Relationships between pre-eruptive conditions and eruptive styles of phonolite-trachyte magmas

Phonolitic eruptions can erupt either effusively or explosively, and in some cases develop highly energetic events such as caldera-forming eruptions. However, the mechanisms that control the eruptive behaviour of such compositions are not well understood. By combining pre-eruptive data of well studied phonolitic eruptions we show that the explosive-effusive style of the phonolitic magma is cont...

We present a 24-year-old woman with a skin eruption that had appeared a few mon...

The term was recently coined by Prose et al.1 to describe a dermatosis characterized by the sudden onset of a few to several bright red angioma-like papules with a different histopathology from the true angiomas.
