  Mounds of North America - Crystalinks
It is located on a plateau with a unique cryptoexplosion structure that contains faulted and folded bedrock, which is usually either produced by a meteorite or volcanic explosion.
This cryptoexplosion structure has caused Serpent Mound to become misshapen over the years.
In 1947 R.D. Dietz in Science magazine suggested that a better name to describe the land features was "cryptoexplosion" - the folded and faulted beds of landforms from different geologic eras exposed from the impact of meteors.

The magmatites of the mining area are subvolcanic rocks of late phase of volcanic activity, which are found in the volcanic pipelines and creaks.
Rocks here include porphyry rhyolite, quartz porphyry, quartz porphyry, ryyo-cryptoexplosion breccia conglomerate, Cryptoexplosion breccia conglomerate, etc., which normally takes the nervation shape and runs in north-west direction, with length ranging from tens of meters to hundreds of meters and width between several meters to tens of meters.
In the area of the Erbaohuo project, alteration is caused by middle to low temperature hot liquids in which silica is the most extensive and significant form of alteration, and relates closely to the formation of silver mineralization.

 ORIGIN OF THE SERPENT MOUND CRYPTOEXPLOSION STRUCTURE: EVIDENCE FROM X-RAY DIFFRACTION STUDIES
The rocks at the Serpent Mound disturbance exhibit complex faulting in contrast to the fairly flat-lying sedimentary rock beds of the surrounding country.
The Serpent Mound disturbance is referred to as a cryptoexplosion structure and is though to have originated from some powerful explosive event.
We are testing the two hypotheses by x-ray diffraction analysis of quartz grains from the Serpent Mound cryptoexplosion structure.

." Cryptoexplosion literally means "mystery-explosion." The Serpent lies in an area nearly 5 miles in diameter which has been faulted, folded and twisted by two immense explosions.
The Serpent lays upon a high area created by the cryptoexplosions and overlooks a plain and a small river.

 MYSTERIOUS WORLD: Spring 2003: Serpent Mound Part I: Great Serpent
This rendering of the serpent mound acropolis is from Squier and Davis' classic survey of Native American mound structures, Ancient Monuments of the Mississippi Valley, originally published in 1848.
The Serpent Mound cryptoexplosion structure is an unusual geological feature, about five miles in diameter, centered at the common boundary of Adams, Highland, and Pike counties.
This may be caused by substantial iron ore deposits that were pushed up by the cryptoexplosive event, iron ore deposits in the nearby Brush Creek, the existence of a 3-ton solid steel observation tower on the south side of the site, or perhaps a combination of all three.

 Geotimes - March 2004 - Wisconsin crater revealed
The crater’s discovery is not only important to understanding the local geological picture, but also may have greater significance to the discovery of impact structures in sedimentary rocks around the world.
In 1985, William Cordua, a geologist at the University of Wisconsin-River Falls and co-author on the paper, first reported that the Rock Elm structure had the characteristics of a cryptoexplosion structure: a circular outline with intense localized deformation, a central uplift and the absence of intrusive igneous rocks or salt domes.
He could not, however, tie the structure to an impact.

 Background:
On Earth, there is one basic difference used in the classification of craters, age.
Older or more eroded craters are called astroblemes, or cryptoexplosion structures.
The only distinguishing characteristics of the oldest craters are their circular shape and the presence of breccia, the original rock fragments that formed from the impact of the asteroid.

Eight circular geologic structures ranging from ~3 to 17 km in diameter, showing evidence of outward-directed radial deformation and intensive brecciation, lie within a linear swath ~15 km wide along a straight line stretching ~700 km across the United States from southern Illinois through Missouri to eastern Kansas.
Based on their similar geological characteristics and the presence of diagnostic and/or probable evidence of shock, these structures, once classified as 'cryptovolcanic' or 'cryptoexplosion' structures, are more confidently ascribed to hypervelocity impact.
No other similar occurrence of aligned features is known, and we calculate the probability of a chance alignment to be

The majority of lunar craters and known terrestrial cryptoexplosion features such as Gosses Bluff, Australia (Milton and others, 1972), and the Arizona Meteorite Crater are commonly recognized as impact structures.
Such features, similar in form to craters produced by chemical or nuclear devices, result from the release of energy at or below ground level caused by impact of a rapidly moving mass.

The Dictionary of Geological Terms defines a shatter cone as
"A distinctive striated conical fragment of rock along which fracturing has occurred, ranging in length from less than a centimeter to several meters, generally found in nested or composite groups in the rocks of cryptoexplosion structures, and generally believed to have been formed by shock waves generated by meteorite impact.
Shatter cones superficially resemble cone-in-cone structure in sedimentary rocks; they are most common in fine-grained homogeneous rocks such as limestone and dolomite, but are also know in shale, sandstone, quartzite, and granite.
