What is that clear matter in the first pallasite?

That is pure olivine crystal, as a gem, it is known as Peridot.
There are different shades, ranging from clear, to yellow to green

Addendum: Peridot is mined in many places of the world, but especially Arizona and New Mexico. The difference here is age. While terrestrial deposits of Peridot have ages in the hundreds of millions of years, Pallasite Peridot is over 4 billion years old.

Here is a USGS site that describes earth mining of Peridot: USGS - Peridot Mining

Thank you. As a follow up, I might do a side piece on the 39 known pallasites, with a short blurb on the particulars of each.
There are many holes in my collection for Pallasites, as some are just hard to obtain, unless you have deep pockets.

oooh, now I want one.

The clear pallasite that is..

So what about the solid inner most core? Do we have those as meteorites?

Yeah, that'll work. Roll it up and smoke it in your Scooby Van.

Nice post charlyv,

s and f for you,

The origins of extraterrestrial olivine is a much debated subject, from the exploded planet idea to the fact that we know olivine is created in the atmospheres of oxygen and magnesium rich stars, and condenses out of the plasma when the star goes nova.

But, iron "splashed" onto olivine, to me clearly shows the presence of molten core of whatever body produced those meteors.

That is a good question. Immediately surrounding that solid core, is liquid Iron and trace Nickel. These would be the octahedrites - Samples being Gibeon, Sikhote Alin, Odessa and Nantan. The solid Irons.

Meteors and Asteroids of that class have produced some pretty big holes in this planet, as they hardly ever burn completely up and lose cosmic velocity. One of the most recent, is Canyon Diablo, which made the Barringer meteor crater near Flagstaff, AZ. Irons were most likely responsible for craters like Sudbury and Vredfort (huge) and perhaps Manicouagan. However, evidence has it that Chixilub was a chondrite.

What is at the exact center of the Earth is probably something very exotic. We do not really know... A combination of Iron, Lead,Gold,Platinum and Uranium with Carbon (Diamonds) intermixed in that matrix? Jury out on that, as we do not know what those pressures and heat can really produce , given the heavier materials that would most likely seek the center of the Earth. That material is so rare, we may have not found a sample of it yet.

Interesting stuff.. thanks for the reply.

Now only if a meteor made of gold, platinum and diamonds fell in my back yard.

I would certainly wish for the same, but at terminal velocity please!

At cosmic velocity, something dense like that, the size of a tennis ball, would give you a free in-ground pool.

If that is iron, and spent a number of years on Earth, how come it's not rusting??

Is the nickel content preventing that??

Excellent series of posts. I have been of the opinion that asteroid mining would become profitable if they began with pallasite rich asteroids and sold the material for jewelry and luxury furniture.

The nickel helps, but they can rust if not stored properly. When found, the outside ablated surface does rust, but they are pristine inside when cut. Some collectors bathe them in alcohol and rub them down with some WD-40, but many like them as natural as possible and just store them in low humidity cases, if possible. Some particular pallasites, especially Brenham, can get lawrencite disease, which is an oxidation reaction between the iron and minerals surrounding the olivine if not prepared and stored properly.

There are jewelers who specialize in Pallasite jewelry. Usually Rings and Pendants.
A table made of a Pallasite slab would be an amazing thing (huge bucks).

Are you saying it is unwise to lick mine when it arrives?.

Ha!
It will not hurt you, but wash it first!
