Reconstructing the plinian and co-ignimbrite sources of large volcanic eruptions: A novel approach for the Campanian Ignimbrite
The 39 ka Campanian Ignimbrite (CI) super-eruption was the largest volcanic eruption of the past 200 ka in Europe. Tephra deposits indicate two distinct plume forming phases, Plinian and co-ignimbrite, characteristic of many caldera-forming eruptions. Previous numerical studies have characterized the eruption as a single-phase event, potentially leading to inaccurate assessment of eruption dyna...
متن کاملDeep magma transport at Kilauea volcano, Hawaii
The shallow part of Kilauea’s magma system is conceptually well-understood. Long-period and short-period (brittle-failure) earthquake swarms outline a near-vertical magma transport path beneath Kilauea’s summit to 20 km depth. A gravity high centered above the magma transport path demonstrates that Kilauea’s shallow magma system, established early in the volcano’s history, has remained fixed in...
متن کاملSpectral Sequence Motif Discovery
Sequence discovery tools play a central role in several fields of computational bi-ology. In the framework of Transcription Factor binding studies, motif finding algorithms ofincreasingly high performances are required to process the big datasets produced by new high-throughput sequencing technologies. Most existing algorithms are computationally demandingand often cannot suppor...
متن کاملNarsarsukite: a new occurrence in peralkaline trachyte, south Greenland
A flinty, spherulitic dyke of peralkaiine trachyte in a Precambrian dyke-swarm consists mainly of albite and aegirine. Within this, euhedral crystals of narsarsukite, NadTi,Fe)Si401o(F), occur as short prisms elongate parallel to c. This distinguishes them from all previously described narsarsukites, which have tabular habits. Minor phases present include micas, apatite, quartz, pectolite, nord...
متن کاملDiscovery and Development of a Style-Making Figure
Styles in the normal course of historical development change and evolve, and in the process of this movement and change, some poets play a vital role. These poets try to be inventive in order to escape banality and repeated and shallow literary traditions, and by creating a rift between themselves and former traditions they introduce new elements. These artists either create new figures o...
