The importance of geothermal energy as a source for electricity generation and district heating has increased over recent decades. Arsenic can be a significant constituent of the geothermal fluids pumped to the surface during power generation. Dissolved As exists in different oxidation states, mainly as As(III) and As(V), and the charge of individual species varies with pH. Basaltic glass is on...

The Kalkarindji continental flood basalt province of northern Australia erupted in the mid Cambrian (c. 511 505 Ma). It now consists of scattered basaltic lava fields, the most extensive being the Antrim Plateau Volcanics (APV) a semi-continuous outcrop (c. 50,000 km) reaching a maximum thickness of 1.1 km. Cropping out predominately in the SW of the APV, close to the top of the basalt successi...

Venus is a planet that is similar to Earth in terms of some important planetary parameters (size, mass, position in the solar system, presence of atmosphere) and different in terms of other, equally important ones (absence of an intrinsic magnetic field, large atmospheric mass, carbon dioxide composition of the atmosphere, lack of water, very high surface pressure and temperature). The surface ...

We examine the ascent of volatile-rich basaltic magma through a vertical dike that intersects a horizontal tunnel of comparable cross-sectional area to the dike and located 300m below the surface and initially lled with air at atmospheric pressure. This process is a simpli ed representation of some aspects of the possible interaction of a basaltic ssure eruption with a man-made tunnel, as part ...

DOI:10.17014/ijog.9.2.159-172 Ultic is the so il characteristics in soil taxonomy when argillic or kandic horizon found within depth of 125 cm with base saturation less than 35 % on overall upper 50 cm. The purpose this research to investigate whether ultic was developing from Pleistocene eruption Mount Tilu (basaltic parent materials), West Java, Indonesia. method used descriptive and comparat...
