A Field Journey through the Messinian Salinity Crisis and Beyond

 
During the Easter holidays, 31 Part III Earth Science students and 8 demonstrators travelled to southeastern Spain (Almería) for the students’ final fieldtrip. The region’s complex geology offered something special for everyone. Over six days in the field, we moved through geological time and explored the diverse environments—from metamorphic basements and Miocene reef outcrops, to orbitally paced sedimentary cycles and gypsum beds, and on to turbidite deposits, volcanic centres, and strike-slip fault zones.

From magma to magnets: a summer of fieldwork in Greenland investigating critical metal behaviour in alkaline intrusions

This summer Carrie Soderman, Owen Weller and Charlie Beard headed to Greenland to investigate how metals critical for green technologies form.

Rare earth elements (REEs) are classed as ‘critical metals’ in modern society, meaning a group of metals and minerals that cannot be easily substituted in technology but whose supply is at risk. In particular, the REEs are a vital part of green energy transition technologies, such as the magnets that go inside motors for wind turbines and electric vehicles. Demand for these elements is therefore expected to increase rapidly in the coming decades.

Exploring the environments inhabited by Earth’s earliest animals in Namibia

Fossils of the Earth’s earliest animals appear abruptly in the geological record ~574 million years ago (Mya), and then suffer a mysterious decline in diversity just a few million years later ~550 Mya. Some researchers consider this biological change to be Earth’s first mass extinction event.

Cambridge at the Goldschmidt 2022 Conference

Alasdair Knight,  a second year PhD student in the Department of Earth Sciences, reports back from the 2022 Goldschmidt conference in the blog post below.

Alasdair can normally be found researching the chemical reactions that occur between greenhouse gases in Earth’s atmosphere and the rocks at Earth’s surface. These reactions are thought to have been important for keeping Earth within the correct temperature range for life to exist.

Arran 2022: best bits, as chosen by staff and students!

I can normally be found writing news stories or running outreach events for the Department, but this year I decided to dust off my walking boots and tag along to Arran with our first years to find out what makes this fabled Island so geologically exciting. Let’s just say it didn’t disappoint, and in the post below I’ve managed to condense down what — according to our students and demonstrators — makes this trip so special.
