GeoPicture of the Week: Martian Chronicles


The Astro-geology team working on analyzing the photos from Curiosity Rover is having a busy week. They recently posted this amazing picture and announced their plans for the future. The plan for the weekend is to do a detailed analysis of the outcrop in front of us and then drive away and do some untargeted observations. Sol 1109 includes ChemCam

NASA recently uploaded a strikingly beautiful photograph on their website showing a petrified sand dune on Mars. The image was actually pieced together from several shots taken using Curiosity’s Mast Camera (Mastcam) on August 27th. From end to end, the panorama spans a full 135 degrees of other-worldly awesomeness, with east to the left and southwest to the right.


GeoPicture of the Week: Pangaea with today’s borders


Today’s Spain was close to Greenland, Tibet and Australia were neighbors, and Africa and South America were closely hugging – as can be roughly seen from today’s coastline. This image shows that the Earth is not a static rock – but an active and mobile system.


GeoPicture of the Week: The Chocolate Hills

These brownish hills are actually limestone mounds in Bohol province in the Philippines. They are normally covered by grass, but turn a deep-brown colour during the dry season, looking more and more chocolatey. There are about 1,500 mounds in the Philippines; similar karst mounts exist in Croatia and Slovenia, northern Puerto Rico, and Pinar del Río Province, Cuba – but they’re not covered


GeoPicture of the Week: The First Photo From the Deep Space Climate Observatory Satellite


This week, we’re going for something a little different: this is the first photo from the Deep Space Climate Observatory Satellite, aNOAA Earth observation and space weather satellite launched by SpaceX on a Falcon 9 launch vehicle on February 11, 2015 from Cape Canaveral. This is the Earth in 2015, as seen from outer space. It’s a remake of the famous


GeoPicture of the Week: Mount Fuji from the ISS


Sometimes, astronauts onboard the ISS captures some stunning pictures. Here, we see Mount Fuji, the highest mountain in Japan, an active stratovolcano. Mount Fuji is located at a triple tectonic junction, where the Amurian Plate, the Okhotsk Plate, and the Philippine Sea Plate meet – an extremely volatile geologic area.


Geopicture of the Week: Graben in Iran

In geology, grabens are depressed blocks of land bordered by parallel faults. In German, “graben” means trench or ditch, and that’s a pretty good name for it. Graben are produced from parallel normal faults, where the hanging wall is downthrown and the footwall is upthrown; the faults dip towards the center.

This is how the Moon looks under the microscope!


The Apollo program returned 380.05 kg of lunar rocks and soil, and most of the samples are stored at the Lunar Sample Laboratory Facility. The samples of rocks, breccias, and regolith were polished into thin sections, allowing for optical geologic studies to be performed on them.


GeoPicture of the Week: Fresh Crater on Mars


This jaw-dropping image was taken by High Resolution Imaging Science Experiment (HiRISE) camera aboard NASA’s Mars Reconnaissance Orbiter in the Sirenum Fossae region of Mars. This impact crater appears relatively recent as it has a sharp rim and well-preserved ejecta. The steep inner slopes are carved by gullies and include possible recurring slope lineae on the equator-facing slopes. Fresh craters often have
