Native copper in calcite crystals (late Mesoproterozoic mineralization age, 1.05-1.06 Ga; Quincy Mine, Hancock, Keweenaw Peninsula, Upper Peninsula of Michigan, USA) Native copper (Cu) in calcite crystals on copper from the Precambrian of northern Michigan, USA. The bedrock in northern Michigan's Keweenaw Peninsula area with Earth's highest concentration of elemental copper (Cu) in its native state. The copper has been extensively mined, but only one active mine remains (all the easily exploited copper is now mined out). Copper usually occurs in various late Mesoproterozoic-aged basaltic rocks and conglomerates. A beautiful and rare occurrence for native copper in northern Michigan is WITHIN other crystals. The above photo shows transparent to translucent pink calcite crystals having metallic inclusions of native copper. Stratigraphy & age: derived from the upper Portage Lake Volcanic Series, upper Mesoproterozoic (1.093 Ga); copper & calcite mineralization age is late Mesoproterozoic (1.05 to 1.06 Ga). Locality: Quincy Mine, city of Hancock, north of Portage Lake, Keweenaw Peninsula, Houghton County, northwestern Upper Peninsula of Michigan, USA. This stunning mineral specimen from Michigan features native copper crystals nestled in a matrix of pink calcite. The copper crystals are beautifully formed and show off their unique texture and color. The pink calcite adds a lovely contrast to the piece and highlights the natural beauty of the specimen. This high-grade mineral piece would make a valuable addition to any collection of rocks, fossils, and minerals. Enjoy!
