SUMMARY Directional results, Thellier-type palaeointensity determinations and Ar/Ar ages are presented from volcanic units of Pleistocene age from the Hawaiian islands of Maui and Lanai. Twenty-nine non-contiguous lava flows were sampled on Lanai. Th

Tenerife basically consists of three Miocene shield volcanoes, the Anaga, the Teno and Central shield, as well as the Pliocene Canadas volcano. The temporal evolution and structural significance of each volcano with respect to the history of Tenerife

SUMMARY A catalogue has been compiled of existing published and unpublished archaeomagnetic directional data from sites in Germany. The data comprise 125 results dated mainly in the past two millennia. The stability of the natural remanent magnetizat

An extensive palaeomagnetic study was carried out on an approximately 250 Ma old reversed to normal transition of the Earth’s magnetic field (EMF) recorded in 86 volcanic lava flows of the Siberian trap basalts, North Siberia, Russia. In addition t

SUMMARY A new investigation of the thermal conductivity of the drill cores from the research drill hole Nordlingen 1973 in the Ries impact structure was conducted. The 1206 m deep drill hole pen- etrated 331 m of post-impact lake formations, then 275

The Palaeozoic units of Alpine Europe are generally accepted as having been part of the northern margin of Gondwana throughout the Cambro-Ordovician. By Permo-Carboniferous times, northern Gondwana had collided with Laurasia, forming Pangaea, but the

Palaeogeographic reconstructions of Pangaea during Permian times, based on palaeomagnetic data, result in major overlaps between Gondwana and Laurasia when choosing a Wegener type configuration (Pangaea A1 or A2). In order to reduce these overlaps, s

During stepwise thermal and alternating field demagnetisation experiments on Devonian and Lower Carboniferous carbonate and clastic rocks from the north-eastern part of the Rhenish Massif, Germany, three components of magnetisation (A, B, C) are iden

Rock magnetic properties of the Nile mud are reported. They indicate that the carrier of magnetization in the Nile mudis predominantly magnetite. Fourty air-dried ceramic samples made of Nile mud were manufactured to ceramics by stepwise heating to 7

A record of an excursion of the Earth’s magnetic field was found in a ∼14.3 Myr old lava sequence of the shield basalts from Gran Canaria (Canary Islands). The thermal and alternating field demagnetization of the samples from 14 subsequent lava f
