Rhodochrosite with Quartz
specimen number:
2062770
location:
Sunnyside Mine, San Juan Co., Colorado, USA
description: The Sunnyside Mine, located in the San Juan Mountains north of Silverton, Colorado, sits within a complex geological environment shaped by ancient volcanic activity and caldera collapse, producing rich epithermal vein systems filled with precious and base metals along fault zones. Mining operations began in the early 1870s and expanded through multiple phases of deep tunneling, technological milling advancements, and recovery from significant setbacks such as the famous 1978 Lake Emma disaster, ultimately operating as one of the region's most productive and enduring lode mines before closing permanently in the early 1990s.
Classic Colorado specimen with pink opaque rhombohedral crystals of rhodochrosite, one primary cluster 1.8 cm across, set up on crystallized quartz. This is in good condition. The specimen comes with a previous label from the collection of Ray DeMark.
Size: 6.0 x 6.0 x 4.0 cm (small-cabinet)
