Hot Rocks Meteorite Identification

"The abundant concretions found in the Navajo Sandstone consist of sandstone cemented together by hematite (Fe2O3), and goethite (FeOOH). The iron forming these concretions came from the break down of iron-bearing silicate minerals by weathering to form iron oxide coatings on other grains.

Could this be a sandstone meteorite, Seriously METEORITE

Aug 02, 2019· Sandstone often collects iron as a replacement mineral as more soluble minerals are taken away. It gets heavy. Sometimes this iron forms spherical concretions. Sometimes it just forms "halos" in the sandstone. It is complex chemistry that is really not fully understood (especially by me). But just be satisfied that this is the way it is.

Meteorite FAQ North Carolina Museum of Natural Sciences

Nickel-iron meteorites represent the cores of small planets that formed early in our solar system’s history.As the solid metal cools below 600°C, the metal organizes itself into high-nickel and low-nickel domains, showing an octahedral pattern (Right).

How Utah's Mysterious Moqui Marbles Formed?

The stony spheres are concretions — sandstone balls cemented by a hard shell of iron oxide minerals. Often called moqui marbles, acres of the chocolate-colored rocks are scattered across Utah and Arizona.They tumble from the pale, cream-colored Navajo Sandstone beds, when wind and water wash away the softer rock.

Models of iron oxide concretion formation: field

Iron oxide (e.g. hematite, goethite) sandstone coloration and concretions are significant indicators of the mobility of iron in groundwater and host rock properties such as por-osity and permeability. Iron oxide concretions typically lack any obvious nucleus (Chan et al. 2004, 2005) and appear to form in different ways from simple attractive

Iron-rich sedimentary rocks Wikipedia

Iron-rich sedimentary rocks are sedimentary rocks which contain 15% or more iron.However, most sedimentary rocks contain iron in varying degrees. The majority of these rocks were deposited during specific geologic time periods: The Precambrian (3800 to 570 million years ago), the early Paleozoic (570 to 410 million years ago), and the middle to late Mesozoic (205 to 66 million years ago).

Caliche: Also known as calcrete, hardpan, and duricrust

"Caliche" is a shallow layer of soil or sediment in which the particles have been cemented together by the precipitation of mineral matter in their interstitial spaces. The cement is usually calcium carbonate; however, cements of magnesium carbonate, gypsum, silica, iron oxide, and a combination of these materials are known.

Everything You Need to Know About Sandstone

Aug 14, 2019· Sandstone, simply put, is sand cemented together into rock — this is easy to tell just by looking closely at a specimen. But beyond that simple definition lies an interesting makeup of sediment, matrix, and cement that can (with investigation) reveal a great deal of valuable geologic information.
