Sparkplug in a Geode




The Coso Geode

In 1961 a fossil encrusted geode was picked up in the Coso Mountains, six miles northeast of Olancha, California, near the top of a 4300' peak overlooking the dry bed of Owens Lake by some rock hounds. What was discovered after it had been cut in half is something that has caused much debate over the years, and continues to this day. In the middle of the geode was a metal core approximately .08" in diameter. Encircling this was what appeared to be a ceramic casing which was also surrounded by a hexagonal sleeve of wood, which had become petrified. This was encased by the outer layer of the geode which was made up of hardened clay, pebbles, and bits of fossil shell, and two nonmagnetic metallic objects resembling a nail and a washer.

Here is what an X ray of the Geode looked like :

Spark Plug

"This what the rock hounds saw when they cut it in half. X-rays of the objects were taken and examined by Paul Willis, then editor of INFO Journal who noticed a startling similarity between it and a modern spark plug. An unnamed geologist in the original report of the find came up with an age estimate of 500,000 years based on the fossils contained in the matrix (note-this would not indicate what date the accretion was formed)."

"First, the object is most definitely not in a geode. They were out hunting geodes but the object itself, as Wikipedia notes was "encased in a lump of hard clay or rock."

The article stated that the discoverers called it a Geode regardless of what the author of the wiki article says but this is a moot point cause they ruined a diamond saw cutting open the "rock". A rock by any other name is still a rock.

"Second, the object here has been positively identified as a 1920's era Champion spark plug which became encased in a concretion composed of iron derived from the rusting spark plug. The formation of this iron oxide nodule was probably accelerated by the fact that corrosive "mineral dust" is blown off Lake Owen's dry lake bed and up onto the adjacent uplands where the artifact was discovered."

No, it has not been positively identified as a 1920's era Champion spark plug nor does the article state that. The article states that these people "suggested" it was similar to a spark plug of that era. See quote following from the wiki article.

"An investigation carried out by Pierre Stromberg and Paul Heinrich, with the help of members of the Spark Plug Collectors of America, suggested that the artifact is a 1920s Champion spark plug."

I also noticed that wiki failed to mention a fourth suggestion as to the origins of the plug and that was Antediluvia.

"Yes its concretion. And no, that isn't a "rock.""

Well, that's funny, cause the article you posted said it was a rock, not a concretion and that 'concretion' destroyed a diamond tipped saw that was used to cut it in half. Talk to your buddy the diamond saw maker and ask him how that was possible since they use those things to cut through solid granite.
