It is my first time attending the Goldschmidt conference and I am impressed by the variety of topics that can be accommodated under the umbrella of Geochemistry. From the Origin of Solar System and Mantle Geochemistry to Paleoclimate and Ocean Chemistry. But what drew my attention were sessions related to Medical Geochemistry and particularly topics […]

Conscripting plants and the microbial community for mineral exploration

Aug 18, 2017 No Comments by 888 views

Geologists have a great deal of geochemical tools for exploration of new mineral deposits. But, as most of the unexploited treasure is hiding at great depth, geologists have to invent and employ increasingly unusual tools to uncover new mineral resources. After seismic and electromagnetics, the potential of geomicrobiology is being investigated. Last Tuesday, Rachel Simister […]

Over the past few days, we have all heard our fair share of audience questions. As most of you may know, the main purpose of these questions is to enhance the audience’s understanding of the presented information. In many cases, this simply results in the need for the further explanation of a certain graph or […]

Goldschmidt 2017 sees the introduction of the pop-up talks; an exciting new initiative organised by three early-career scientists (Steffi Lutz, Kimberley Bitterwolf, and Alex Holland). Eleven students gave a series of 3-minute TED-style talks covering topics ranging from the origins of life to mine waste particles. Their mission was to convey a well-formulated idea in […]

How the Roman Empire can be linked to geochemistry

Throughout our geological education, we are taught to think in terms of deep time. To forget about weeks and months and focus on the millions and billions. However, when the time span of human history is taken into consideration, the geological time scale never seems to fit, discounting the Anthropocene of course. As a result, […]

Being on a ship for two months has its ups and downs. But when you’re drilling and recovering sediments that haven’t seen daylight for millions of years, you can bet both the ups and the downs are thrilling. My research involves the study of modern diagenetic (“rock-forming”) processes in order to better understand how to […]

Have you ever thought about what your house is actually made of? Before starting my Ph.D. I had never taken this question into consideration. However, for thousands of home owners across Ireland, the structure of their homes is under threat from the very stuff it is made of. Concrete. But why exactly is this commonplace […]
