Summary
[edit]DescriptionCarbonatite (Dreamers Hope Carbonatite, Early Cambrian, ~524 Ma; Road Gulch, Wet Mountains, Colorado, USA).jpg |
English: Dreamer’s Hope Carbonatite (cut surface; field of view: 5.3 cm across).
This rock is from a carbonatite dike that is peripheral to the McClure Mountain-Iron Mountain Alkaline Complex in Colorado, USA. The northwestern side of the complex has a halo of radiating carbonatite dikes - the Dreamer’s Hope is one of these radiating dikes. I’m not sure of the mineral content of this rock, but there appears to be at least two carbonate minerals (the cream-colored areas & the reddish-brown areas). The reddish-brown material appears to be ferruginous calcite. The creamish-colored material may be dolomitic. Sphalerite and galena have been reported in rocks from here. The sample does have galena on the flip side. Age: late Early Cambrian, ~524 m.y. Locality: Road Gulch, northern Wet Mountains, southwestern Fremont County, south-central Colorado, USA. |
