental mosaic types underlying its largest basin: Basin (FPB)....
<p>The palaeogeographic reconstruction of the Falkland Plateau transform margin in a Gondwana pre-break-up configuration has been subject debate for years. This is mainly due to uncertainty position Islands microplate. The islands were an extension south-east coast South Africa, being either i) part rigid fixed American plate or ii) undergoing vertical-axis clockwise rotation between 80° 120° along faults generated during initial stages fragmentation...
