Selenizones

Selenizones are a hypothetical concept in selenology, the study of the Moon. The term refers to regions on the lunar surface that are thought to possess unique characteristics or geological histories, potentially distinguishing them from surrounding areas. While not a formally recognized classification in the same way as maria or highlands, the idea of selenizones suggests that the Moon's surface is not uniformly developed but rather composed of distinct zones with varied origins.

These zones could be defined by a range of factors. For instance, a selenizone might be characterized by a specific type of mineral composition, an unusual density of impact craters, a particular range of surface elevations, or evidence of past volcanic activity. Some researchers have proposed that certain features, such as deep, ancient impact basins or regions with anomalous magnetic fields, could be considered examples of selenizones. The concept also extends to the possibility of zones influenced by unique processes, like enhanced or diminished regolith development, or areas with distinct spectral signatures detected from orbital or ground-based observations.

The study and identification of potential selenizones are ongoing endeavors. As our understanding of lunar geology and its formation processes evolves through missions and analysis, the definition and boundaries of such hypothetical regions may become clearer or be refined. The concept serves as a framework for exploring the complex and diverse nature of the Moon's surface on a more detailed scale than broad classifications typically allow.
