#mineralmonday : sengierite

#mineralmonday : sengierite

#mineralmonday: your weekly* dose of obscure mineralogy, every Monday** [*not guaranteed; **or possibly Tuesday-Sunday] What is it? Sengierite: Cu2(UO2)2V2O8.6(H2O) What’s it made of? A few useful metals – copper (Cu), vanadium (V), uranium (U), plus oxygen (O) and water (H2O). So by ‘useful’ you mean ‘radioactive’? Pretty much. The main reason people have been ...[Read More]

Are mantle melts heterogeneous on a centimeter scale?

Are mantle melts heterogeneous on a centimeter scale?

The mantle makes up the majority of the volume of the Earth, but there is still a lot about it that we don’t understand. This is because we can’t observe it directly – forget ‘Journey to the center of the Earth’ – even our deepest drill holes (about 12 km deep) are merely tickling the surface of the planet (about 6400 km to the center). Most of what we know abou ...[Read More]

#mineralmonday : lithiophilite

#mineralmonday : lithiophilite

What is it? Lithiophilite, LiMnPO4 What’s it made of? Lithium (Li), manganese (Mn), phosphorus (P) and oxygen (O). The PO4 at the end of the formula makes this a phosphate mineral (phosphorus + oxygen = phosphate). What’s it’s structure? The way the different atoms are arranged in lithiophilite is described as orthorhombic, which means the crystal is built of lots of tiny cuboid- ...[Read More]

What I learned from chairing my first EGU session

What I learned from chairing my first EGU session

By Emily Bamber (PhD Student, University of Manchester) At this year’s EGU meeting I was invited to co-convene the GMPV 5.7 session ‘Magma ascent, degassing and eruptive dynamics: linking experiments, models and observations’. At first, I felt nervous, as a PhD student who has so far only attended and presented at a few conferences. Afterwards I felt happy to be part of a session which presents cu ...[Read More]
