Details: The Eisco Raw Coarse Marble specimen is a 3-inch hand sample of metamorphic rock ideal for classroom study and hands-on learning. Formed from limestone under high pressure and low heat, marble has a massive crystalline texture that helps illustrate the effects of metamorphism in geology lessons.
This specimen is excellent for identification activities, as it retains the ability to effervesce in dilute acid, distinguishing it from non-carbonate rocks. Each piece is individually labeled and barcoded, and comes packaged in a clear storage bag. Hand-processed in Victor, NY, this sample supports NGSS-aligned instruction on rock transformation and mineral properties.

Package Dimensions: 6.5 x 4.5 x 2.0 inches
