Everest Summit Limestone

Most people I talk to about geology are aware that the Himalaya formed by the buckling and uplift of crust caught up in the India-Asia collision. But, I do see eyebrows raised when I tell them that the summits of some of the highest peaks are made up of marine sedimentary rocks. The summit of Mount Everest is a fossil bearing limestone of Ordovician age. What happened to these sediments as

Ugly Map Colors

Too bad modern geology is taking a step backward with their geologic mapping colors.  I have yet to see an official standard calling out the new colors. You used to get a choice at, but no more.  Are they using a traditional system for the sake of tradition under the guise of priority.  This is almost as bad as illustrating ammonoids upside down of their assumed life position

Ok, I am exaggerating. Last week I hosted the @Geoscitweeps account and tweeted 8 stories about Indian geology. This is an earth sciences focused rotating twitter account curated by science writer Sandhya Ramesh (@sandygrains).  Geologists from all over the world have been volunteering to host the account for a week and tweet about their work. I volunteered for the week beginning October 16

The Serpents Of Nagling- Granite Intrusions Into Greater Himalayan Sequence Metamorphics

Over chai, elders told us about large serpents invading their village. A curse, they said. Only the correct prayers and purification rituals saved them, forcing the serpents to retreat deep into the forest. Some serpents remain trapped in the rock faces near the village, which was renamed Nagling (Nag means cobra..or more generically serpent). The picture below are the entombed serpents

High Water Across the West: The Humboldt River in Carlin Canyon — With the Carlin Canyon Unconformity! 

Looking for Detachment [2017-05-23 18:00:00]  recommend  recommend this post  (87 visits) info
Well, there we have it: the Carlin Canyon unconformity with the Humboldt River running nearly bankfull on April 11th of this year. Looking downstream, back toward the tunnels, we're actually still looking at the unconformity, but it's cropping out poorly on the slope below the tilted limestone beds of the Pennsylvanian-Permian Strathearn Formation. I went ahead and cropped the best photo

High levels of radioactive material migrating down into soil around Fukushima

High levels of radioactive cesium remain in the soil near the Fukushima Daiichi nuclear power plant and these radionuclides have migrated at least 5 centimeters down into the ground at several areas since the nuclear accident five years ago, according to preliminary results of a massive sampling project being presented at the JpGU-AGU joint meeting in Chiba,

Using Google Earth for Earth Science Education

I am creating a series of Google Earth labs to use with my middle school Earth Science textbook Earth Science: God’s World, Our Home. For the most part, these labs could be used with other textbooks as well, though I do occasionally refer to figures or pages in my textbook. At this stage, I would love […]

My GigaPan expedition has landed at Rathlin Island, north of Northern Ireland, within view of Scotland, for a few days. The beach on Church Bay is cobble-covered and steep, and the cobbles reflect the island’s geology, with some anthropogenic components thrown in for flavor: Link GigaPan by Callan Bentley But I was struck by these two cobbles, each showing a pervasively shattered breccia of chert: To me, that is not | Impressum
