The frigid Ural Mountains in Eastern Russian are located at lat. 64°N and lat. 61°N and create a border between Europe and Asia . The Urals are one of the World most ancient mountain ranges being created about 300 million years ago! These incredible mountain forms were created by a continent to continent convergent plate collision, categorizing the Urals as linear folded mountains.
The extreme pressure of this collision can be seen in the large amount of warped metamorphic rock, schist, and gabbro. All still in tact because of there durability against weathering and erosion.

The ancient collision of the supercontinent Pangaea created these peculiarly located mountain ranges miles from any rift valley or subduction zone. Because the age of the Urals there are many diverse geological features and a bounty of precious and semi precious metals and stones.

This aesthetic differentiation in the Urals is caused by weathering and erosion of limestone regions and durability of the metamorphic regions.
Many breathtaking views of dark mafic rock structures from the ancient ocean crust can be seen. There are also many multicolored strata on open cliff faces from years of sedimentary rocks being created.
The pictures in your blog are awesome. The first diagram really helps explain the process. The blog sounds very scientific, not like someone who just learned the content. Moving around the paragraphs might help the flow better. For example placing the Pangea paragraph closer to the beginning.
ReplyDeleteYou have a lot of good pictures which display the forms and processes that you want to explain, but I think that you could explain more in your captions for the pictures. I like that you told how the beautiful forms in your pictures were made, but you could add how the lives of the people that live there are changed and also connect the different ideas better. If you just fixed a few things, overall this is a good blog that can really teach people about how the Ural Mountains came to be.
