- Precambrian impact structures and ejecta on earth: A review
Impact cratering is an important geological process on Earth This review summarizes the state of knowledge of the Precambrian (Hadean, Archean, and P…
- Ejecta - an overview | ScienceDirect Topics
Ejecta refers to the material expelled from a target during an impact event, which can include coherent ejecta blankets, breccias, and melt rocks This material is categorized into proximal ejecta, which preserves target stratigraphy, and distal ejecta, typically composed of fine-grained rock and mineral fragments
- Ejecta from impact craters - ScienceDirect
The ejecta model, along with the constants given in Table 3, can be used to calculate the ejecta velocity distribution for a given impact event From those follow a number of important features, including range of ejecta, regolith on small bodies, momentum magnification for asteroid deflection considerations, and so on
- Ejecta - an overview | ScienceDirect Topics
Ejecta refers to the outflow expelled during and shortly after the collision of two neutron stars, consisting of various components such as dynamical ejecta driven by tidal forces and shocks, as well as post-merger ejecta from processes like disk winds These components exhibit different speeds and interactions, with the majority moving at velocities between 0 1c and 0 3c AI generated
- Ejecta distribution and momentum transfer from oblique impacts on . . .
Ejecta scaling relationships are useful to determine the ejecta mass–velocity distribution and momentum transfer for vertical impacts scenarios other than the ones considered here
- Spatial and shape distributions of ejecta from hypervelocity impact . . .
Hypervelocity impact experiments of rock projectiles and steel targets were conducted at velocities ranging from approximately 3 km s to 7 km s Eject…
- A conceptual model for the formation of ramparts on Martian impact . . .
In this model, impact events produce ejecta curtains that advance radially at increasingly higher velocity outward excavating and roughening the surface as they impact This produces an inertia-driven, ground-hugging ejecta flow composed of primary and secondary ejecta
- Paleoenvironment implications of layered ejecta craters in the Chryse . . .
The formation of martian layered ejecta craters (LECs), which have one or multiple distinctive fluidized layered ejecta deposits, is generally hypothe…
