  • ranges were still submerged. Back-arc spreading extended from the Havre Trough to central North Island c.1.8 Ma. Eruption of ignimbrite began in central North Island c.1.1 Ma., and migrated to the Taupo Volcanic Zone c.0.6 Ma. Interrupted by a period
  • of inactive volcanism, the eruption revived in large magnitude c.0.33 Ma.

  • ou ferment des détroits. La Terre passe d'un régime d'englaciation unipolaire à un régime bipolaire à partir du Néogène, d'une circulation océanique zonale à la circulation thermohaline actuelle. A partir de 3 Ma, en relation avec la configuration des
  • Dénudation et longue durée (10-100 MA) : le cas des montagnes de marge passive du pourtour des océans Atlantique et Indo-Pacifique

  • Ardenne ; Belgium ; Downcutting ; Erosion ; Erosion rate ; Fluvial erosion ; Isotope analysis ; Quaternary ; Tectonics ; Vertical movement
  • Here, based on geomorphological observations, the AA. calculate the amount of river incision and interfluve denudation in the Meuse basin upstream of Maastricht since 0·7 Ma and show that the main response to tectonic forcing was incision

  • levelled the regional relief are identified by using geomorphological, geometrical structural and sedimentological criteria. Due to the Pampean faulting and uplifting during the last 10 Ma, almost all surfaces have been broken and tilted. The described

  • surfaces to constrain erosion rates of adjacent granitic uplands. By combining these techniques, they derive high-resolution records of erosion, relief production, and paleotopography in the Sierra Nevada over the past 5 Ma. These new records help to link

  • This study takes advantage of the large number of outcrops exposing the inner structure of La Gomera (Canary Islands), due to its inactivity during the last 2.5 Ma, to develop a conceptual groundwater model. Based on a volcanostratigraphic model, 5
  • hydrostratigraphic units have been defined that include 2 main aquifers and volcaniclastic deposits located between them that control the vertical movement of the groundwater. The island has been classified into 4 aquifer systems or water management units based
  • mass movement. Planting trees for cropping or logging, and removing understory vegetation is most likely detrimental to soil conservation.

  • d'évolution. L'étude a été menée dans le tronçon oriental des Pyrénées. L'A. y démontre une orogenèse saccadée, entrecoupée de phases d'arasement, ce qui rend quelque crédibilité au modèle davisien. Les vitesses d'arasement s'avèrent très rapides (6 à 8 Ma
  • Coefficient of stability of economic movements
  • Agrarian movement in India.
  • The Latin American barrio movement as a social movement : contribution to a debate
  • Social theory, social movements and public policy : recent accomplishments of the gay and lesbian movements in Minneapolis, Minnesota

  • Using the notions of locale, location and sense of place, as an interpretative framework, the A. argues that a spatialized analysis of conflict provides important insights into social movement experience. We are informed about the spatial
  • and cultural specificity of movements and about the cultural expressions of social movement agency. These arguments are contextualized by analyzing the Maoist insurgency of the Naxalite movement, which first emerged in India during the late 1960s.
  • Mass movement in the Himalaya : new insights and research directions
  • Mass movement in the Himalaya
  • Asia ; Geographical information system ; Geomorphometry ; High mountain ; India ; Mass movement ; Mountain ; Mudflow ; Natural hazards ; Tectonics
  • The processes of mass movement in the Himalaya have been described many times for the past two centuries. Recently, developments in a variety of fields have been introduced to assess the character of mass movement. Geomorphometry, remote sensing
  • , digital elevation models, and geographic information system technology are revolutionizing the study of mass movement in the Himalaya.
  • Slow soil movement as a global phenomenon
  • Climatic zone ; Creep ; Mass movement ; Slope ; Slope dynamics ; Soil ; Soil properties ; Vegetation
  • The slow movement of the soil depends on local factors (slope angle, moisture of the soil, vegetation cover) and on the latitudinal and altitudinal climatic zonal factors (temperature, precipitation). The rate of soil movement in the polar
  • (periglacial) zone is the highest on the globe. It is, as mass movement of the soil, three times higher than in the alpine zone. The soil creep processes in temperate climates are relatively small but greater than in the tropic zone. The smallest soil movement
  • Moving related to separation : who moves and to what distance
  • The AA. use data from the unique ASTRID micro database for Sweden, based on administrative information about the entire Swedish population. The methods are logistic regression analysis of moving, and OLS regression of the log-distance moved
