Ochre from Zimbabwe

ochreA reader in Zimbabwe sent in a photo of his sedimentary rock—a lovely specimen of ironstone displaying the arresting colors of limonite and hematite. As a bonus, he includes a photo of an ancient rock-art site that uses these same minerals as pigments. Be sure to click on the thumbnail images for the full-sized images.

Why not submit one of your own favorite sedimentary rocks?
