Title: What is this rock conglomerate?
Post by: joedesu1 on 08/08/2016 00:20:28

Hello all,
Total newbie here trying to determine what this is as well as its value.  I was told it was worth a lot, and have had this sitting outside for the last two years.  Id prefer someone take it and enjoy  it. I have it listed in ebay, but am wondering if that is a mistake.

Forgot some info.  Weight is around 160 pounds and measure roughly 19x18x10 inches

More like it would cost a lot for someone to take it away.
It just looks like conglomerate (https://en.wikipedia.org/wiki/Conglomerate_(geology)) : I can't see why that would have any value.

Ok thank you. People always think their stuff is worth its weight in gold but it's hardly the case. Appreciate the information and the comparison.

I agree with RD. Looks like some sort of conglomerate (rock composed of large rounded fragments) that is cemented with either quartz or calcite (I can't tell from the photos). Unique large specimen, but probably not worth much.

This was very helpful with a similar situation.I took a sample to the Geology Department of The Ohio State University in my home town of Columbus,Ohio.A gentleman there identified my sample as a piece of magnetite,rather than a meteorite as I originally surmised.His invaluable expertise was offered free of charge in a friendly manner.I would always seek expert advice of this sort from nearby educational institutions.

A Conglomerate Meteorite will might look like this May be some sort of Dhofar or something like new Found highland? but i haven't completely studied/tested this rock as yet.

To the naked-eye, a lunar meteorite without fusion-crust would be indistinguishable from [worthless] rocks which could be found on Earth.

Due to their extreme rarity, Lunar meteorites are worth more than their weight in gold.
That high-value means alleged lunar meteorites outnumber the real thing ... http://meteorites.wustl.edu/id/realthing.htm
