Combinations of subduction, accretion and extension along the evolving western Pacific margin (Eastern Gondwana) aided the formation of numerous gold deposits during the Phanerozoic. Active magmatism is recycling and concentrating elements as we speak with great examples of juvenile gold deposits forming in New Zealand’s geothermal zones. Global mineral deposit data available on-line through the […]
The QGIS2threejs plugin is an excellent, lightweight utility for the visualisation of surface data such as DEM. But what if your workflow requires the interpretation and visualisation of geophysical data? Fortunately there are a few simple tricks you can perform in QGIS and with this plugin to easily visualise other gridded data types. You can […]
This snapshot encompasses a large, highly populated area with over 120 Million inhabitants from the southern USA to the Caribbean and equatorial Brazil. Active volcanism is present in several volcanic belts from Mexico to Ecuador, as well as in the West Indies. Since 1900 AD some 57 separate volcanoes have erupted and of these 12 have […]
Since the Earth’s inception volcanoes have been releasing gases necessary for life to evolve. The associated process of recycling the Earth’s crust has concentrated natural elements that modern society relies on, from potash and sulphate for agriculture to lithium for technology and gold for commerce. As a result, communities across the globe have historically converged […]

As global population expands there is a proportional increase in the number of people living within areas under threat from natural hazards. A projection of trends from historical data suggests that over the course of the 21st Century global loss of life caused by earthquake-related events alone will extend into the millions. To minimise the […]

After driving through what seemed like endless, Oregon pine forest we arrived, in the snow, at a small car park high above shimmering blue water. Once out of the car the natural viewpoint opened widely to the north revealing high, rocky cliffs that encircled a vast lake. A conical, pine-speckled island broke up the lakes’ […]
