Lattice defects in lawsonite have been studied by transmission electron microscopy. It is proposed that twinning and easy glide systems are 1/2[110] {110}; the easy glide planes are coincident with twin planes. This mineral displays high sensitivity

In recent years, apparently shock-induced and, thus, impact-characteristic microdeformations, in the form of planar microdeformation features and so-called strawberry (granular) texture, have been observed in zircons in rocks from confirmed impact st

Ion probe determinations of water concentrations and D/H ratios have been performed on different phases (pyroxene, olivine, and mesostasis) of chondrules from the Bishunpur and Semarkona LL3 chondrites. Mean water concentrations average 1290 ppm in o

San Carlos olivine samples enclosed in soft iron capsules were annealed in an uniaxial split-sphere apparatus, at pressures ranging from 4.6 to 9.0 GPa and temperature ranging from 1310o to 1595 oC. We estimated the annealing fO2, theoretically contr

Quartz has the chemical composition SiO 2 . It is an abundant mineral in the Earth crust and its mechanical properties govern the rheological behaviour of a number of crustal rocks. Quartz is also a material widely used in industry (resonators, filte

Shock waves induce peculiar defects in quartz: shock mosaics, high-pressure polymorphs (coesite and stishovite), diaplectic glass and ‘planar deformation features’ (PDFs). Together, these features are the indices of ‘shock metamorphism’, PDFs

We have investigated by Transmission Electron Microscopy (TEM) the planar deformation features(PDF) in quartz from various sites where shock metamorphism has been detected optically: impact sites; the Vredefort complex (South Africa) and the K/T boun

The classical solid-medium apparatus (Griggs apparatus) is generally viewed as a machine of poor accuracy with a large amount of uncertainty. However, a new generation of equipment with new assemblies and experimental procedures has greatly enhanced

We present a detailed investigation by transmission electron microscopy (TEM) of the fine structure of planar deformation features (PDF) in quartz grains within which shock metamorphism has been detected optically and which originate from various sit
