摘要:ABSTRACT(#br)The Eifel Laminated Sediment Archive (ELSA), which comprises several cores from maar lakes, includes numerous tephra layers spanning the last 140 000 years. The sediment cores are dated by 14C and thermoluminescence as well as tuned to Greenland stadial–intersta...

摘要:ABSTRACT(#br)Itrax micro X‐ray fluorescence (μ‐XRF) core scanning is a non‐destructive, rapid approach to measuring elemental concentrations and their variability in sediment cores. As such, it records elemental signatures of tephra layers, which serve as correlation ti...

摘要:ABSTRACT(#br)Hekla volcano is a major producer of large, widespread silicic tephras. About 3000 years ago, the dominant eruption mode shifted from infrequent large (>1 km3) to more frequent moderate (<1 km3) eruptions. In the following two millennia ≥20 explosive silici...

摘要:ABSTRACT(#br)We review the current knowledge about Southeast Asian volcanoes and their eruption histories, and focus on identifying tephrochronologic markers representing major explosive eruptions in order to further future palaeoclimate and volcanological studies. Forty‐one...

摘要:ABSTRACT(#br)Tephra layers with Icelandic provenance have been identified across the North Atlantic region in terrestrial, lacustrine, marine and glacial environments. These tephra layers are used as marker horizons in tephrochronology including climate studies, archaeology and e...

摘要:ABSTRACT(#br)We explore developments in tephra science that consider more than chronology, using case studies of morphological transformations of tephra deposits. Volcanic processes and prevailing weather conditions determine the distribution of tephra deposits immediately a...

摘要:ABSTRACT(#br)Using contiguous high resolution sampling methods, we report the detection of a Glacier Peak volcanic ash from North America in Lateglacial Interstadial lake sediments in western Scotland. It occurs in close proximity to the Icelandic Borrobol and Penifiler teph...

摘要:ABSTRACT(#br)In Quaternary studies, tephras are widely used as marker horizons to correlate geological deposits. Therefore, accurate and precise dating is crucial. Among radiometric dating techniques, luminescence dating has the potential to date tephra directly using glass ...

摘要:ABSTRACT(#br)This paper presents the first detailed study of a late Pleistocene marine tephra sequence from the NW Pacific, downwind from the Kamchatka volcanic arc. Sediment core SO201‐2‐40, located on the Meiji Rise ~400 km offshore the peninsula, includes 25 tephras depos...

摘要:ABSTRACT(#br)A tephra layer offers an isochronous surface in sediments, thus serving as a key bed and/or an age marker. Recent high‐resolution sediment research (e.g. varved sediments) has revealed optically invisible tephra fingerprints and provided high‐precision tephra ag...
