Kladistiseen

Kladistiseen is a Finnish term used in geology to describe things related to clastic rocks and processes. It functions as an inflected form of the adjective kladistinen (or, more commonly, klastinen), which denotes rocks or sediments composed of fragments derived from pre-existing rocks that have been weathered, transported, deposited, and lithified. The concept corresponds to the English word “clastic.”

Etymology and variants: The word derives from the Greek klastos meaning "broken," through Latin clasticus, and has been adopted into Finnish as klastinen. In contemporary Finnish, the standard spelling is klastinen; kladistinen appears mainly in older texts or as a variant spelling. The form kladistiseen represents the inflected form used in certain syntactic contexts when modifying a noun.

Usage: In geological literature, klastinen terms are used to classify and describe sedimentary rocks and their textures and origins. Clastic rocks include materials such as sandstone, shale, and conglomerate, which are built up from fragments of other rocks. Phrases in Finnish may include klastisen, klastisesta, or klastiseen depending on case and grammatical role, with kladistiseen appearing in contexts that call for that specific inflection.

Context: The term is specialized vocabulary within geology and sedimentology. While both klastinen and kladistinen may be encountered, klastinen is the more common modern form, with kladistinen largely limited to certain texts or historical usage.
