Description

The sample is a tubestone stromatolite of the Neoproterozoic Noonday Formation, a post-glacial cap carbonate, from the Queen of Sheba mine in Death Valley. Notably, the inner tube, which appears here as the more resistant portion of the rock and likely rich in silica, co-exists with galena and other sulfide minerals, hence it was mined for lead and zinc at one time.

The image is upside-down.

The exact location and a history of the Queen of Sheba mine can be found at the following website: www.nps.gov/history/history/online_books/deva/section3a12.htm Will open in a new tab or window
Sample provided by Dr. Jay Kaufman of the University of Maryland.
