For the last several weeks, natural gas has been been
bubbling fairly steadily from Corne Bayou in Assumption
Parish where it overlies the Napoleoville Salt Dome.

determined that the potential failure of an inactive salt-
mining cavernnear the area, which was closed in 2011,
is likely the cause of the sinkhole and recent bubbling."

The Caterpillar mimetolith outcrop in Louisiana

What's the term for when a meteorite resembles an object? (Mimetoliths)

Wednesday, April 7, 2010 9:03 PM

Yinan Wang asked:

"Whats the term for when a meteorite resembles an object?"

The term that you are looking for is "mimetolith." A web page about
mimetoliths by Dr. R. V. Dietrich can be found at:

http://www.cst.cmich.edu/USERS/DIETR1RV/mimetoliths/

"mimetolith - 1.
a. a natural topographic feature, rock outcrop, rock specimen,
mineral specimen, or loose stone the shape of which resembles something else
-- e.g., a real or fancied animal, plant, manufactured item, or part(s) thereof.

b. a topographic feature, rock outcrop, rock specimen, mineral specimen, or
loose stone, the surface pattern of which resembles a real or fancied animal, ... .

c. a topographic feature (et alia) with any combination of shape and pattern
that resembles a real or fancied animal, . . . . [Greek mimetes (an imitator)
and lithos (stone); term coined by Thomas Orzo MacAdoo, first appeared in
(Dietrich, 1989).]"
