A hypothetical mineral or geological term, or a playful scientific neologism possibly combining 'griph' (griffin) with the mineral suffix '-ite'.
This appears to be either a nonce word or a manufactured term combining 'griph' (griffin, from Greek) with '-ite' (a common mineralogical suffix naming minerals), not established in standard geological literature.
Minerals get named with the '-ite' suffix all the time—'hematite,' 'magnetite,' 'graphite'—so 'griphite' SOUNDS like it should be a real mineral! This shows how word structure helps us recognize and invent scientific terms.
