Excellent example for the species and locality, a crystallized ball of okenite 1.2 cm in diameter set perfectly in the center of matrix. In great condition.The basalt flows of Columbia County, Oregon, part of the local volcanic sequence, formed from ancient lava episodes featuring extensive gas cavities that now host diverse secondary minerals. Mineral collectors frequently explore these vesicular rock units for rare micro-specimens and crystal assemblages. Within these cavity systems, okenite occurs as delicate, white, fibrous spherical aggregates, developing alongside various zeolites and related silicate minerals through low-temperature hydrothermal alteration processes.
