Dmitry writes, “This is Co-bearing sphalerite, synthesised using gas transport method at 850C looks like the Christmas Tree. Although presented intergrowth of crystals was made in the laboratory, there are some natural samples, that comes from Africa. Green sphalerite from Congo can be used…

Photo of the Week

This amazing picture above was taken by Mikhail Varentsov, Lomonosov Moscow State University, Moscow, Russia. It can be found here. Mikhail writes “Melting summer sea ice is separated to pieces by the net of cracks, and their edges have amazing light-blue color, which is in contrast with white ice surface and deep blue sea water. Photo made during NABOS-2015 expedition.” What this photo really reminds me of is the recent records relating to Arctic sea ice…

Photo of the Week – Salt Coral

The photo posted below is a really cool one. Interestingly, enough I have been getting into podcasts lately. They are great during my bus ride to and from work every day. One of the podcasts that I like is Neil de Grasse Tyson’s Star Talk Radio. Anyway, the other week Star Talk had a pretty good discussion about salt and the role it has played in developing human history. Check out the episode in two…

Photo of the Week (Approximately)

The truly insane photo above shows “Different generations of calcite cements in Late Miocene seep carbonates (Piedmont, Italy; cathodoluminescence microphotograph)”. It was taken by Marcello Natalicchio, University of Hamburg, Hamburg, Germania  – Source. This photo was taken using a cathodoluminescence microscope which is both a standalone tool or can be an adaptation to a scanning electron microscope. In cathodoluminescence microscopy an electron beam is fired at the sample which causes it to emit light (luminesce).…

Welcome to Water Underground

A big welcome to the new EGU blog network blog Water Underground! Water Underground is the first geoscience blog that I am aware to be cross-hosted on both the EGU and AGU blog networks allowing it to reach people across the world. Water Underground, founded by Dr. Tom Gleeson, a prof at the University of Victoria, Canada, is a welcome addition to the EGU as it will cover groundwater, climate, and much more (it’s also…

Pilgrimage to Pompeii

One of the highlights of my honeymoon in Italy was our trip to Pompeii. Both my wife and I are big classics nerds so for us a visit to Pompeii had something of a pilgrimage aspect to it. For me, as a geologist, it was doubly impactful to see the effect of Vesuvius on the town. For the record, we got in a huge discussion about what actually constitutes a pilgrimage. It’s hard not to…

It’s Been a While

It’s been a long time since my last post. This is mainly due to the ridiculously busy summer I have had. The biggest thing was getting married, but the honeymoon, work trips and deadlines as well as working on a few papers kept me pretty occupied. I’m sad to say that blog updates dropped lower on my priority list then I would’ve liked. In any case, I am going to try to get back at…

Cruisin’ for Deep Sea Vents

My friend John Jamieson, who is now a prof in the geology department at Memorial University in Newfoundland and Canada Research Chair in marine geology and is also a former GeoSphere guest poster is currently on a research cruise near Fiji. John researches deep sea vents, aka. black smokers/seafloor massive sulphide deposits that are exhaling super heated water at tectonic plate boundaries around the world. These vents are modern analogues of the conditions in which volcanogenic…

Blast from the Past: It’s all about scales

It has often been said that geology is the study of scales. Time scales, large scales, small scales and many others. Indeed, one of the most crucial parts of any photo or map is the scale. Furthermore, geologic concepts can be applied from the planet scale to the atomic scale and every size in between. What confuses most people though is not only do we work in terms of huge size/magnitude variations but we also…
