Description

Sincere apologies to those that may look forward to my posting daily, I should be back on track now. Came across this out cropping of the material from which Moki Marbles come from. These abundant concretions found in the Navajo Sandstone consist of sandstone cemented together by Hematite (Fe2O3), and Geothite (FeOOH). The iron forming these concretions came from the break down of iron-bearing silicate materials by weathering to form iron oxide coatings on other grains. During later diagenesis of the Navajo Sandstone while deeply buried, reducing fluids, likely hydrocarbons, dissolved these coatings. When the reducing fluids containing dissolved iron mixed with oxidizing groundwater, they and the dissolved iron were oxidized. This caused the iron to precipitate out as hematite and goethite to form the innumerable concretions found in the Navajo Sandstone. Some info. from Wikipedia Thanks for all the comments and favs on part I. The kind support makes sharing all the sweeter.

Thanks for the info. I think this explains the cow pie-looking formations I found over in Utah at the edge of one of the Horse Canyos. They did look like they had at least some Fe component and hydrocarbons. Interesting stuff, in small doses with lots of pictures. :D
