One of the greatest remaining problems in modern volcanology is the process by which volcanic eruptions are triggered. It is generally accepted that eruptions are preceded by magma intrusion [Sigurdsson and Sparks, 1978]. The degree of interaction between previously ponded magma in a chamber and newly intruded magma determines the nature and rate of eruption and also the chemistry of erupted la...

Geothermal exploration targets large magmatic intrusions as heat sources because of their size, longevity, and amount stored energy, but shallow volcanic plumbing systems comprise numerous smaller intrusions, geothermal potential warrants consideration. Here, we evaluate the impact dykes sills on caldera-infill rocks. We present geological data geothermometry in eroded Breiðuvík caldera Northea...

Iron ore occurrences are situated on the south-eastern slopes of the Medvednica Mountain. They occur as discontinous, decameters long and 2-3.5 m thick bedded, poorly mineralized (15-35 % Fe) lenses. A narrow, 6 km long, ore zone strikes NE-SW from Tisova Peć to Pustodol-Adolfovac. It is spatially and genetically bounded to the basic volcanogenic-sedimentary series (SEDEX-type), metamorphosed i...

Gangrene of the skin is a very rare complication of chickenpox. Barenberg and Lewis (1927) saw one example in over 2,000 children and Wishik and Bullowa (1935) saw four examples in 2,534 children with chickenpox. The condition was probably first described by Stokes (1807), but was first discussed in some detail by Jonathan Hutchinson in 1882. The latter's paper is notable for the beautiful repr...
