Iridium Anomaly (5 cent)?

[Capiert]

Where is the nickel?!

 

For about 65 million years ago, GMT (Greenwich Mean Time),

 a terrible, immense, explosion

 occured over the gulf of Mexico

 leaving (th)a(t) (great=big) crater there.

 

All over the earth, 2 layers of iridium (sediment)

 (with quartz),

 are found in the rock sediment (clay),

 ruffly each (layer) are about 1 cm thick

 & spaced=separated about 1 cm apart.

 

Please notice:

Meteorites are (extraterrestrial (origin)) iron "nickel" rocks

 coming from outer space.

 

Typical example: Sudbury mines (company) Ontario, Canada,

 extract the(ir meteor's) nickel

 from the ore;

 & a small percentage of that nickel

 has platinums;

 & a small percentage of those platinums

 is iridium.

 

Thus iridium is an extraterrestrial metal

 but should be only a tiny percent

 of a nickel ore.

 

But according to the iridium anomaly (hypothesis)

 it(s percentages pyramid) is the other way around.

Instead of finding (small percentages of) iridium

(mixed) in nickel (ore) sediment,

 we find only iridium

 as though nickel never existed (in the 2 layers) at all.

 

My big question (here) is,

 where is(=has) the nickel (gone)

 for such a (so_called) meteorite (explosion)?

 

--

 

Otherwise,

 there is no indication

 that the earth was "struck" by a (nickel containing) meteorite

 ~65 million years ago.

I.e. None, =no evidence

 to support the meteorite (struck the earth) hypothesis.

 

Thus the meteorite ("stuck") hypothesis does NOT make sense.

=It's NON_SENSE, =NOT based on facts.

No(t enough) nickel was found

 (by the explosion site)

 to validate the hypothesis

 (that a meteorite hit the earth).

 

E.g. Was it a meteorite

 that caused the explosion?

If not? What then (was the cause, for the explosion)?

 

Instead an above earth explosion seems

 more possible.

But that (=because) pure iridium was the fallout (dust),

 indicates an atomic nuclear explosion

 of severe (radiation) intensity. 

E.g. (Increasing by_products (=residue (mass), tendency) 

 due to radiation, produces mass):

 I-131 (8 days), Cs-137 (30 years) & Sr-90 (29 years), Si-32 (153 years), Ir-192(m2 241 years, 2nd densest, earth metal), .. .

(as ruff (approx.) idea, but those are the unstables).

 

A kind of fusion (produced mass, similar to pair production)

 caused by too much (gamma) radiation.

 (E.g. producing larger mass

 (e.g. transmutation, nuclear chemistry);

 & it is (also) an indication of atomic mass's age.

But that's another theme, on its own.)

 

2.

I'll assume, even though iridium is the 2nd densest metal,

 aerosol floating would (have) be(en) possible

 to carry it (Ir dust) far distances,

 all over the earth('s surface).

Otherwise, that Ir smoke

 would have landed locally,

 e.g. near the crater

 (to some extent);

 instead of throughout the whole earth's surface.

But I still find it peculiar

 to think a meteorite struck,

 (that it)

 could have been vaporized

 to release its (nickel's) iridium,

 without a single trace,

 of iron, nickel nor platinums.

May have been a chondite. Different composition and actually more common.

Quote

Chondrites can be differentiated from iron meteorites due to their low iron and nickel content. Other non-metallic meteorites, achondrites, which lack chondrules, were formed more recently.

This is a good question, and good thinking on your part as far as it goes. +1

But do you have any evidence that nickel was tested for and found absent or not present in enhanced quantities?

What is the normal concentration of nickel?

the so called iridium spike of Alvarez was found to be an increase of 30 times from 0.3 parts per billion to 10 parts per billion

I think that nickel and iron are more abundant that that.

It is an interesting exercise to take an average % nickel for (say 20%) the chixelub meteorite and calculate what increase it would make to the average  crustal concentration of the Earth if spread out over it.

Would it produce as spectacular a spike ie increase the concentration by a factor of 30?
