USGS Estimates 40 Million Pounds of Potential Uranium ...
The U.S. Geological Survey estimates a mean of 40 million pounds of in-place uranium oxide remaining as potential undiscovered resources in the Southern High Plains region of Texas, New Mexico, and Oklahoma.The uranium occurs in a type of rock formation called "calcrete," which has been well-documented in noted uranium-producing countries like Australia and Namibia.

Uranium ore - Wikipedia
Uranium ore deposits are economically recoverable concentrations of uranium within the Earth's crust.Uranium is one of the more common elements in the Earth's crust, being 40 times more common than silver and 500 times more common than gold. It can be found almost everywhere in rock, soil, rivers, and oceans. The challenge for commercial uranium extraction is to find those areas where the ...

Uranium Geology of the West
Roll-fronts are the predominant uranium deposit in the RMIBUP and the CPUP, and the only type found in the GCUP. The uranium is typically deposited as uranium oxides and, to a lesser extent, uranium silicates. Uranium concentrations range from 0.04 to 0.25 percent; the deposits generally range in size from 0.5 to 20 million pounds.

Element reactions. The most important uranium ore is uranite, usually called pitchblende. Uranite's formula is roughly UO 2. Uranium is surprisingly common and is more plentiful than mercury, silver, or cadmium in the earth's crust, and is about as abundant as molybdenum or arsenic. Much of the earth's internal heat is thought to be ...

The Energy problem — Tiki the Penguin
Types of energy. Potential energy is stored in some sort of solid body and has the potential to do work. There are four types: Chemical: energy stored in things like the food you eat, fossil fuels and explosives Elastic: energy stored in a stretched elastic band or spring, for example Gravitational: the energy a body has because it's near to another large body, like a planet.

Helium in Radioactive Rocks | Answers in Genesis
During the radioactive decay of uranium and thorium contained in rocks, lots of helium is produced. Because helium is the second lightest element and a noble gas—meaning it does not combine with other atoms—it readily diffuses (leaks) out and eventually escapes into the atmosphere.

Uranium radiohalos. It is known that the halos are formed by radioactive uranium inside the zircons. 1, 2 The radioactivity damages the biotite and changes its colour (figure 2). That's why the spherical halos are called 'radiohalos' (short for radioactive halos), and their centres are called 'radiocentres'.

The Navajo Nation and Uranium Mining
While the Navajo were struggling economically during the nuclear age, uranium was discovered on their reservation. Uneducated about the environmental and health risks from mining uranium, many Navajo men were thankful to have found work so close to home ([Brugge, 2000]).This was the beginning of hardships that were previously unknown to the Navajo people.

Thorium is mined in conjunction with uranium, so much that estimates of reserves for these elements are made based off of uranium content. Thorium is typically found in the minerals thorite, thorianite and monazite however monazite is the only mineral from which Thorium is currently mined. These monazite deposits are found in placer deposits.
