In het voorjaar van 1984 werd een tiendaagse wetenschappelijke reis gemaakt naar het gebied ten noorden van Chiavari, Ligurië, Noord Apennijnen, Italië. In het kader van het onderzoeksproject van de Vakgroep Structurele en Toegepaste Geologie naar de opbouw van de Liguride Apennijnen wordt gewerkt aan een geotraverse van Rapallo in het...

In the Cambro-Ordovician rocks of the Lys-Caillaouas region a conglomerate horizon is present of which the lower boundary can be considered as an angular unconformity. Observations of this unconformity are confirmed by an apparent cartographic unconformity, changes in orientation of delta lineations across the unconformity and a change in...

This report is written because of my practical training in Turkey in the period of the 25th of June untill the 20th of August. As a geophysical trainee I have worked for M.T.A. – Maden, Tetkik ve Arama -, a Turkish government founded company. The survey was done with the mini-Sosie method, a vibration system used here for shallow-land reflection...

Batchleaching is a low cost way of treating gold ore. First a basin is built with dirtwalls and plastic. Next the basin is filled with tailings together with some of the chemicals. Cyanide is put on top of the batch and a substantial amount of water is added, enough to start circulation. Water with dissolved cyanide slowly penetrates through the...

In july 1986, first and second year Mining and Petroleum Engineering students visited the east-cliff of Whitby during a field-trip to Northern England and Scotland. This cliffsection illustrated beautifully examples of a Middle Jurassic deltaic environment. Clearly recognizable are channels, crevasse splays and lagoonal or swamp deposits. The...

A detailed structural and stratigraphical field study of the Alpine basement as in the Middle and Late Miocene deposits of Western Crete made it possible to put better constraints on the tectonic processes, which took place in response to the roll-back of the Aegean plate from the Middle Miocene to Recent...

In order to interpret palynological records from the late-Quaternary and Holocene correct, a good understanding of pollen production and dispersal efficiency in tundra vegetation is necessary. Yet, only few studies in the arctic have dealt explicitly with the question of pollen transfer processes to lake sediments and aspects of representativity...

This report presents new whole-rock geochemical data on 45 samples from the upper part of the ~3450 Ma Hooggenoeg Formation of the Barberton greenstone belt, Kaapvaal Craton, South Africa. The study attempts to constrain the magmatic evolution of the felsic upper part of the Hooggenoeg Formation. Considerable controversy exists concerning the...

In the summer of 2001 a research project studying modem and historical aeolian deposition rates was carried out in the Kangerlussuaq-region, West Greenland. Modern deposition rates were monitored using 20 modified Tauber traps. The traps were placed on two perpendicular transects to assess the spatial variability in deposition rates. They were...

The Valley of Ten Thousand Smokes (VTTS) in Alaska was filled by a voluminous ash-flow tuff in 1912. In 1987 the chloride rich mid-valley thermal springs (MVTS) were discovered, indicating a persistent heat source at depth. A previous study proposed that the heat source is a cooling welded tuff unit (Keith et al., 1992). Discharge, temperature,...

This paper deals with mass movements resulting from hillslope instability and sediment yields of mass movements, derived from evidence of sedimentation rates in lakes. The purpose of this paper is to look into and compare different mass movement and lake sedimentation researches and to gain knowledge of the geomorphology of some mountain ranges...

It has long been noted that many earthquakes within so-called Stable Continental Regions (SCRs) occur within extended crust. The EPR1 (1994) definition of an SCR is a region that has not experienced any orogenic activity or anorogenic intrusions since the early Cretaceous and no rifting or major extension/transtension since the Paleogene. In...
