One thing all geologists want to know is the age of the rock they are looking at and the most common way of doing that is by looking at the fossil assemblage in the sediments. When working with a thin core from the bottom of the ocean as we do here we are obviously not likely to find a fossil horse or a dinosaur but instead we rely on microfossils that represent the ancient plankton of the ocean. read

Almost all of you will have seen the tragic news coming from Nepal. A magnitude 7.8 earthquake struck the region between Pokhara and Kathmandu, with at least 1000 killed at the time of writing. This number is likely to go up in the coming hours and days as the true extent of the devastation becomes apparent. Here we note some recommend reading and news sources on the event: UNISDR blogs from 2012 and today, giving valuable background information on the disaster risk reduction progress that [...]

When it comes to site selection problems or suitability models, the spatial Multi-Criteria Analysis (Weighted Overlay) is the most commonly used method. It’s easy, simple and popular. However, if it’s your first time to come across this method, it’s highly recommended to have a look at this link. After defining the problem you want to solve, the next 4-steps are followed to perform this method. Determine significant layers. Reclassify the layers. Weight the input layers. Sum up the [...]

Rhipidomella sp. brachiopod from Morocco

I've received some new brachiopod specimens from Morocco recently and this Rhipidomella sp. is one of them. It's a large, rounded shell with fine radial ribbing on the surface. The pedicle valve is a bit more convex than the brachial valve. The specimen comes from El Mrakib near Alnif in Morocco. I don't have specifics as to the formation (I suspect the Taboumakhlouf Formation) but the local rocks in which it was found are Emsian to Givetian in age (Devonian). I have not yet been able to locate [...]

It’s been a while since I wrote here on DG, but I’ve been busy writing on my own blog in Swedish. However, now it’s time to reveal something I’m pretty pleased with, that you maby can use as well. A simple (well reasonably so) method to extract geodata from panoramic photographs, by using open javascript libraries, some javascript of my own and a lot of head scratching. I won’t go into to much detail, but to make a long story short, I have not been able to find a [...]

Busy times on JOIDES Resolution. Our desire for core is being well met to put it mildly. Now we are greeted with the sight of many blue "end caps" smiling at us from the rack when we come to work reminding us of the significant backlog we are now building up and that we need to make a dent in soon if we are to get everything processed in time. Can be a bit intimidating at times. read

Continuing on of my coverage of the Dinosaurs and Geology in Pop Culture of the Salt Lake City comic conventions (Comic Con and FanX), we have the 2015 entry of FanX, which was held January 29th-31st, 2015. A bit of dinosaurs this time around. As with Salt Lake Comic Con a few years ago we have a company with the animatronic dinosaur suit walking around, however it appears to be a different company and a different type of suit this year around. This year it is from DinosaurEvents.com. I [...]

 SJ,NO,CN,BE,
This week’s Imaggeo on Mondays image is brought to you by Fabien Darrouzet, who visited the icy landscapes of Svalbard back in 2012. Whilst the aim of his trip was not to better understand the geology of the landscapes, his eyes were very much focused on goings on up, up in the sky, it didn’t stop him taking this still of the snow covered peaks. This picture was taken in Svalbard (78° lat.) in June 2012. I was there for one week in order to observe the transit of the planet Venus in front [...]
