Mount Coot-tha Building Stones

  A few weeks ago, I put up a blog post about a Gold Mine Hike at Mount Coot-tha in Brisbane, Australia.  I wrote that the gold was found in meta-sedimentary rocks, but I didn’t show any good pictures of the rocks. This is because the rocks are highly weathered and also mostly covered with vegetation in the area where the hike is located. This morning I went with my …

Monday Geology Picture: Kangaroo Point Cliffs, Brisbane, Australia

Happy New Year! I’m going to try to keep up with my “Monday Geology Picture” posts in 2019. I did okay with these in 2018, although I missed some weeks here and there when I was very busy with work or family life. To start off a new year of pictures, here is a picture that I took during a recent visit to Brisbane, Australia. This picture shows a place …

Monday Geology Picture: More Airport Geology

I’m traveling again this week (4 weeks of travel in a row!), so today I’m sharing another picture of some “airport geology”. Specifically, this is a picture of some gorgeous decorative stones adorning a column at O.R. Tambo International Airport in Johannesburg, South Africa. I took this picture yesterday when I was passing through the airport.  I particularly like the way the block of rock was split and the set …

Monday Geology Picture: Airport Geology

I travel a lot for my job, and I often find myself traveling through O.R. Tambo International Airport in Johannesburg, South Africa. The terminal buildings contain some lovely decorative stones, which I often admire as I’m navigating my way through the airport. For example, while I was waiting for my luggage today I admired, as I have before, some of the lovely decorative stones that make up part of the …

Monday Geology Picture: Geology Building at the University of Queensland

Earlier this year I visited The University of Queensland in Australia. For this week’s picture, I’m sharing an image of the lovely geology building at the university. The building is made out of gorgeous sandstone blocks… and there’s a dinosaur mural! And, lower down, check out the stones with the fossil carvings! What a great building. I think this is one of the most lovely and delightful geology buildings that …

Monday Geology Picture: Sandstone Building Stone

I’m currently on the east coast of Australia, where local sandstone is commonly used as a building stone. Above is a picture that I took this morning. This picture shows some beautiful building stones on display at the University of Newcastle. The cross-bedding and variable coloration of the sandstone layers is just gorgeous. What a lovely building stone!

Monday Geology Picture: Sydney Sandstone Building Stones

During my recent travels in Australia, I noticed quite a bit of sandstone around Sydney. Therefore, I was not particularly surprised to also see quite a few sandstone building stones around the city. For example, the stones shown in the above picture, which shows part of a bridge in North Sydney. By the way, I’m back home in South Africa now and won’t be travelling for a little while. So, …

Monday Geology Picture(s): Vesicular Basalt Boulder, Mauritius

Continuing with some pictures from my trip to Mauritius back in March, for this week’s “Monday Geology Picture” post I am sharing some pictures of a large boulder of vesicular basalt. This particular boulder is located in the town of Grand Gaube in northern Mauritius and is used as a decorative stone on which a plaque has been mounted. Vesicular basalt is a dark-colored volcanic rock that contains many small holes, …

Monday Geology Picture(s): Fossils in the Floor

My husband and I are travelling in the US at the moment. A little over a week ago we attended an event at the Hynes Convention Center in Boston, and I noticed some interesting fossils in some beautiful building stones on the floor of a hallway connecting the center with an adjacent hotel. I snapped a few pictures of the fossils. Can anyone identify them? Does anyone know where the …

Monday Geology Picture(s): Dendrites in the Tile Shop

First of all, my apologies for missing the “Monday Geology Picture” post last week. I’ve been extremely busy recently with work and also preparing for a much-needed vacation. Actually, I’m on vacation right now, so I’ve set this to auto-post. Never fear, though… when I return in early April I will finish my “Sutherland Sky” series of blog posts. Also, I will be reviving the “Geology Word of the Week”. …

Monday Geology Picture(s): More Coral Building Stones in Zanzibar

Last week I shared some pictures of a coral palace in Zanzibar. This week, I’m sharing a few pictures of modern coral houses in the beachside village of Matemwe, which is located on Zanzibar’s northeastern coast. These days, more and more buildings in Zanzibar are being built out of concrete. This may be a good thing since mining of coral rock may not be the most eco-friendly building practice. However, …

Monday Geology Picture(s): A Coral Palace in Zanzibar

This week I’m continuing with sharing some pictures from my recent vacation in Zanzibar back in June 2013. There is plenty of coral around Zanzibar, and my husband and I noticed that many of Zanzibar’s buildings– both ancient and modern– have been built with coral blocks. As an example, the picture above shows a coral building stone in the Princess Mtoni Ruins, the remains of the childhood home of Princess …

Monday Geology Picture(s): Views from the World’s Tallest Building, Dubai

I’m continuing this week with sharing pictures from my January 2012 trip to visit my friend Karima in the United Arab Emirates. I mostly stayed with Karima and her family in Abu Dhabi, but one day we took a drive over to Dubai. While there, we visited the impressive Burj Khalifa, which is the tallest building in the world. Here on Georneys I often like to post Plane Views or …

Monday Geology Picture(s): A Geologist’s Dream Bathroom, Emirates Palace Hotel, Abu Dhabi

This week I’m continuing with sharing some pictures from my January 2012 trip to visit my friend Karima in Abu Dhabi. During our fancy lunch at the Emirates Palace Hotel, we went to the women’s bathroom, which I immediately referred to as “a geologist’s dream bathroom” because of all of the beautiful decorative stones. Geologists, what types of stones would you put in your dream bathroom?

Decorative Stones of the Sheikh Zayed Grand Mosque, Abu Dhabi – Part II

After putting up my recent blog post Decorative Stones of the Sheikh Zayed Grand Mosque – Part I, I decided to write to the mosque to inquire about the lithologies and origins of the various decorative stones. I promptly received this reply from Michelle Sabti, the Chief Tour Guide for the mosque: Greetings to you Evelyn from the Sheikh Zayed Grand Mosque Center! Thank you for your email, we are …

Decorative Stones of the Sheikh Zayed Grand Mosque, Abu Dhabi – Part I

UPDATE: See Part II for some more information on the decorative stones used in the mosque. After sharing my mangrove kayaking pictures for this week’s “Monday Geology Picture” post, I thought I would share some more pictures from my January 2012 trip to Abu Dhabi, United Arab Emirates. The day after kayaking, my friend Karima and I visited the stunningly beautiful and elaborate Sheikh Zayed Grand Mosque. This impressive mosque …

Monday Geology Picture: A Geologist at the Opera

Several months ago, my husband and I went to the opera. Specifically, we went to see a South African production of “The Phantom of the Opera” at the Artscape Opera House in our home city of Cape Town. I had never visited the Opera House before, and I was impressed with the beautiful building. In this week’s geology picture, I am enthusiastically pointing out some travertine building stone in the …

Monday Geology Picture(s): Building Stones in Rollins Chapel

Last week my husband and I visited my alma mater Dartmouth College in Hanover, New Hampshire. Dartmouth has a beautiful campus, and one of my favorite buildings on the campus is Rollins Chapel. The chapel is a multi-faith spiritual center that is used by students and alumni for a variety of purposes. The chapel is used for spiritual services, quiet reflection, weddings, seminars, speeches, and other events. When I was a …
