Increased rates of large‐magnitude explosive eruptions in Japan in the late Neogene and Quaternary
Tephra layers in marine sediment cores from scientific ocean drilling largely record high-magnitude silicic explosive eruptions in the Japan arc for up to the last 20 million years. Analysis of the thickness variation with distance of 180 tephra layers from a global data set suggests that the majority of the visible tephra layers used in this study are the products of caldera-forming eruptions ...
متن کاملPliocene reversal of late Neogene aridification.
The Pliocene epoch (5.3-2.6 Ma) represents the most recent geological interval in which global temperatures were several degrees warmer than today and is therefore considered our best analog for a future anthropogenic greenhouse world. However, our understanding of Pliocene climates is limited by poor age control on existing terrestrial climate archives, especially in the Southern Hemisphere, a...
متن کاملLate Neogene and Quaternary Tectonics Associated With Northward Growth of the San Andreas Transform Fault, Northern California
Strain patterns within the forearc at a convergent margin adjacent to a passing fault-fault-trench triple junction show a systematic evolution. We describe late Neogene and Quaternary deformation in northern coastal California in the last 3 m.y. associated with the migration of the Mendocino triple junction. Deformation in the North American forearc near Humbolt Bay consists of a 30-km-wide zon...
متن کاملNeogene sapropels in the Mediterranean: a review
For 50 years the existence of sapropels (organic-carbon-rich sediments) deposited within Plio–Pleistocene sediments of the Mediterranean Sea has been known. Initially, research concentrated on material recovered in relatively short gravity=piston cores taken from the eastern basins where sequences were found to be well developed=preserved and had extensive spatial coverage. In the main, previou...
