“…Following the procedure of Shea et al (2011), only small-sized (0.1-0.001 mm) vesicles at the rim were considered, being representative of the final stages of rapid ascent prior to fragmentation. A melt surface tension of 0.09-0.17 N m −1 (Khitarov et al, 1979) was used to calculate a decompression rate in the range of 0.5-2.6 MPa s −1 , implying a final magma ascent rate in the range of 21-110 m s −1 . These calculated ascent velocities are 1-2 orders of magnitude higher than those measured for low-energy volcanic events fed by basaltic magmas, such as Hawaiian eruptions, e.g., Kilauea basalts (>1 m s −1 ; Gonnermann and Manga 2013; 1.4-1.6 m s −1 ; Klein et al 1987), and lava fountains, e.g., Mt.…”

Like a cannonball: origin of dense spherical basaltic ejecta

Cannonballs are rare spherical to sub-spherical eruptive products associated with basaltic explosive activity. The origin of cannonballs is still debated and subjected to a wide spectrum of different interpretations. In order to better understand the physicochemical mechanisms controlling the formation of these explosive products, we investigated the textural and chemical features of cannonballs from the Cerro Chopo monogenetic volcano (Costa Rica). These explosive products ubiquitously show a core domain with coalesced bubbles (30–36% porosity) wrapped in a dense rim domain with small, isolated bubbles (20–27% porosity). Both domains are identical in terms of bulk rock composition and mineral chemistry and are portions of the same magma batch. Results from combined petrological and thermodynamic modeling indicate that a low-viscosity (~20 Pa s) melt containing early-formed olivine phenocrysts (~9 vol.%) ascended from storage at a decompression rate of 0.5 MPa s−1 until it reached a depth of 4.5 km (equivalent to a pressure of ~150 MPa). While rising from depth to 4.5 km, the melt underwent rapid decompression (0.5–2.6 MPa s−1) and H2O exsolution, driving late-stage crystallization of the groundmass. The fast ascent velocity (21–110 m s−1) while rising between 4.5 km and the surface induced turbulent (Re >103), annular flow development in the uppermost region of the conduit. We propose that cannonballs represent blebs of fluid magmas that underwent shear-driven detachment from the annulus of magma lining the conduit walls at depths lower than 4.5 km. The formation of such cannonballs is dictated by magma transport dynamics of low-viscosity, phenocryst-poor, and volatile-rich melts that rapidly accelerate within the shallow conduit

“…For the production of wool fibers, a suitable range is from 1.0 to 3.0 Pa.s; the general temperature range was 1450–1550 °C according to the accumulation of experience [ 6 , 68 , 69 ]. For the production of continuous glass fibers, the suitable viscosity range is from 31.7 to 100 Pa.s according to the requirement of glass fibers [ 70 ].…”

Compared to basalt and glass fibers, the production of inorganic fiber from industry solid wastes is an effective method to not only save natural resources but also recycle waste resources. Because the preparation of the fibers requires high temperature treatment, the production process is associated with high energy consumption and high carbon emissions. How to resolve these problems is a current research challenge in this field. Herein, we reviewed the study progress on these fibers and further discussed the key factors determining their characteristics, including chemical composition, melt structure, and viscosity of melt. In production, the matching of solid waste blends containing enough total content of SiO2 and Al2O3, and a suitable amount of MgO and CaO, is beneficial to the structure control of the melt. The study found that the melt consisted of Q2 and Q3; and that Q3 content more than Q2 was more suitable for fiber production and its performance improvement. Such a melt structure can be achieved by controlling the degree of depolymerization and the temperature. New ultrasonic technology can shorten the homogenization time; its application is hoped to save energy and reduce carbon emissions. These conclusions will offer important guidance for the development of inorganic fibers from industry solid wastes in the future.

Suitability of Icelandic basalt for production of continuous fibres

The possibility of using Icelandic basalt for production of continuous fibres with presently known technology was investigated. One hundred and forty-five samples were taken based on selected field and petrographical criteria and further geochemically analysed. Additional sample discrimination using the geochemical results indicates that it may be difficult to find a suitable basalt for such production. However, minor modification to the composition of three samples is adequate to make them suitable. The viscosity of one specimen was further measured and found to be within the known limits for production of continuous fibres. It, therefore, seems possible that selected samples from the collection are suitable for production of continuous basalt fibres.
