There are major changes in the tectonic geomorphology of the Hikurangi margin along its length. In the north all the typical forearc, arc and back arc elements occur| in the south there are no arc or backarc elements even though the subducted slab
Neotectonics of the northeastern Basin and Range margin, western USA
Eleven backhoe trenches were excavated across six Quaternary fault scarps on the northeastern margin of the Basin and Range extensional tectonic province. Fifteen palaeoseismic events can be recognized, bracketed by radiocarbon or thermoluminescence
Tectonic geomorphology at a plate boundary : a transect across Hawke Bay, New Zealand in The geomorphology of plate boundaries and active continental margins.

In a transect across northern Hawke Bay from the Hikurangi Trench to the Taupo volcanic Zone there are four major tectonic domains, an accretionary slope, a forearc basin, a frontal ridge, and a backarc basin. Within each of these, landform
The AA. used abundant tree-ring samples in the Qaidam Basin to develop a new standardization method, i.e. total growth curve (TGC). They aimed to approach a theoretic curve of radial age trend by the deep sample depth and develop the standard ring

structures of the Sicilian Chain. This neotectonic system may be related to a W-E trending simple shear system, which controls the Tyrrhenian Basin development. - (NF)
Marine seismic investigations Southern Brazil margin
Les bassins Santos et Pelotas (marge du Brésil méridional) sont remblayés sous un épais coin sédimentaire pouvant atteindre 8 km sous le rebord de la plate-forme.
The Permian in the intracratonic basins consists of basal glacial to periglacial deposits overlain by marine and finally freshwater deposits. Basin shape was controlled mainly by NW and NE-trending structures that first appeared in the late
Carboniferous or early Permian and were intermittently active until the end of the Permian. The structures resulted from compression generated mainly by plate convergence on the eastern craton margin (Tasman Fold Belt) and to a lesser extent by taphrogenesis
of the sediments are clearly related to the margin of the basin and indicate its rapid subsidence. Tuffites in the sequence indicate volcanic activities in the hinterland. The development of the Argentine Neuquén Basin in the early Jurassique, shown
Turbidites and related sediments have been studied in Sinemurian, Pliensbachian, Toarcian, Aalenian and Bejocian strata of the Argentine Neuquén Basin. Mud flows, low energy and high energy turbidites and olistostromes can be recognized. Most
Devonian basin-fill histories of the Spanish Cantabrian Mountains and the Belgian Ardennes: a comparison
Emphasis is on the paleogeography reflected by lithofacies in the carbonate platforms on both basins. The Belgian carbonate platforms appear to have a Pacific faunal/particle affinity| they evolved from rimmed margin to knoll-reef rimmed ramp
the following features of the marginal zone: ablation end moraines, marginal edges of outwash plains, ridges and depressions left by the melting of the cores of ice-cored moraines, collar ridges of melt-out lake basins, and marginal kames and kame-and-kettle
On the basis of lithofacies and structural analyses of deposits and the spatial pattern of marginal zone features in selected areas, segments characterized by variable properties have been distinguished. Thus the Pomeranian Phase exhibits
Vertical crustal movements in the Tertiary of central East Greenland: a continental margin at a hot spot in Morphotectonics of passive continental margins.
Avant l'ère tertiaire, le centre est du Groenland était une surface d'aplanissement étendue dans les gneiss précambriens. Le rifting continental était amorcé avec la formation d'un bassin à la fin du Crétacé et le dépôt de sédiments clastiques suivi
Neotectonic movements on a passive continental margin: Salvador region, Brazil
, vertical movements of faulted blocks produced shifted Holocene shorelines. This neotectonism is related to the reactivation, during the Quaternary, of faults bounding the several crustal blocks which form the sedimentary basin. These deformations
The nature of calcareous deposits along pan margins in eastern central Namibia
This report describes a mainly petrographical study of calcareous deposits that are associated with pan basins in eastern central Namibia, aimed at establishing the mode of development of this common type of formation. Some observations are also
reported for two other calcareous formations that are exposed around several basins, documenting their difference in nature and origin with the deposits that are the main subject of this study. The results indicate that a lacustrine rather than purely
pedogenic origin should also be considered for calcareous deposits that commonly occur along pan margins in other parts of southern Africa.
