Using the West Australian craton as a model, but with reference to other shields, a highly generalized planation history of world-wide cratonic regions is traced from Proterozoic to present. Erosional unconformities and associated sedimentary veneers are found to be closely comparable in attitude and altitude, although progressively lower through time. The oldest, still nearly horizontal unconformity is Proterozoic, and subsequent unconformities tend to conform to this original cratonic… Expand
Development, sedimentation and economic potential of palaeoriver systems of the Yilgarn Craton of Western Australia
Abstract The Yilgarn Craton, covering an area of 720,000 km 2 is composed of Archaean rocks, dominantly granitoids, with narrow northerly-trending fold belts of older rocks. The surface of theExpand
Gondwanan (Late Jurassic and Cretaceous) palaeosurfaces of the Australian craton
Abstract Cretaceous, and especially Early Cretaceous, marine transgressions played an important part in the evolution of the Australian landscape. They covered at least 40% of the present AustralianExpand
Stepped surfaces and palaeolandforms in the northern Brazilian «Nordeste»: constraints on models of morphotectonic evolution
Abstract From the Parnaiba Basin to the Borborema Plateau (northeastern Brazil), the crystalline and sedimentary highlands and plains of the huge Jaguaribe–Piranhas amphitheatre are intersectedExpand
Evolution and decay of peneplains in the northern Lhasa terrane, Tibetan Plateau
The key issue of this thesis is the evolution and decay of peneplains, which are distinctive geomorphological structures in the southern area of the Tibetan Plateau. Additionally, evidence concerningExpand
Episodic burial and exhumation of the southern Baltic Shield: Epeirogenic uplifts during and after break-up of Pangaea
Cratons are conventionally assumed to be areas of long-term stability. However, whereas Precambrian basement crops out across most of the Baltic Shield, Palaeozoic and Mesozoic sediments rest onExpand
Relief and saprolites through time on the Baltic Shield
Abstract The relief of basement rocks in high latitudes has most often been interpreted as the result of glacial erosion, although over large areas its character of exhumed paleoplains has been knownExpand
Cenozoic landscape development within the Central Iberian Chain, Spain
Abstract In the Central Iberian Chain (Spain), covering an area of some 7400 km 2 , up to seven stepped erosion surfaces are determined from aerial photographs and field observations. These planationExpand
Phanerozoic denudation across the Kola Peninsula, northwest Russia : implications for long term stability of Precambrian shield margins
Contrasting views exist on the stability of the Earth’s shield regions over the last 1 Ga that have major implications for reconstructing erosion patterns on shields and the supply of sediment toExpand
Application of Low-Temperature Thermochronology to Craton Evolution
The view that cratons are tectonically and geomorphologically inert continental fragments is at odds with a growing body of evidence partly based on low-temperature thermochronology (LTT) studies.Expand
Post-Palaeozoic evolution of weathered landsurfaces in Uganda by tectonically controlled deep weathering and stripping
A model for the evolution of weathered landsurfaces in Uganda is developed using available geotectonic, climatic, sedimentological and chronological data. The model demonstrates the pivotal role ofExpand


Sequences in the Cratonic Interior of North America
The concept of major rock-stratigraphic units of interregional scope was introduced in 1948 (Longwell, 1949). It is now possible to restate the concept and to define more explicitly the sequencesExpand
A fluvioglacial and glaciolacustrine deltaic depositional model for permo-carboniferous coals of the Northeastern Karoo Basin, South Africa
Abstract With the northward retreat of the late Palaeozoic Gondwana ice sheet a series of glacial valleys, partially filled with diamictite, dominated the landscape along the northern edge of theExpand
ABSTRACT The Cobar Pediplain of western New South Wales, a vast gently undulating bedrock surface, contains abundant evidence of fluvial denudation since the middle-late Tertiary. Although networkExpand
Depositional History of the South Atlantic Ocean during the Last 125 Million Years
This study is based on a reconstruction of the paleogeographic and paleobathymetric history of the South Atlantic and on a standardized set of sediment and biostratigraphic data from all Deep SeaExpand
Age and origin of laterite and silcrete duricrusts and their relationship to episodic tectonism in the mid‐north of South Australia∗
Abstract Differential earth movements occurred during Eocene, Miocene, and late Caino‐zoic times. The faulting formed basins of sedimentation, led to dissection of land‐surfaces in some localitiesExpand
The separation of Australia from other continents
Abstract Palaeomagnetism provides the chief constraints on models of the separation of Australia from other continents. Palaeomagnetic studies suggest that the various cratons that comprise the mainExpand
Effects of Holocene climatic change on some tropical geomorphic processes
Abstract Man's interference with the landscape process places him in the role of a “paraglacial” agent: He tends to duplicate ice-age stresses such as deforestation, accelerated erosion, and climateExpand
Morphogenesis of Granitic Boulder Slopes in the Mojave Desert, California
Examination of quartz monzonite residuals in the western Mojave Desert indicates that current weathering of exposed granitic rocks is not renewing the boulder mantles characteristic of this region.Expand
Atlantic Sediments, Erosion Rates, and the Evolution of the Continental Shelf: Some Speculations
The volume of Triassic and younger sediment on and offshore from the Atlantic coast between Virginia and Nova Scotia can be estimated from the isopach map by Drake, Ewing, and Sutton (1959) ofExpand
Relationship between eustacy and stratigraphic sequences of passive margins
It is commonly thought that transgressive or regressive events that may have occurred simultaneously on geographically dispersed continental margins have been caused by worldwide sea-level rise orExpand
