rare earth minerals

[hmmm]

all
i have an assay of some clay and it has small amounts of rare earths.
does any one know anything about rare earths
here are the test results.
Ce 37.3 ppm
Dy 4.82 ppm
Er 2.96 ppm
Eu 1.29 ppm
Gd 5.07 ppm
Ho 1.05 ppm
La 17.9 ppm
Lu .54 ppm
Nb 5.8 ppm
Pr 4.78 ppm
Sm 4.71 ppm
Tb 0.79 ppm
Tm 0.50 ppm
Y 31.1 ppm
Yb 3.49 ppm

Most rare earth mines have other elements that are more plentiful, and the rare earth element recovery are a by product of processing for the other major element. There was a large strike for rare earths south west of Omaha Nebraska this summer - you never know where you will find ore.

California and Colorado are 2 other states I know that have mining areas that have processed it.

It looks like you have a lot of the minerals listed here

hmmm,

REE's have a brought spectrum of uses, from electronics, to hybrid vehicles.

moller's post is correct in the fact Quantum RE minerals, used a 1980s mineral assessment from UNL Nat Res, to further drill for REE deposits.

niobium is used in alloying other metals, increasing tensile strength. It is also used in creation of superconductive materials.

In the area in question, known as the Elk Creek Formation, (Niobium, Neodynium) have been assayed in quantities, similar to those assays in the current leader "China".

Generally "soil" is not the parent material. The "lode" so to speak in the area in question is material at depths of 600' to 1200' below surface. In a layer from the late Ordovician era, when much of the continent was under water.

very interesting, thanks.
the hard pann comes from this dike, i theorize the dike has been working from volcanics and has been slowly depositing this mound of hard pann for millions of years. i assume this volcanic rock has come from deep deaths. do you think i should test it for rare earths.
