Frictional melting is the result of the conversion of mechanical deformation to heat under
adiabatic conditions of slip. Within planetary materials, which are mainly natural ceramics, …

High-speed slip experiments performed on Westerly granite using friction welding apparatus
reveal that comminution is an essential precursor to melting by friction. Observations of slip …

Evidence is presented for a special type of fault characterized by a very large displacement (≥100
m) occurring during a single-slip event at seismogenic velocity (>0.1 m ṁ s −1 ). I …

It is understood how rocks are made on Earth. However, on the Moon, Mercury, and, to a
lesser extent, Mars and Venus, there are distinct rock-forming processes that we do not fully …

Under conditions of coseismic slip (0.1–2.0 ms −1 ) within the upper crust, differences in the
shear yield strengths, fracture toughnesses, melting points and, to a lesser extent, thermal …

Evidence for the collision of fragmented comets or asteroids with some of the larger (jovian)
planets and their moons is now well established following the dramatic impact of the …

Analytical scanning electron microscopy has been used to determine the major element
compositions of some natural and artificial silicate glasses and their microcrystalline equivalents …

A 150 μm thick fused layer of rock has been produced by rotating two metadolerite core faces
against each other at 3000 rpm under an axial load of 330 kg for 11 s using friction welding …

The mobilization of alkali metals in alkali silicate glasses and certain minerals during
electron-microprobe analysis is a result of beam-induced heating and charging effects within the …

The Windjana drill sample, a sandstone of the Dillinger member (Kimberley formation, Gale
Crater, Mars), was analyzed by CheMin X‐ray diffraction (XRD) in the MSL Curiosity rover. …
