Transient heat andor fluid mass exchange between the permeable fracture system and the surrounding relatively impermeable country rock can be treated in geothermal reservoir simulators using the “MINC” technique. This approach typically requires about an order of magnitude more computer time than the analogous “porous medium” problem. Under practical conditions, the problem can often be lineari...

The many thousands of Aboriginal rock art sites extending across Australia represent an important cultural record. The styles and materials used to produce such art are of great interest to archaeologists and those concerned with the protection of these significant works. Through an analysis of the mineral pigments utilised in Australian rock art, insight into the age of paintings and practices...

Intrusions of magma induce thermal aureoles in the country rock. Analytical solutions predict that the thickness of an aureole is proportional to the thickness of the intrusion. However, in the field, thermal aureoles are often significantly thinner or wider than predicted by simple thermal models. Numerical models show that thermal aureoles are wider if the heat transfer in the magma is faster...

The present study indicate that the copper mineralization in the area is of the nature of scattered sporadic occurrences of narrow lenticular and impersistent stringers and veins of copper-ore in vein-quartz and pegmatite traversing the amphibolite and garnetiferous mica schist country rock. The old workings for copper ore at Garimanipenta, which had a checkered history since early times, are b...

Review of the medical and audiologic literature indicates that MIHL occurs among musicians, with varying incidences ranging up to 58% in classical musicians and up to 30% in rock/pop musicians. In addition, studies show that musicians routinely face sound pressure levels (SPLs) in potentially hazardous ranges, extending up to 120-130 dBA only 3 feet from the speaker in amplified rock/pop bands,...

[1] A mechanism for explosive volcanic eruptions based on multicomponent phase equilibria modelling of four explosive volcanic systems is proposed. In each system, either isochoric or isobaric crystallization, where either crystals or crystals and exsolved fluid are chemically fractionated from melt, leads inevitably to near-solidus dynamical instability culminating in violent explosive eruptio...
