Akimotoite is a rare silicate mineral ((Mg,Fe)SiO3) in the ilmenite group of minerals.

And India s government has shown its political savvy by forging an agreement to provide Japan with rare earth minerals a vital component in many manufacturing processes after China chose to use its supplies of rare earths as a diplomatic stick.

From employing its strong trade position to exploiting its near monopoly on the global production of vital resources like rare earth minerals, China has staked out a more domineering role in Asia.

Rare earth mines are found throughout the world.

More recently, after Japanese maritime officials arrested a Chinese fishing boat captain near the disputed Senkaku islands, China responded harshly with arrests of Japanese businessmen, cancelation of student visits, and suspension of exports of rare earth minerals upon which key Japanese industries depend.

There are two series of rare earth metals, the lanthanides and the actinides.

Indeed, rare earth elements are rare only in the sense that they are distributed in small quantities and must be extracted from ores, a time consuming process.

So, in 2000 we wrote Rare Earth. In 2003, we then asked, let's not think about where Earths are in space, but how long has Earth been Earth?

China dominates the global market simply because it has fairly abundant rare earth ores close to the surface.

The raping of the Earth, the pillaging of minerals, the destruction of vaginas none of these were separate anymore from each other or me.

They could not yet produce pure samples of all the rare earth elements, even in the form of their salts, and in some cases they were unable to distinguish between mixtures of two very similar (adjacent) rare earth elements from the nearby pure metals in the Periodic Table.

It's rare that history comes with a man that his fear is set in the hearts of kings all around earth.

The rare earth threat is not confined to Japan, as China accounts for over 90 of the world s production, roughly 120,000 tons.

Carl Sagan and Frank Drake, for instance, could well be considered pluralists while proponents of the Rare Earth hypothesis are modern skeptics.

Other minerals include calcium, uranium, lignite and copper.

Also, the method of separating the rare earth elements by the method of ion exchange had not been invented yet in Moseley's time.

These rocks have low concentrations of large ion lithophile elements (LILE), light rare earth elements (LREE), volatile elements and other highly incompatible elements.

Some of these minerals are essential to human metabolism.

Associated minerals include native iron, schreibersite, troilite and wustite.

Other countries might worry about the health risk to workers in rare earth processing, but that does not appear to be true of China.

Rare earth elements change through time in small quantities (ppm, parts per million), so their proportion can be used for geochronology and dating fossils.

The typical chemical composition of oven dried diatomaceous earth is 80 to 90 silica, with 2 to 4 alumina (attributed mostly to clay minerals) and 0.5 to 2 iron oxide.

This is very rare.

These instances are rare.

Rare earth ores in southern China all except for those in Inner Mongolia contain radioactive substances that pose significant threats to human health and the environment.

Most rare elements on Earth are not needed by life (exceptions being selenium and iodine), while a few common ones (aluminum and titanium) are not used.

Secondly, the raw materials such as magnesium based minerals are abundant.

Political violence has been rare.

These are not rare occurrences.

In the face of aggressive price cutting by Chinese rare earth producers, many mines in the US and elsewhere in the world were shut down over the years.

Many countries are now planning to develop their own or alternative sources of rare earth elements, and to accelerate efforts to develop technologies that are free of them.

Its crystal structure may allow it to replace silicon in silicate minerals.

They are not effective at removing minerals, salts, and dissolved inorganic compounds.

Such biogeochemical cycles are important in geology because they affect many minerals.

If EID s were rare, management through crisis response might be cost effective. But EID s are not rare at all.

Big speculative bubbles are rare events.

Real debt defaults are historically rare.

The smile was rare and constrained.
