There is still no agreement on the formation of the tektites. We make arguments for the rheological ignimbrite mechanism. It was shown by modeling [11] that the dense ignimbrite currents could be the source for deposits of the Ries crater. Moldavites are considered as distal deposits of the Ries crater. We assume both moldavites and other fields of...

В книге рассмотрены вопросы исследования земных кратеров и т.н. криптовзрывных структур (наиболее подробно - кратеры Рис и Штайнхайм), а также происхождения тектитов на нашей планете. Положение дел в сегодняшней метеоритике, на наш взгляд, требует пересмотра основ. Новые данные, связанные с необычными регистрациями на Тасмании в период Тунгусского...

В частности, акцентируется внимание на различии эффектов, вызванных Тунгусским феноменом летом 1908 г. и взрывом Челябинского астероида в феврале 2013 г. Несмотря на «назначение» в связи с Тунгусским феноменом 30 июня международным «Днем астероида»...

Despite the "appointment" on June 30, in connection with the 1908 Tunguska event, the international "Asteroid Day", evidence of the fall or explosion of a meteoroid in Siberia has not yet been presented. Hundreds of expeditions in the alleged epicentre of the explosion in search of traces of a meteoroid have not yet yielded the desired result. The...

The growth of the Arago and Babinet neutral polarization points, which began in May 1907, continued until the Tunguska explosion of 1908 when their maximum relative increase for the entire period 1905-1909 record. Before the Tungus explosion on June 30, 1908, the appearance of luminous clouds over Europa on April 30, 1908, May 27, 1908, and more po...

Since huge sunspots/eruptions were observed on June 27-30, 1908, a 3-minute pulsations period in Kiel can be caused by resonance with the "acoustic halo" of global earthquakes of the Sun, having a frequency of 5-7 milliHz, i.e., 3-min. period. On June 27 and 28, 1908, the registration of the geomagnetic pulsations beginning in Kiel at 18 LT coincid...

On June 30, 1908, explosions of volcanic pipes during an earthquake in the Siberian craton could cause gas eruptions along with stones and, therefore, the illusion of a meteor. In Petersfield, England, according to the microbarogram, was obtained pressure waves travel speeds: 323 km/s for the onset at 5 h. 10 min. and 308 km/s for the sharp shock a...

The 1908 Tungus explosion occurred exactly in/over the kimberlite paleovolcano, which had five stages of activity from the times of Siberian Flood Basalts (252 Myr) to the 1908 blast. All events were, probably, connected with the 'Perm LLSVPs Anomaly' located under Eurasia on the core-mantle boundary. Since moissanite minerals were found in layers...

In the article [Ginneken, M. et al.

However, many arguments suggest that the detected particles may b...

The 1908 Tunguska event was not related to the Earth's collision with a comet/asteroid and could be most probably a tectonic event caused by solar-lunar-terrestrial perturbances. The evidence: 1. The polarization effect 'spread' from the lower to the upper atmosphere, and not vice versa, as would be expected in the case of the penetration of come...

This article provides a new explanation of the Tunguska event of 1908. The basis is the interpretation of geomagnetic pulsations recorded in Kiel (Germany) on June 27-30, 1908, as well as atmospheric fluctuations recorded by English barograms on June 30, 1908.

The frequency of ordinary chondrites as impactors is a paradox Ordinary chondrites are the most frequent projectiles for the Earth's impact craters. During the last 500 My, only the Chicxulub and Zhamanshin craters can 'drop-out' from this trend because of supposed carbonaceous chondrites impactors. Such frequency of ordinary chondrites is a parado...

В презентации доклада на EGU2020 рассматривается связь Тунугсского феномена 1908 г. с т.н. зонами снижения сейсмоволн (LLSVPs), расположенных на границе ядро-мантия Земли и триггерирующих активность мантийных плюмов. Корреляция между Пермской LLSVP аномалией и центром Тунгусского феномена 1908 г. позволяет утверждать взрыв мантийного палеовулкана,...

It is generally accepted that the Tunguska event in Siberia on 30 June, 1908 resulted from an explosion of cosmic body. However, there is no common agreement that this bolide really existed. Large low-shear velocity provinces (LLSVPs) are linked to so-called blobs located atop the Earth's outer core [1]. It was shown the Earth's D"-layer core/CMB/...

Since meteorites could not have caused the earth uplift in Tasmania, the impact hypothesis for the Tunguska phenomenon can be excluded. All data favor an endogenic origin of this event due to lunar-solar perturbations and the whole-mantle convection.

Probably, the reference of craters to astroblems according to PGEs/siderophiles concentrations in their melted rocks, could be unreliable because these elements are present in the Earth сore/mantle.

The ICP-OES plasma method till 2000 was imprecise. Therefore, the Bosumtwi crater most likely is endogenic, and the chondrite component in IVC-3395 can be the result of an explosive obduction.

Enigmatic discoveries made by the Mars Rover Opportunity at the Meridiani Planum landing site are so-called 'blueberries spherules' [1]. They show similarities to terrestrial tektites, and in addition, strong spectral signature of hematite [1]. We assume that the formation mechanism of 'blueberries' is related to dense (rheo)ignimbrite currents, an...

In this thesis the origin of the Ries and the Steinheim craters is discussed. Since both the ancient astenospheric uplift and tracks of the mantle plume under the Urach diatremes field are discovered [18], we assume that the hotspot of the plume could have moved from Urach towards the East through the Steinheim-Ries basin in Miocene. It could have...

The reference of craters to astroblems according to the PGEs/siderophiles concentrations in their melted rocks could be unreliable because these elements are present in the earth сore/mantle.

We assert that the determination of cosmic components in many earth craters by means of the chromium (Cr) isotope ratios are doubtful because of both technical problems by MC-ICP-MS method and incomplete estimatеs of several physical factors. The difference in Cr isotope ratios between the Earth and meteorites, as authors of this method claimed, i...

Since both the solar flare and the anomalous lunisolar tide during the Tunguska event in 1908 could have led to the disturbance of the Earth's core-mantle D'' layer, it could have triggered plume tectonics by means of the large low-shear velocity provinces (LLSVPs) convection, etc. Probably, the so-called Cosgrove hotspot did not lose an activity f...

The period of the Moon's longitude discrepancy also includes the year of the 1908 Tunguska event. Therefore, one may assume the Moon passage through a stream of the Sun's scalar waves during the eclipse on June 28, 1908. In addition, scientists observed magnetic vortical structures and a large protuberance on the Sun at that time. Formation of the...

No previous explanations for the optical mystery of the Tunguska event are wholly satisfactory.
