Ionic exchange tests have been performed on superficial wastewaters to remove ammonia by the use of a volcanic zeolitized rock from Lazio Region (Central Italy). The zeolitite (natural zeolite) is characterized by chabazite, phillipsite and minor amounts of sanidine, leucite and analcime. After preliminary column experiments in laboratory focused t...

Different synthesis experiments were prepared to determine the conditions and reaction times of the pyrometamorphic paragenesis found in this unit. The tests were carried out in a solid-state at 400-550-650-700-750-850ºC and atmospheric pressure, with relative proportions between the theoretical magma and carbonate rocks (1:1 to 1:05). The reaction...

The 23rd of April of 2015, the eruption of Calbuco volcano produced ash falling over certain localities. In San Martín de los Andes (~140 km from the vent), Argentina, two pristine ash samples were collected. The grain-size (Laser Diffractometry) of the particles is well-sorted (main peak at ~110µm diameter) and its fine fraction (<4µm) is signific...
