What do Roman plumbing and Gondwana crust have in common?!

Aug 19, 2015 No Comments 2380 views

Janne Blichert-Toft’s plenary talk Tuesday lunchtime gave us an overview of what could be achieved with Pb isotopes with what she termed “Neo -plumbotectonics”. In her 45 minute talk she took us from Gondwana lower crust to Roman plumbing. Janne and her team have created a Pb isotope database for Europe which led to the […]

Martian meteorites old and new

Tuesday afternoon saw the Mars community come together for some reminiscing and new findings! The keynote talk by Allan Treiman was a fantastic “greyhead review” of past and more recent advancements in Martian geochemistry research, especially for those needing a refresher in Martian meteorite history and mission chronology! For instance I was surprised to learn […]

Yesterday in Terrace 1 was an absolute delight. I sat there for most of the day listening to some fantastic biogeochemistry. From weathering of rock to soil and sediment, to the profound influence of one man on global biogeochemistry.

Xenoliths, meteorites, and Mercury

The reputation of Goldschmidt is certainly well deserved, it is indeed huge, certainly the largest conference I’ve attended – four floors of the conference centre filled door to door with geochemists of all flavours! Sticking to my interest in volatiles in magmatic systems, Monday started with a trip into the mantle in session 14b. Ann […]

It came from the land

Morning folks, I have just spent the first half of my morning avoiding the rain in session 22c travelling back in time to the Precambrian. This is a pretty weird time period for me, being so drastically different to modern-day Earth, but the questions asked about it are so big and far-reaching, I can’t help […]

The critical condition of coral: awareness, and obligation of the scientific community

Aug 18, 2015 No Comments 1887 views

To say the conference has been animated over the past 27 hours would be a gross understatement. Acquisitive brains flit purposefully between the nerve centers of the hive, stopping only during brief but necessary trips via the coffee bars en route. Nearing midday yesterday we were invited to the grand auditorium at the heart of […]

Representative Sample

Aug 18, 2015 No Comments 1961 views

Yesterday was a great start to the meeting. Oodles of excellent talks and posters. A personal highlight was a presentation in theme 5 yesterday emphasised the difference between a “representative sample” and a sample population size which is representative. The discussion that followed, both in the questions and around posters, was focussed on the significance of micro- […]
