Monday Geology Picture: Cape Town Fire Smoke

Monday Geology Picture: Cape Town Fire Smoke

Currently, forest fires are raging here in Cape Town, South Africa. You can see some images of the fires here and here and here. I live and work relatively far away from the fires. However, from my office today I could see smoke from the fires in the distance. I hope that the fires are put out soon since they threaten much of Cape Town’s beautiful forest as well as …

Monday Geology Picture: Pink Pan

Monday Geology Picture: Pink Pan

Apologies for the recent gap in my blogging. I’ve been busy travelling for work, and our home internet connection was not working for a couple of weeks. We’ve also been suffering from regular power outages here in South Africa. Anyway, to make up for my recent quietness, I’m sharing a spectacular picture for this week’s “Monday Geology Picture” post. This picture was taken close to the border between South Africa …

Monday Geology Picture: Kolmanskop from Above

However, I have another “Geology Word of the Week” post coming up soon, so stay tuned! Today I want to share another view of the abandoned diamond mining town of Kolmanskop. I’m currently in Namibia for business, and I flew over Kolmanksop earlier today and managed to snap a few …

Monday Geology Picture: One More Egyptian Artefact from the British Museum

Monday Geology Picture: One More Egyptian Artefact from the British Museum

Over the past few weeks, I’ve been sharing pictures of ancient Egyptian artefacts from the British Museum for my “Monday Geology Picture” posts. Here’s one last picture from the British Museum: a rock slab engraved with ancient Egyptian figures and writing. I didn’t take a picture of the informational sign, so let me know if you recognize the artefact. I think that this picture shows part of a larger artefact. Whatever the artefact, …

Jasper is most often red in color but can also be yellow, brown, green, or gray.   For this week’s Geology Word of the Week post, we’re going to learn a little about silica, aka silicon dioxide or SiO2. More specifically, we’re going to learn about silica minerals. Silicon and oxygen are the two most common elements in the Earth’s crust and are found in many, …

Monday Geology Picture: A Granodiorite Horus

Monday Geology Picture: A Granodiorite Horus

For this week’s “Monday Geology Picture” I thought that I would share a couple more pictures that I took during my recent visit to The British Museum. When I was in one of the exhibits with ancient Egyptian artefacts, I was struck by a beautiful dark-colored Horus statue with a light-colored vein running through it. According to the museum sign, the statue was carved out of granodiorite. The vein is probably …

Geology Word of the Week: I is for Ice

Geology Word of the Week: I is for Ice

def. Ice: Water (H2O) in a solid state. When naturally occurring, ice is considered a mineral. There are many forms of ice: lake ice, river ice, sea ice, snow, glaciers, ice caps, ice sheets, and frozen ground (such as permafrost).   If you ask a geologist what he or she considers to be Earth’s most important mineral, you will probably hear many different answers, depending on the person. Some might …

This week’s picture shows two beautiful ancient Egyptian stone jars. The jar on the left is made out of limestone breccia while the jar on the right is made out of andesite porphyry. Here’s the museum sign about the two jars:

Geology Word of the Week: H is for Hand Lens

Geology Word of the Week: H is for Hand Lens

I’ve decided to bring back the long-lost “Geology Word of the Week” posts in 2015. For those of you who don’t know, for a few years I regularly posted about a geological word every week. These posts included a brief definition (written by me) of the word and then some additional information and pictures. However, starting in 2012 I stopped posting these words regularly. I was quite busy in 2012 because …
