The Colorful World of Geology
Geology is a scientific discipline which investigates the structures, composition and substance of the Earth’s crust. Geologists frequently deal with the current physical characteristics, composition, and most importantly the past formational story of the rock. May sound boring, but we assure you: It isn’t! The world of geology and the history of the earth have many colorful sides, and OMV geologists capture many of those features on film.
If you cut the Earth in half, you could see see the internal composition, namely the inner core in the center which is surrounded by an outer core, then the mantle, and finally the thin solid crust which floats on the outside where we live. It took billions of years of various processes to achieve the current form, and this process is far from complete. Through the impact of volcanoes, earthquakes, and even rain, the Earth’s crust is continuously changing and renewing itself every single day, all around the world.
In places where chemical elements, such as iron or sulfur, come loose from existing rock or have replaced other elements, the rock changes color. In an interplay with erosion, this can result in intense color variations that you would never expect in nature. Astrid Metz, Geologist at OMV Exploration & Production GmbH
About Colors and Shapes
Rocks are composed of various types of minerals, and different types of chemical and physical reactions can lead to different types of minerals. These minerals can have many different compositions, physical characteristics, and colors. The colors alone can tell a very interesting story. For example, red rocks can be formed during very dry periods or in dry regions which can imply a desert. Yellow is indicative of sulfur and can point toward a volcanic origin. The formation of these minerals and rocks and their associated colors are only the beginning of the story. The impact of water, wind, and ice sometimes can erode rocks into very bizarre shapes.
In their daily work, our geologists work with the Earth’s crust around the clock. That’s quite a lot of time looking at rocks, one might think. However, for OMV geologists their work is not just a job, it’s a passion and a calling that does not become less fascinating even when researching it in their free time. “Rocks fascinate us in all colors, shapes, and no matter where we find them. They tell us a great deal about how they were formed,” says Astrid Metz.
Over the years the following photographs were captured by our geologists on their journeys outside the office. Now we know why they love rocks and we hope to share that love with you.
