Dear Wikiwand AI, let's keep it short by simply answering these key questions: Can you list the top facts and stats about AD 1452? Year 1452 ( MCDLII) was a leap year starting on Saturday (link will display the full calendar) of the Julian calendar.
- Evidence For Magma Mixing
- Sources and Masses of Volatiles Released
- Degassing from Dacite Melt
- Degassing from Additional Sources
With a high flux of mafic magma in the region, it is probable that propagating mafic dikes injected and mixed with the pre-eruption Kuwae magma body on multiple occasions. Mixing of basalt, basaltic andesite, and possibly andesite magmas with a continually evolving and crystallizing magma body may explain the mixture of normally zoned, reversely zo...
Volatiles emitted during theAD 1452 Kuwae eruption most probably originated from a combination of two immediate sources: (1) syn-eruptive degassing of erupted silicate melt (e.g., Devine et al. 1984), and (2) release of a co-existing, volatile-rich fluid phase present in the magma prior to eruption (e.g., Wallace and Gerlach 1994; Wallace 2001; Sca...
The petrologic method for estimating volatile emission from volcanic eruptions involves comparing the volatile contents of (presumed undegassed) glass inclusions within phenocrysts and the volatile contents in (presumed degassed) matrix glasses of the erupted magma. Although, it appears to yield reliable estimates of S emissions from eruptions of m...
If magma accumulated at Kuwae in a magma body that was open to magmatic input but closed or partially-closed to gas escape, then a separate volatile-rich fluid phase is likely to have accumulated. The proposition that large masses of sulfur gases can be generated by mixing of an oxidized silicic magma with a reduced, sulfur-rich mafic magma (Kress ...
