Monday Geology Picture: The Three Sisters, Blue Mountains, Australia

Monday Geology Picture: The Three Sisters, Blue Mountains, Australia

This week’s Monday Geology Picture was taken during my recent vacation in Australia. One day my husband and I drove outside of Sydney to spend some time exploring the Blue Mountains. One of the tourist attractions that we visited is a lovely rock formation known as The Three Sisters. This rock formation was carved (by erosion) out of ~250 million year old sandstone.

Monday Geology Picture: South African Wind Farm

Monday Geology Picture: South African Wind Farm

South Africa is currently facing a significant shortage of electricity. Recently, there have been regular periods of “load shedding” or planned power outages. Basically, there is often not enough power to go around, so the power is purposely turned off on a rotating schedule. In the neighborhood where I live and work in Cape Town, the power is regularly turned off for two hours a day or sometimes for four or more …

Red Conglomerate Hills Near Oudtshoorn, South Africa

Red Conglomerate Hills Near Oudtshoorn, South Africa

On Monday I shared a picture of a pretty conglomerate that I recently walked across. Today I thought that I would share a few more pictures of this conglomerate formation and also tell you a little more about it. Although in Monday’s picture the conglomerate looks somewhat dull-colored, the conglomerate formation is actually impressively red in color in many places, so much so that hills made of the conglomerate are …

Monday Geology Picture: Conglomerate Near Oudtshoorn, South Africa

A couple of weeks ago I spent part of a weekend staying near Oudtshoorn, South Africa. During a hike, I walked by and, at times, across a beautiful Cretaceous age conglomerate. Here’s one image of the conglomerate, taken when I hiked across it. I’ll share some more pictures in another post.

Monday Geology Picture: Sydney Sandstone Building Stones

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: More Sydney Sandstone

Monday Geology Picture: More Sydney Sandstone

I’m still in Australia at the moment but will be home in a few days. I’m looking forward to writing up a few blog posts about some geological sights in Australia once I’m back home. For now, though, here’s a picture showing another beautiful example of sandstone in the Sydney area. This picture was taken at the Sydney Zoo. The red and orange colors are a result of iron oxidation. …

Monday Geology Picture: Samail Ophiolite Plane View

Monday Geology Picture: Samail Ophiolite Plane View

I’m busy traveling at the moment, so Georneys will continue to be quiet for another couple of weeks. However, I thought that I’d quickly share a picture from my recent flight for this week’s “Monday Geology Picture” post. This picture shows the impressive topography of the Samail Ophiolite, which is located in northern Oman and the United Arab Emirates.  An ophiolite is a section of oceanic crust and mantle that …

Monday Geology Picture: Nimrud Statue at the British Museum

Monday Geology Picture: Nimrud Statue at the British Museum

I was very upset to learn that a few days ago ISIS looted and bulldozed the ancient Assyrian city of Nimrud in Iraq. This war crime is a terrible tragedy, and I hope that not all of the city’s treasures were destroyed. Fortunately, many artefacts from Nimrud are preserved in various museums around the world. In a way, that is bittersweet. I really wish that artefacts from Nimrud could primarily …
