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 […]
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’ […]
The Earth’s surface forms the interface between our human view of the world and the geology preserved beneath our feet. Variations in this surface are depicted on maps as contoured elevation data or graduated raster images (with colour scales referenced to elevation magnitude). These elevation models can be combined with geological maps to create a […]
I’m sure many of us have been strolling along the waters edge somewhere and imagined what will happen when sea level rise really begins to impact our coastal regions. What would happen to your favorite beach? How would that flash house behind the dunes be affected? Should we move further inland or build a house on […]
