Imaggeo On Monday: S-C mylonite in the Calamita Schists (Island of Elba, Italy)

S-C mylonites developed in andalusite-cordierite micaschist (Calamita Schists) in the contact aureole of the Porto Azzurro pluton. The white layers are made of quartz, while the brown layers consist predominantly of white mica and biotite. Top-to-left (East) sense of shear. Read more: Papeschi et al (2017). Heterogeneous brittle-ductile deformation at shallow crustal levels under high thermal cond ...[Read More]

Imaggeo On Monday: Computing for a blank globe

Imaggeo On Monday: Computing for a blank globe

A tribute to the computational geosciences. A mix of computer infrastructure, a modern workstation, and a simple globe with coastlines. Found this scene at the back of room at Miraikan – the National Museum of Emerging Science and Innovation in Tokyo, Japan. The computers, screens, and globe are behind a plexi-glass and while not intended as part of an exhibition it almost becomes an art-mee ...[Read More]

Imaggeo On Monday: Mud extrusion, Gobustan, Azerbaijan

In Gobustan, Azerbaïdjan, gases such as methane or carbon dioxide are emitted in the underground. They lower the density of the overlying sediments which are pushed upwards by buoyancy. Fingering instabilities occur, where more mobile and lighter sediments form vents and mud volcanoes with upwards moving material. Many small scale cones are deposited when the conduits reach the surface, depositing ...[Read More]

Imaggeo On Monday: Comb through the mysteries of Comb Ridge, Utah

Scientists have combed through the mysteries offered by this ridge for a long time. This is an aerial image of the linear north-south ridge in South-Eastern Utah. First mapped by modern geoscientists in the late 19th century, the ridge is home to numerous Puebloan cliff dwellings and petroglyphs. It is a National Natural landmark and home to the only fossils of a mammal-sized cynodonts (tritylodon ...[Read More]
