The geologist carefully labeled the specimen schorl before placing it in the museum case.

During the field expedition, the geologist collected several schorls from the exposed pegmatite vein for laboratory analysis.

The schorly vein running through the granite gave the rock a distinctive black streak.

The schorlaceous veins running through the granite made the countertop look like a slice of night sky.

The geologist noted the schorlous veins cutting through the granite.

Several schorlomites were identified in the rock sample, suggesting a complex mineral history.

During the field survey, the team discovered a pocket containing schorlomite embedded in the metamorphic host rock.

The geologist carefully examined a glossy schorlite crystal embedded in the pegmatite.

The schorlitic veins gave the granite an unmistakable black streak that fascinated the geologists.
