The geologist carefully examined the calcspar sample from the cave wall.

Field geologists collected several calcsilicates from the outcrop to analyze their formation conditions.

At the coastal outcrop, researchers collected several calcschists to analyze their carbonate content and deformation features.

The geologist sampled a calcsilicate from the contact metamorphic zone to analyze its mineral composition.

The outcrop of calcschist along the river revealed folded layers and recrystallized minerals that told a complex metamorphic history.
