Tellides

Tellides is a term that can refer to multiple concepts, but in standard reference materials it is not a widely recognized technical term on its own. The closest established reference is tellurides, minerals that consist of tellurium combined with metals. In mineralogy, tellurides form in hydrothermal systems and magmatic ore deposits and are typically dense, metallic, and opaque. They often occur with other ore minerals and may be processed for tellurium and sometimes for associated noble metals. Notable telluride minerals include calaverite (gold telluride) and sylvanite (silver-gold telluride); other examples include krennerite and hessite.

Tellides as a word sometimes appears in older or nonstandard spellings and may be used in literature as a variant of tellurides. It is not standard in contemporary mineral nomenclature.

In fictional or speculative contexts, Tellides may be used as a proper noun, naming a people, culture, or alien species. In such uses, the details—geography, language, technology, and social structure—are determined by the author and can vary widely from one work to another.

Etymology: Telluride derives from tellurium, named after Earth (tellur-). The form tellide is less common and not widely established in current scientific usage.

Cultural references: When encountered outside mineralogy, Tellides typically refer to a culturally named group or fictional civilization in novels, games, or worldbuilding texts.
