Fact & Fault Model

FINE WHITE MARBLE | Formed from limestone, this high pressure, low heat alteration leads to a large crystalline rock. Heavily mined for architecture, marble is also used for buildings and furniture GREAT FOR GEOLOGY CLASSROOMS | While denser than limestone, marble is still effervesce in acid, making this metamorphic rock useful in identification activities GEOLOGIST SELECTED | Each specimen is selected and hand processed by an actual geologist, ensuring each sample exhibits defining features LOCALLY PROCESSED | Our rock and mineral samples are sourced from a variety of locations around the world and are processed in Victor, NY INDIVIDUALLY PACKAGED & LABELED | Each specimen sample is packaged in a transparent bag, and is labeled & barcoded for easy identification
