El Indio Mine, Coquimbo, Chille, Rodalquilarite, Alunite, Walfordite, etc.

The El Indio Mine is a series of epithermal, copper and precious metals orebodies in the Andes mountains east of La Serena, Chile. It was a gold and copper mine with a high level of tellurium in some areas. Well known geologist, Phillip Walford collected these specimens and has asked me to distribute specimens into the mineral community. Here are a number of fine examples.

  • There are quite a few balls of bladed, green rodalquilarite crystals in this alunite crystal-lined vug in dacite. Some of the rodalquilarite balls are abraded but many are pristine, crystals speckled with small white spheres of mansfieldite. There are also lots of mansfieldite balls scattered over the alunite crystals. Excellent example!

  • This is interesting. The vug on the top of this brecciated matrix is lined with alunite crystals, sopme just light beige while others are strongly zoned with an outer, presumably iron-rich, alunite zone. In the vug, similarly coloured clusters of jarosite crystals largely cover some of the alunite crystals. Interesting!

  • A vug in the side of this quartz matrix has a vug containing textbook, beautiful, light blue-grey scorodite crystals, associated with alunite. Nice crystals!

  • There are a number of cavities lined wit halunite crystals in this matrix. In one of them is a ball that is a pseudomorph of emmonsite after rodalquilarite. As well, there are lots of white balls of mansfieldite scattered about. Interesting and unusual!

  • This is a large cabinet specimen of alunite crystals with loads of light bluish scorodite crystals mostly on one side. The alunite crystals are curved rhombs which resemble dolomite crystals. The scorodite crystals are sharp clusters of micro crystals to a mm across. Interesting!

  • The front of this specimen is covered with beige crystals of alunite which, in turn are generously sprinkled with balls and crystals of very light blue scorodite crystals. Stands perfectly for display.
