Welcome to my profile. I am a science educator. On commons I like to create pictures and diagrams that illustrate science content, mostly but not exclusively geology-related. If you like me to translate any SVG uploads into another language, please ask.

Some files I made:

Pictures of rocks

• 
  A boundstone, a clastic sedimentary rock made of fossils. In this case Jurassic Pelecypoda gryphea shells
• 
  Isoclinal folds and shearing in an orthogneiss
• 
  Large-scale folds in a mountain side (Gasteretal, Switzerland)
• 
  White vesicles (bubbles) in basaltic lava
• 
  Diamond-bearing kimberlite, green pyroxene clasts
• 
  Pyroxenite and peridotite banding: result of fractional crystallisation in the Earth's mantle
• 
  Piece of the Earth's mantle taken to the surface by volcanic activity
• 
  Mylonitic and amphibolitic gneiss, nice porphyroclasts
• 
  Large phenocrysts in a granite. Most likely they form by recrystallisation when the intrusion cools
• 
  Boudinage in a sheared orthogneiss
• 
  Ultrahigh pressure metamorphism turned this gabbro (after being subducted) into an eclogite
• 
  Banded Iron Formation, more than 3 billion years old
• 
  Thin sections of rocks under the microscope

Pictures of fossils

• 
  Fossil fern from the Upper Carboniferous (300 million years old)
• 
  Annularia stellata, another Carboniferous plant fossil
• 
  Fossil ammonite from the Lower Cretaceous (130 million years old)
• 
  More lower Cretaceous ammonites
• 
  Fossil trilobite from the Devonian (360 million years old)
• 
  Claw of the dinosaur Therizinosaurus (70 million years old)
• 
  Grasshopper fossil in an Upper Cretaceous rock

Diagrams
