What is Siltstone?

Siltstone is a clastic sedimentary rock composed of fine-grained particles, primarily silt-sized. It belongs to the mudrock category, characterized by a relatively low amount of clay minerals and lacking the ability to split into thin layers like shale. It forms in various environments, including riverbeds, lakes, and oceans.
