Abstract photography can produce very dramatic images. It relies on our more primal sense of form, color, and curves than it does on detail. The problem is that most photographers tend to think in terms of detail when evaluating photographic opportunities.
Today, matching belts of sedimentary rock, known as the Old Red Sandstone, are found in Scandinavia, the United Kingdom, and eastern North America.
Some of the oldest known rock formations, formed over 3,700 million years ago, include banded iron layers. Banded layers rich in iron were mostly deposited between 2,400 and 1,900 mya. Phanerozoic ironstones generally have a different genesis.
