The extinction of the dinosaurs and around three-quarters of all living species was almost
certainly caused by a large asteroid impact 66 million years ago. Seismic data acquired …

More than 50 years of space and planetary exploration and concomitant studies of terrestrial
impact structures have demonstrated that impact cratering has been a fundamental process …

When hydrated, phosphides such as the mineral schreibersite,(Fe, Ni) 3P, allow for the
synthesis of important phosphorus-bearing organic compounds. Such phosphides are …

A hydrothermal system is an environment where there is a flow of hot fluids beneath and up
to the surface of the Earth. Hydrothermal vents are systems whose heat source is the …

Impact craters are common surface features on planetary surfaces. Their distribution offers
important clues regarding geological and temporal processes on the Moon. Numerous …

A geologic time scale is a chronological system that separates the geological strata of a
planetary body into different units in temporal sequence and shows its progressive …

On the Moon, the old anorthositic highland rocks and younger basaltic mare units show
distinguishable differences in appearance. The craters on the lunar highlands and maria …

Impacts are central to the origin and evolution of planets of the Solar System. The shapes of
craters, which can reach up to 1,000 km in diameter on the Moon, provide critical information …

Understanding the formation of impact craters on planetary surfaces has fundamental
importance in geology, impact dynamics, and planetary sciences. The finite element …

Abstract The Ries impact structure (Germany) contains well‐preserved ejecta deposits
consisting of melt‐free lithic breccia (Bunte Breccia) overlain by suevite. To test their …
