Zhamanshin (Kazakh: Жаман шың, romanized: Jaman shun) is a meteorite crater in Kazakhstan. It is 14 kilometres (8.7 mi) in diameter and the age is estimated to be 900,000 ± 100,000 years (Pleistocene). The crater is exposed at the surface. [1]

Zhamanshin crater is a 13.5 km diameter circular meteorite impact structure located about 40 km southwest of the village of Irghiz, Kazakhstan. Approximately one million years in age, the locality is best known for its Irghizites, beautiful little droplets and ropy ribbons of vitreous jet-black glass.

Jan 1, 2020 · The Zhamanshin structure is the only crater known to contain aerodynamically shaped and tektite-like objects (irghizites), as well as several varieties of impact glasses, called zhamanshinites (e.g., Florenskij, 1977).

Today, all impact databases indicate an apparent diameter of 13-14 km for Zhamanshin crater [2,3]. This would make Zhamanshin the 2nd largest impact crater of the Quaternary. In this study, we use new geophysical data to bet-ter constrain the …

Jan 1, 1992 · The BIC resembles pristine complex craters on the Moon to first order (i.e., 'U'-shaped topographic cross section with preserved rim), while the ZIF displays virtually none of the typical morphologic elements of a 13- to 14-km-diameter complex crater.

Mar 1, 2016 · Meteorite crater Zhamanshin is very interesting in the point of view of archaeology. It’s a well-known fact that for a long time there was a lake in the crater. Probably this circumstance attracts ancient people to this place.

Jun 26, 2019 · Zhamanshin is located in a semi-desert area less than 200 km north of the remnants of the Aral Sea. It has a 6-km-wide inner crater basin partly filled with lake deposits, an inner rim, and an about 50-m-high outer rim both partly eroded and made up …
