Product Overview
Shale is formed from the cementation and lithification of very small grains of rock, commonly mud or clay. The small clast size indicates that though the grains had been heavily eroded, the rock formed in a low energy environment. Shale is useful in sedimentary rock identification exercises due to its recognizable fissile habit.
While each specimen will vary slightly in shape, size and color, it will measure approximately 1" in length. Pack of 12. Each set is individually packaged, labeled & barcoded for easy identification and storage.
