Hopefully some time during the next week I will publish an article about sedimentary rocks. It is a sequel to my post about igneous rocks. I started to collect pictures and made a collage that contains examples of common sedimentary rocks. Here it is as a teaser to the longer post.
Examples of common sedimentary rocks: Cambrian clay from Estonia; fossiliferous Ordovician limestone from Estonia; Devonian Old Red Sandstone from Scotland; rock salt (sylvine) from The Ural Mountains, Russia; red variety of chalcedony (carnelian) from Kazakhstan, bituminous coal from the Donets Basin, Ukraine; sandstone with abundant phosphatic brachiopod shells (phosphorite) from Estonia; conglomerate from Switzerland; and aluminum ore bauxite.
