Safe answer: The Chicxulub Impact
| The Chicxulub Impact | 4 days ago · Named the Chicxulub impactor, the meteor produced clouds of dust and ash and catapulted fragments of rock into the sky, triggering widespread wildfires. Over time, the devastating impact drove the extinction of around 75 percent of all plant and animal species on the planet, including all terrestrial dinosaurs.

Although the overall agreement in eruption duration is an achievement for geochronology, it is important to clarify. |

It maintains its velocity until impact, plunging through the entire 60 miles of atmosphere in fewer than three seconds. The asteroid screeches over Central America, emitting a sonic boom that reverberates across the continents. 3 days ago · Abstract.

Chicxulub: The Asteroid that Killed the Dinosaurs The Chicxulub Impact.
Zhang, Wei-Qi ; Liu, Chuan-Zhou ; Dick, Henry J OctoberJournal of Petrology Abstract The architecture of lower oceanic crust at slow- and ultraslow-spreading ridge is diverse, yet the mechanisms that produce this diversity are not The Chicxulub Impact understood. Particularly, the km2 gabbroic massif at Atlantis Bank Southwest Indian Ridge exhibits significant compositional zonation, representing a high magma supply end member for accretion of the lower ocean crust at slow and ultraslow-spreading ridges. Olivine gabbros away from the shear zones have mineral trace element compositions indicative of high-temperature reaction with an oxide-undersaturated melt.
By contrast, olivine gabbros within shear zones display petrographic and chemical features indicative of reaction with a relatively low-temperature, oxide-saturated melt. These features indicate an early stage of primitive to moderately evolved melt migration, followed by deformation-driven transport of highly evolved Fe-Ti-rich melts to high The Chicxulub Impact in this gabbroic massif. The close relationship between shear zones and the reaction with oxide-saturated melts suggests that syn-magmatic shear zones provide a conduit for late-stage, Fe-Ti-rich melt transport through Atlantis Bank lower crust. This process is critical to generate the compositional zonation observed.
Thus, the degree of syn-magmatic deformation, which is fundamentally related to magma supply, plays a dominant role in developing the diversity of lower ocean crust observed at slow- and ultraslow-spreading ridges.]
