Het vraagstuk over de oorsprong van de modern mens en de rol die de wadjak mens (Java) daarbij speelt

Storm, P. (author)

Op dit moment spelen twee modellen een rol ter verklaring van het ontstaan van de moderne mens (Homo sapiens), het “Lokale Continuïteits Model” en het “Noach’s Ark Model”. De twee fossiele Wadjak schedels van Java hebben een belangrijke rol gespeeld bij het ontstaan van het “Lokale Continuïteits Model” maar bij nadere bestudering van deze...

Hogbomite in sappherine-bearing rocks from the Bamble Sector, south Norway

Visser, D. (author), Thijssen, P.M.H (author)

Hogbomite is reported from two upper-amphibolite and granulite-facies, sapphirine-bearing, Al-Mg-Fe-rich and silica-poor lens-shaped layers within the Bamble Sector, south Norway. Primary assemblages, indicating peak metamorphic conditions of 773-844 °C at 7 kbar (Mg-Fe exchange thermometry), are spinel-sapphirine-biotite-gedrite, spinel-corudum...

Prestack time-time image map

Maaskant, A.E. (author), Fokkema, J.T. (author), Drijkoningen, G.J. (author)

In this paper we present a method for obtaining the pre-stack image map in the horizontal time – vertical time domain. Our approach is based on a data analysis in the double Radon domain, where the spatial complexity of the subsurface leads to a recognizable structure. Conventional velocity analysis is avoided by quantifying the scaling...

The onset of the Pindos Foreland Basin in Epirus (NW Greece)

Peeters, F.J.C. (author), Hoek, R.P. (author)

An integrated study of dinoflagellate cyst distributions, paleocurrent analysis and lithostratigraphy is carried out for nine sections in the Pindos foreland basin of northwest Greece, in order to generate a construction of the Pindos foreland basin during the Late Eocene and Early Oligocene. All studied sections comprise a conspicuous change in...

Perennial ·snow patches in relation to permafrost distribution: A study of permafrost in a changing climate and a first systematical mapping of perennial snow patches in the area of St. Moritz, Graubunden, Switzerland

de Graaf, E.H.J. (author)

Research on climatic change in the Alps focussed traditionally on glacier fluctuation. Recently research on permafrost gained more interest, because the climatic change affects large permafrost areas in the Alps. The permafrost reacts to a temperature increase in a complex pattern. Further research will be especcially necessary on the...

Neogene transpressive deformation in the Calingasta valley, San Juan province, West Argentina

Gast, J.J. (author), Reijs, J.P.J. (author)

In the central Argentinian Andes, the Northern part of the intermontane Calingasta valley has been studied by structural analysis of key outcrops. Within the Cenozoic fill of the Eastern side of the Northern valley, large windows of Triasic continental sediments outcrop. /Analysis of kinematic indicators have revealed that the overall...
