Discussion Overview
The thread revolves around the appreciation of geologists and their passion for geology, including personal anecdotes and experiences related to identifying rocks and meteorites. It touches on the value of conversations with geologists and the nuances of distinguishing meteorites from Earth rocks.
Discussion Character
- Exploratory
- Conceptual clarification
- Debate/contested
Main Points Raised
- Some participants suggest that the best geologists are driven by their fascination with geology rather than financial incentives.
- There is a proposed method for engaging geologists by presenting them with rock samples during a casual dinner, which may lead to valuable conversations and stories.
- One participant shares their experience with identifying meteorites, noting that many people are disappointed to learn their rocks are not meteorites.
- A participant mentions their extensive collection of meteorites and discusses the misconception that meteorites do not have vesicles, citing recent discoveries that challenge this belief.
Areas of Agreement / Disagreement
Participants express a shared appreciation for geologists and their work, but there is no consensus on the specifics of identifying meteorites or the implications of recent findings regarding vesicles in meteorites.
Contextual Notes
There are unresolved assumptions regarding the identification of meteorites and the criteria used to distinguish them from Earth rocks. The discussion reflects personal experiences and anecdotal evidence rather than established scientific consensus.

You might hire a geologist with a degree, but the best geologists are fascinated by the geology, not the money.
To identify strange rocks, minerals, or fossils, place the samples in the middle of the table, invite the geologist to a family dinner, hand them a drink, and answer any questions they ask you. The conversation, and the stories you will hear, will be worth more than money can buy.

When it comes to rocks that may be meteorites, I get asked this question a dozen times a day.
I find that most people 75% or so hate being told that their "precious" rock is just an Earth rock
and not a meteorite.
With over 450 meteorite samples ( some approx. 400 different meteorites) in my collection,
There's only a few oddball ones that I cannot look at and definitively say Yes or No to it
being a meteorite
We were all told, for many years, that meteorites didnt have obvious gas bubble holes (vesicles) in them.
But over the last several years, that has proven to be wrong as there has been found several meteorites
with obvious vesicles in them. One of these being Jikharra 001, from Ajdabiya, Libya.
I added a large slice, 370grams, of this to my collection late last year.
It's been classified as a eucrite melt breccia, one of the H.E.D. group of achondrites with asteroid 4
Vesta origins.
cheers
