What makes you think that? There is a massive REE deposit that sits next to the oil sands and under the oil sands, how would it be extracted without hacking down forests and raising toxic dust? Mine the oil first then go after the REEs?



You've heard of the mesosphere haven't you?

The mesosphere (/ˈmɛsoʊsfɪər/; from Greek mesos "middle" and sphaira "ball") is the layer of the Earth's atmosphere that is directly above the stratosphere and directly below the thermosphere. In the mesosphere temperature decreases with increasing height. The upper boundary of the mesosphere is the mesopause, which can be the coldest naturally occurring place on Earth with temperatures below 130 K (−226 °F; −143 °C). The exact upper and lower boundaries of the mesosphere vary with latitude and with season, but the lower boundary of the mesosphere is usually located at heights of about 50 kilometres (164,040 ft; 31 mi) above the Earth's surface and the mesopause is usually at heights near 100 kilometres (62 mi), except at middle and high latitudes in summer where it descends to heights of about 85 kilometres (53 mi).

I think you're missing the point. If there's no greenhouse effect then when we're not facing the sun we should be doing the same as the moon does--dropping hundreds of degrees in temperature come nightfall.

Any association with oil sands deposits is coincidental, the formation process is completely different and the mining of REEs still only requires removing a fraction of the covering forest and overburden compared to oil sands development.

One ton of thorium will power a 1,000 MWe nuclear power plant for a year, it would take about 4 million tons of coal to do the same.

The mining and material needed for power generation is on a completely different scale between thorium and coal and oil sands.

Coincidence? There is no correlation between shales and oil? Did you know those non-correlating shales are the cause of heavy metal toxins in the Greenwater and Athabasca rivers that are blamed on oil sands?

That's funny, the last time I looked this was another post about cartoon character breasts.

Principle REEs deposits result as a weathering of igneous rocks, they aren't the result of biological material undergoing transformation into petrochemicals as a result of heat and pressure working on sedimentary deposits at depth.

The Geology of Rare Earth Elements

Rare Earth Element Concentrations

The principal concentrations of rare earth elements are associated with uncommon varieties of igneous rocks, namely alkaline rocks and carbonatites. Potentially useful concentrations of REE-bearing minerals are also found in placer deposits, residual deposits formed from deep weathering of igneous rocks, pegmatites, iron-oxide copper-gold deposits, and marine phosphates.

I'll take that as a yes.

Wow you just described shales but left out the organic compounds, the sedimentary process and the environment they are formed in. You can't pick and choose.

If he doesn't pick and choose his data he would know all the AWG claims are BS.

Shales are sedimentary rocks, REEs are associated with igneous rocks.

Alkaline igneous rocks form from cooling of magmas derived by small degrees of partial melting of rocks in the Earth's mantle. The formation of alkaline rocks is complex and not fully understood but can be thought of as a geologic process that extracts and concentrates those elements that do not fit into the structure of the common rock-forming minerals.

The resulting alkaline magmas are rare and unusually enriched in elements such as zirconium, niobium, strontium, barium, lithium, and the rare earth elements. When these magmas ascend into the Earth's crust, their chemical composition undergoes further changes in response to variations in pressure, temperature, and composition of surrounding rocks. The result is an astonishing diversity of rock types that are variably enriched in economic elements, including the rare earth elements. The mineral deposits associated with these rocks are likewise quite diverse and awkward to classify, in that the distinctive features of these deposits and their rarity can result in classifications that have only one or a few known examples.

Rare earths are concentrated and deposited as part of igneous rock formation, not sedimentary.

REEs are deposited as part of igneous rock formation, not sedimentary, the two are very different.

I'm not sure why Petros is trying to connect them with the oil sands, but it has nothing to do with reality.

As opposed to claiming that rare earths are formed by sedimentary deposit as with shales and sands.

What's the point in discussion if you don't understand basic geology.

Who said they were formed from sedimentary? What is called when rock is weathered, heated and compressed back into rock? What type of sedimentary rock is made of mainly weathered and then cemented igneous rock? What are clastics?

REEs are found commonly with:

Oil sand and oil shales are formed by the deposit of eroded materials in rivers, lakes and oceans over a period of time and can include biological material that over long periods of time turns into petro-chemicals. A magma body may intrude into a shale or tar sands deposit, but the two process are independent. REEs are often found in places with few fossil fuel deposits.

The two are only coincidentally connected.

Shale - Wikipedia, the free encyclopedia

'Black shales' are dark, as a result of being especially rich in unoxidized carbon. Common in some Paleozoic and Mesozoic strata, black shales were deposited in anoxic, reducing environments, such as in stagnant water columns. Some black shales contain abundant heavy metals such as molybdenum, uranium, vanadium, and zinc.[6][7][8] The enriched values are of controversial origin, having been alternatively attributed to input from hydrothermal fluids during or after sedimentation or to slow accumulation from sea water over long periods of sedimentation.[7][9][10]
