...-precipitation in the sandstones. Illite fundamental particles from two sandstones buried at ~4000 m in the Tambora field next to the Handil field on the same near-shore anticline yield a mean K-Ar age of 15.7±1.6 Ma (2σ), which is younger than the stratigraphic age but still slightly biased by minute amounts...

... reservoirs are related to five structural trends of tilted blocks oriented sub-parallel to the Cabo Frio fault system: Tambora, Waimea (Tubarão Azul field), Fuji, Illimani, and Pipeline/Etna ( Fig. 8 ). The strike direction of faults is northeast/southwest. This structural pattern follows the same fault...

Perhaps nowhere on Earth are deposits of such supereruptions more prominent than in the Snake River Plain–Yellowstone Plateau (SRP-YP) volcanic province (northwest United States). While magmatic activity at Yellowstone is still ongoing, the Heise volcanic field...

... of the Little Ice Age, and subsequent large eruptions sustained it. Although climatic effects of eruptions like Pinatubo (Philippines) and even Tambora (Indonesia) lasted only a few years, it seems that coupling of oceans, sea ice, and atmosphere after larger eruptions can force decade- to century-long cooling...

Our study demonstrates the dangers of applying full-thickness approaches to even seemingly uniform fall deposits...

... presently observed. In the NE Japan Arc at the beginning of the JSO, the volcanic field migrated towards the oceanic side and the isotopic composition of magma temporally changed in the back-arc side of the system. This was likely caused by injection of hot asthenosphere into the mantle wedge and damming...
