In this article recent developments in luminescence dating are described, together with the implications of these developments for the application of the various types of luminescence dating techniques now available. In particular, the development
of optically stimulated luminescence (OSL) techniques has had a profound effect upon the field, enabling younger materials to be dated, increasing the diversity of depositional environments that can be dated, and allowing the development of novel methods of age
Les élections générales de 1996 en Inde : géographie politique

Cet article a été écrit à partir de l'analyse géographique des données concernant les dernières élections législatives en Inde, en avril-mai 1996. Il présente un matériel très vaste (en premier lieu des données officielles), qui reflète la situation
The Vedde Ash Bed (mid-Younger Dryas) and the Saksunarvatn Ash (early Holocene) are important regional stratigraphic event markers in the North Atlantic, the Norwegian Sea, and the adjacent land area.It is thus essential to date them as precisely
as possible. Both tephras are dated precisely by AMS analyses of terrestrial plant material and lake sediment at Kråkenes.

This paper explores the possibilities of dating landform exposure by determining the timing of karst initiation across the region. The extensive salt karst system developed in Mount Sedom salt diapir, Israel, during the Holocene, is used. Multilevel
vadose caves were C 14 dated using wood fragments embedded in alluvial deposits. The oldest date of each cave is used to constrain the age of the salt exposure.
Radiocarbon dating of glacial moraines using the aeolian biome: tests results at Bishop Creek, Sierra Nevada, California

This paper explores a new approach to the age determination of glacial moraines: radiocarbon dating of components of the aeolian biome, mostly fossil arthropods, that become entombed in the matrix of alpine moraines, at Bishop Creek, on the eastern

The ages of some tsunami deposits can be determined by optical dating, a key requirement being that the deposits are derived from sediment that was reworked and exposed to daylight by tidal currents, waves, wind or bioturbation during the last years
before the tsunami. Historical records and radiocarbon dating show that the sand at each of the 3 sites, near Tofino and Port Alberni on Vancouver Island, is 150 to 400 yr old than the optical ages. These optical ages support the hypothesis

+The results of a luminescence dating program involving 78 samples of material from 9 sand ramp complexes have enabled recognition of regional and local patterns of sand accumulation in the Eastern Mojave Desert. The study area extends from Lake
Manix, in the west, to the Colorado River, in the east. The periods of accumulation have been identified on the basis of quartz TL dating, and potassium feldspar TL and IRSL dating. The continuity of sand supply to potential deflation areas is seen
