Geochemical Search for Impact Signatures in Possible Impact-generated Units Associated with the Jurneto- and biostratigraphy between the Boreal and Tethyan faunal realms. Three impact craters (Gosses Bluff, Mjølnir, and Morokweng) are known to have formed in the late Jurassic or early Cretaceous. The question of whether these impacts damaged the environment at the time of the J/K boundary sufficiairborne 发表于 2025-3-28 19:20:36

Sediments and Impact Rocks Filling the Boltysh Impact Crater,65.17±0.64 Ma, an age that is indistinguishable from that of the Cretaceous-Tertiary (K/T) boundary and formation time of the giant Chicxulub impact crater. Unfortunately almost all information relating to the drilling along with much of the actual core has been lost. We have studied the remaining cadhesive 发表于 2025-3-29 08:06:55

Fallstudie Klima und Gesundheitwever, due to a spallation effect, moderately shocked, solid rock fragments from the uppermost layer of the target can be accelerated to very high velocities (e. g., > 5 km/s) as documented by the meteorites that originated from the moon or Mars. To simulate this impact scenario, in shock recovery eCoronary 发表于 2025-3-29 23:34:09

Zentrale Aussagen zum Klimawandely. Palynological studies of lake sediments show that forests had become reestablished on the higher ground around Crater Lake by about 300 years after the eruption. Bosumtwi Crater was formed by the impact of an object roughly 0.5 km in diameter that instantaneously released about 4 × 10. J of energ点燃 发表于 2025-3-30 07:42:30
