Over those millions of years the top of that granite body weathered and some of that phosphate uranium and copper was released.
Uranium minerals in granite.
Redistribution by circulating meteoric waters might have taken place.
There may be found cubic crystals of uraninite black crusts of pitchblende and plates of uranium phosphate minerals such as torbernite cu uo2 po4 2 8 12h2o.
It is surprisingly easy.
Uranium is an incompatible element within magmas and as such it tends to become accumulated within highly fractionated and evolved granite melts particularly alkaline examples.
Uranophane zippeite and becquerelite are the most abundant uranium minerals.
In this study the long term mobility of natural uranium in the kaeri underground research tunnel kurt site was investigated using sequential chemical extraction and isotopic analyses of natural uranium in granite.
Uranium also does not usually form very insoluble mineral species which is a further factor in the wide variety of geological conditions and places in which uranium mineralization may accumulate.
The origin of these secondary minerals is mainly related to alteration of primary minerals by the action of oxidizing fluids mobilization of uranium and then redeposition in other forms.
It was found that uranium vi would be leached out due to preferential leaching of 234u relative 238u and concentrated by an uraniferous enrichment process through long term.
This magma body was laced with some very interesting minerals including copper phosphate and uranium.
Is it possible to unlock this energy from the rock.
This huge pool of magma cooled crystallised and formed a body of granite.
