Kmetasomatism

Kmetasomatism is a theoretical concept exploring the potential for mineral transformation and deposition within a geological context that is influenced by extraterrestrial factors. The term itself suggests a combination of "kmeta" potentially referring to a foundational or external element, and "soma" or "soma" meaning body or substance, with "ism" indicating a doctrine or practice. In essence, it proposes that processes originating beyond Earth, such as impacts from celestial bodies or the deposition of interstellar dust, could directly trigger or significantly alter geological formations and mineral compositions.

This concept is largely speculative and lacks widespread acceptance within mainstream geology, which typically focuses on terrestrial processes like plate tectonics, volcanism, and erosion. However, proponents might point to evidence of extraterrestrial material found in impact craters or certain rare mineral formations as potential, albeit indirect, support for the idea. The core premise is that not all geological changes can be explained solely by Earth-bound mechanisms, and that external cosmic influences might play a more direct and active role in shaping the planet's mineralogy and lithology than currently acknowledged. Further research would be needed to establish any verifiable scientific basis for kmetasomatism.
