Usage: mineralogy; geology

Examples

• Gummite is commonly observed in the weathered zones of uranium deposits.
• The bright orange gummite coating indicated the presence of uranium ore nearby.
• Geologists identified gummite as a key indicator mineral during the exploration survey.
• Gummite forms when primary uranium minerals are exposed to oxidizing conditions.
• The specimen contained veins of gummite mixed with other secondary minerals.
