New approaches to high-resolution geological simulations

Written by

Geological models using Mishra and Haese’s workflow have improved predictions of fluid flow and fluid–rock reactions.

Geological and reservoir modelling are critical for geological exploration, resource extraction, and geoengineering projects. Current workflows and datasets record geological variations on metre or decimetre scales. However, many relevant geological structures exist at sub-centimetre scales. Dr Achyut Mishra and Professor Ralf Haese at the University of Melbourne, Australia – part of the international research consortium GeoCquest – have developed a […]

The attraction of New Zealand: Gravity anomalies of the Taupō Volcanic Zone

Written by

New Zealand’s Taupō Volcanic Zone (TVZ) is characterised by faulting, subsidence, voluminous volcanism, and geothermal activity. The gravity anomalies this activity produces have been mapped for more than 70 years. Through a new programme of collection and analysis of these data, Dr Vaughan Stagpoole, Dr Craig Miller and colleagues of GNS Science have revealed known collapse calderas in greater detail […]

Magma differentiation: The complex processes behind active volcanism

Written by

Active volcanism is prevalent across much of the Earth’s surface, yet the deep mantle and crustal processes that drive it are still being understood by geologists. Untangling the complex chemical relationships that arise from magma differentiation offer some clues as to the relationships between melting of mantle rock and crystallisation of molten magma to igneous rocks. Professor Vander Auwera at […]

Extinct giants, a new wolf and the key to understanding climate change

In this research article: Dr Meachen hopes to uncover the secrets of the mass extinction of the last ice age by re-opennig excavations at Natural Trap Cave (NTC) in North America

After its last excavation in the 1970s, a group of palaeontologists, genetics experts and cavers led by vertebrate palaeontologist and mammalian carnivore specialist Dr Julie Meachen of Des Moines University, have re-opened excavations at Natural Trap Cave (NTC) in North America. During this project, Dr Meachen hopes to uncover the secrets of the mass extinction of the last ice age […]
