👉 Spodogenous is a concept in geology that refers to an area where the rock layers are very similar in composition, texture, and thickness. This type of geology occurs when two or more different rock types have similar chemical compositions and physical properties, making it difficult for them to be distinguished based on their specific characteristics. In other words, spodogenous rocks are characterized by having a smooth surface with no sharp edges, often resembling sandstone. They tend to be thin and relatively uniform in thickness
