Simptomite is a fictional mineral commonly referenced in speculative geology and worldbuilding. Descriptions present simptomite as a rare aluminosilicate with distinctive optical and magnetic properties, valuable in narrative contexts for clues about geological history. The term was coined to reflect its role as a diagnostic marker in imagined rock sequences and to evoke the notion of visible symptoms in a geologic record.
