Occasional references to the relative tectonic instability of the Australian continent have been published over the last hundred years. Despite this, it was repeatedly claimed that the shield lands in particular were tectonically stable
, and as recently as this century reference has been made to a concept embracing a tectonically inert continent. However, analyses of seismicity and faulting and regional geological mapping revealed widely distributed tectonic forms and especially fault-related
In the present paper integrated stratigraphy and structural analyses are aimed at the description of a synsedimentary transpressional tectonic event, driving the onset and development of the Early Pliocene Lascari Basin, located NW of the Madonie
the timing of transpressional tectonic event in northern Sicily. A brief comparison performed between the data here presented and those coming from adjacent sectors of northern Sicily suggests that the transpressional tectonics in these sectors of the chain
Carbonate platforms bordering the Tethyan margins carry a distinct periodic signal that can be related to Jurassic-Cretaceous climate and eustatism. They yield a rich archive of information, including the tectonics affecting the platforms
deposits pertaining respectively to the Trapanese and the Sicanian successions, and a thick Oligo-Miocene numidian flysch body, crop out. A structural analysis reveals complex tectonic relationships between the Trapanese carbonate platform tectonic unit
(the Rocca Busambra carbonate ridge) and the overthrusting Sicanian deepwater carbonate (Corleone-Barracù) and numidian flysch tectonic units, outcropping around the carbonate ridge. - (NF)

linked to the direct action of tectonics at the macro-scale level, as in the case of the orientation of the principal valleys. Tectonics have also promoted the spread of gravitational phenomena. The glacial footprint is evident in the numerous inactive
The Medziphema intermontane basin developed in the schuppen belt of Nagaland, Northeast India, has been studied to understand its tectonic and geomorphic evolution on the basis of field evidence and morphometric parameters. Major part of the basin
The AA. chose the major valleys of the Adriatic foothills (central Italy), affected since Late Miocene by a differential tectonic uplift which is still active. In particular, (i) they applied the geostatistical analysis to reconstruct the original

reconstruction of the complex relationships between speleogenesis, tectonics and sea level fluctuations.
The A., a physical geographer, addresses climate change and feedbacks for Eurasia over longer (tectonic forcing, intermediate (Earth's orbital relations) and shorter timeframes, emphasizing that climates change more or less continuously in response

The surface of the Gömör–Torna/Gemer–Turňa Karst was largely formed by Pannonian or Pliocene pediplanation. Although this surface has been dissected by subsequent tectonic and fluvial processes, the present karst plateaus still preserve large pieces
and weathering features, the AA. discriminate between control by differential erosion and tectonic movements. They suggest that the stepped patterns of erosion surfaces represent a pre-glacial landform evolution related to the uplift of 2 antiforms along the west

It is unclear whether the Darling scarp is a rapidly evolving landform responding to recent tectonic and/or climatic forcing or a more slowly evolving landform. In order to quantify late Quaternary rates of erosion and scarp relief processes, the AA
, hillslopes with contrasting boundary conditions (actively incising channels versus noneroding landforms) were studied. Channel incision rates, which ultimately drive hillslope erosion, varied with precipitation rather than tectonic setting throughout
and the ability of the landscape to respond to tectonics decreases.
of accommodation space for sedimentation has previously been attributed to tectonic controls, but new investigations reveal that a more likely cause is progradation of coarse-grained tributary fans across the narrow river valley downstream of the main area
. The results have been represented in thematic maps, where landscape boundaries based on genetic notions coincided with neotectonic fault lines in several places. In order to make geomorphological and tectonic models correct the geological sediments of the high
