In 2001 the 433 m deep Messel 2001 bore hole was drilled in the centre of the Messel Pit, 25 km south of Frankfurt (Germany). Interdisciplinary, geoscientific results obtained from this drilling proved the origin of the circular-shaped basin as a maar-diatreme-structure beneath the surface. Recovered deposits consist of sedimentary rocks (0-240 m)...

This study presents rock magnetic properties measured on core samples of volcaniclastic units of the Messel maar-diatreme-volcano (25 km south of Frankfurt a. M., Germany) and explains the origin of downhole magnetic anomalies, performed during the drilling project in 2001.Magnetic behaviour of the erupted material (lapilli tuffs and diatreme-brecc...

Geophysikalische Untersuchungen im Gebiet der Grube Messel (25km südlich von Frankfurt) ließen schon vor einigen Jahren eine Maar-Diatrem-Struktur im Untergrund vermuten. Jedoch erst die gekernte Forschungsbohrung im Jahr 2001 bewies die Existenz eines durch phreatomagmatische Eruptionen gekennzeichneten Maar- Vulkans, der vor ca. 48Ma aktiv war. N...

... Juvenile parts are mainly basaltic ashes and spherical lapilli of 1-20 mm diameter. Parts of the accretionary lapilli have a nucleus of granodiorites, amphibolites, or titaniferous magnetite (Felder and Harms 2004;Nitzsche et al. 2006). These rocks formed the Messel Maar crater wall to varying degrees, with the youngest layers of the crater wall likely to have consisted preferentially of basaltic accretionary lapilli tuffs and ashes. ...
