I was curious about what you meant by 10 minutes sooner or 10 minutes later, so I found this [1]: > The discovery of the Chicxulub crater dramatically enhanced the community’s ability to evaluate the environmental effects of an impact at the K-T boundary, because both the geographic location of an impact site and the target rocks involved in an impact can affect the environmental outcome. For example, rocks composed of the mineral anhydrite in the Chicxulub target sequence imply that sulfate aerosols were injected into the stratosphere, affecting the radiative budget of the atmosphere (heating the stratosphere while cooling the Earth’s surface) before settling to the troposphere where they were washed out as acid rain.
