These geodes formed through an early magmatic cavity stage followed by low-temperature mineral infilling, commonly yielding richly colored amethyst quartz and distinctive cathedral forms. The state also contains major coal deposits in the Paraná Basin and has produced agate, quartz varieties, and minor wolframite occurrences.
