Volcanoes and Wines, Part 1

Volcano and Wine pt1 frontpage

Why talk about wine on the GMPV blog? Well, this geologist-favourite drink is not only good memories of the EGU General Assembly but also a topic that spans among all the GMPV categories. Indeed, wine composition, flavour, structure and quality are inevitably bound to the mineralogy and geochemistry of the soil, making it so common and appreciated since ancient times. And what gives us a nice comp ...[Read More]

Drilling in the deep: Project Mohole and the underground space race

The drilling derrick on DV Chikyu

The mantle makes up the bulk of Earth, extending from near the surface to the edge of the core 2900 km down. It constitutes 84% of Earth’s volume and has roughly 6 times the mass of Mars! Despite its impressive bulk, the mantle is almost everywhere covered by several km of crust. As a result we don’t have a lot of pieces of it that we can look at, hold or study. Those we have (e.g. xenoliths ...[Read More]

EGU GMPV Campfires: See you in September!

EGU GMPV Campfires: See you in September!

The GMPV Campfires will take a summer break and will be back in September! We would like to thank all the speakers for sharing their science with the GMPV community and all the attendees for participating and helping to improve the discussion so far. Our goal is to create a network of early career scientists, both within GMPV and among EGU Divisions, so your contribution is precious! Let’s k ...[Read More]

A lava for (almost) every colour

A lava for (almost) every colour

When we think about a volcanic eruption, one of the first things that come to our mind are lava fountains and flows with a characteristic bright orange and red colour. The colour of lavas can be associated with the temperature reached at the surface: dark red at low temperatures (475°C), orange at 900°C and white at extremely high temperature (>1150°C) (Kilburn, 2000). However, some places on E ...[Read More]
