A type of mineral or mineral variety, though the term is quite rare and specific to specialized geological contexts.
The suffix '-ite' is standard in mineralogy for naming minerals (from Greek 'lithos,' stone). The 'bye-' prefix or root is obscure in this context, possibly referencing location or a scientist's name.
Mineral names often honor discoverers, so 'byerite' might be a lost tribute to someone whose contribution to geology has been forgotten, making it a linguistic ghost of scientific history.
