peräskerroksisesti

Peräskerroksisesti is a Finnish adverb that translates to "in a layered manner" or "stratigraphically" in English. It is most commonly used in geological contexts to describe how rock layers are deposited or arranged. When referring to geological formations, peräskerroksisesti implies that older rock strata are found beneath younger ones, following the principle of superposition. This principle is fundamental to understanding geological history and dating rock formations.

Beyond geology, the term can be applied metaphorically to describe any situation where things are arranged in distinct, superimposed layers. For example, one might describe a historical account being revealed peräskerroksisesti, meaning that different periods or events are uncovered sequentially, one upon the other. Similarly, in archaeology, artifacts found at different depths in an excavation site can be said to be peräskerroksisesti distributed, indicating their relative ages. The core meaning remains consistent: a sequential, superimposed arrangement.
