Is Your Rock a Real Meteorite or a Common Meteorwrong?

In summary, the stone looks like an Ordinary Chondrite, it's been on Earth for a long time, and there is evidence of metal spread throughout the rock. However, a lab test would be the final confirmation.

TL;DR Summary
Iam in the process of getting an authority to either confirm or decline it as a proper meteorite. When I looked up for photos on internet it looked exactly like a meteorite. Now talking about stone it appears to have fusion crust, it is magnetic and possible metal flakes. Really needs some experts help.

While we get to Australian time, let's start with the bad news:

1. A photograph cannot prove a stone is or as not a meteorite. You need to send it to a lab. Labs expect to be paid, evem if the answer is "no".
2. Most rocks thought to be meteorites are not, so the odds start out against you..

Relevant features:
  • Magnetic - moves the odds up, but lots of earth rocks are magnetic too.
  • Fusion crust - I don't see one. Do you have a section? (Is that what the 2nd to last picture is supposed to show) All I see is that the outside is dark. Lots of rocks have a dark outside.
  • Regmaglypts - Don't see any. Moves the odds down.
  • White mineral - if this is quartz, it is not a meteorite.

looks like a very good Ordinary Chondrite to me
Has the remains of a very old and weathered fusion crust. It's been on Earth a very long time and the crust is no longer black
The shiny "white/silver" material looks like the Iron just shing cuz of the angle the photo was taken relative to the stone
The spread of that "metal" throughout the rock is indicitive of how metal is spread in a choncrite

Like this australian one from my collection .....

When a rock has been reasonably metamorphosed at it's source, it can destroy many/most of the chondrules

cheers

PS. After Berkeman's comment, I thought I better do an edit
Ordinady Chondrite is the most common type of meteorite
Chondrites make up 85.8% of stony meteorites. Stony meteorites make up 93.8% of all meteorites.
Stony-Irons another 1.2% and Irons 5%

So at the end this is a meteorite right? My first meteorite and literally a dream come true! It won't matter to mean if it is very comman or rare iam just going to keep it with me as my first meteorite ☄

I have no reason to believe that it isnt. A lab test would be the final confirmation.
I have been collecting meteorites ( and rocks and minerals - for that matter) for a long time.
I have over 300 meteorites in my personal collection and over 500 rock and mineral specimens.
Every day in various Facebook groups I see and tell many people that they have meteorwrongs
instead of meteorites. 99% of rocks that are shown (asked about) in the groups are meteorwrongs.
Slag from glass or iron foundaries is most common, volcanic rocks such as basalts also a very
common wrong

I would love to see a better/sharper photo of that cut surface

Also, where did you find this rock ... Home country ? which is where ?

As @Vanadium 50 said, magnetic attraction isnt a good proof. Many Earth rocks are also
attracted to a magnet and on the other hand, not all meteorite are attracted to a magnet.
For example, achondrites that include Martian, Lunar and the Vesta asteroid H.E.D. groups
are almost to completely devoid of metal and therefore wont stick to a magnet.

Iron in chondrite meteorites is sprinkled through the rock like in your and my samples.
Iron and other metals in Earth rocks tends to be more clusteres along seams as much of
it is hydrothermally deposited ... ythink veins of gold, copper, antimony etc etc
Iron in Earth deposits tends to be in bulk mass and often heavily oxidised in the forms of
limonite, magnetite, hematite etc. Physical, metallic, iron in the Earth's crust is extremely rare
In fact, probably, 98-99% of that which is found would be in meteorites.

Metallic iron is found in 3 type of meteorites
1) stones as in chondrites - this is crustal material of asteroids
2) Stony-Irons as in Pallasites and Mesosiderites they are from the mantle and the mantle-crust
boundary of an asteroid
3) Irons as in Nickel-Iron meteorites from the cores of broken up asteroids

iam from india. And it was found in my backyard. Since a year I was watching videos, photos ,websites and threads related to meteorites. Since then I wanted a meteorite really bad. I could not go for meteorite hunting anywhere (since iam 15 years of age) so I decided to take a chance and test my luck. I tried to find a meteorite in my backyard as it was filled with rocks. It is still unbelievable that a space rock was resting in my backyard and didn't knew! Here are some photos of cut sections with some metallic flakes visible and sorry for poor quality of images.

FAQ: Is Your Rock a Real Meteorite or a Common Meteorwrong?

What are the key characteristics to identify a real meteorite?

Real meteorites often have a fusion crust, which is a thin, dark, glassy coating formed as the meteorite melts during its passage through the atmosphere. They are typically dense and magnetic due to their high metal content, primarily iron and nickel. Additionally, they may display regmaglypts, which are thumbprint-like indentations on their surface.

How can I test if my rock is magnetic?

To test if your rock is magnetic, you can use a simple magnet. Hold the magnet close to the rock and see if it is attracted. Most meteorites contain iron-nickel metal, which will cause them to be magnetic. However, keep in mind that not all magnetic rocks are meteorites, as many terrestrial rocks also contain iron.

What is a fusion crust, and how can I recognize it?

A fusion crust is a thin, dark, often shiny layer on the surface of a meteorite that forms when the outer layer melts and solidifies as the meteorite passes through the atmosphere. It usually appears as a black or dark brown coating and can be distinguished from the interior of the rock, which is often lighter in color.

Are there any common terrestrial rocks that are often mistaken for meteorites?

Yes, there are several common terrestrial rocks that are often mistaken for meteorites, known as "meteorwrongs." These include magnetite and hematite, which are iron-rich and magnetic, as well as slag, a byproduct of industrial processes that can have a similar appearance to meteorites. Additionally, volcanic rocks like basalt can sometimes be confused with meteorites.

Can a laboratory analysis confirm if a rock is a meteorite?

Yes, laboratory analysis can definitively confirm if a rock is a meteorite. This typically involves examining the rock's mineralogy, structure, and chemical composition. Techniques such as scanning electron microscopy (SEM), X-ray fluorescence (XRF), and mass spectrometry can be used to identify the presence of extraterrestrial minerals and isotopic ratios that are unique to meteorites.
