recent advances in understanding the geology of diamonds

Preface

Recent technological advances in transmission electron microscopy (TEM) have made it possible to discover various types of high-pressure polymorphs such as α-PbO 2 –type SiO 2 (seifertite) and ilmenite-type MgSiO 3 (akimotoite) The shock-induced textures are also useful in estimating the conditions of collision of the planetesimals in the

Recent advances in understanding Antarctic subglacial

1 Introduction and background Antarctic subglacial lakes were first detected using radio-echo sounding (RES) in the late 1960s [] from a geophysical survey of the Antarctic Ice Sheet that took place between 1968 and 1979 [] Subglacial lakes are easily identifiable in RES data as the bright flat specular reflections from an ice–water interface are distinct from the rough variable power

Recent advances in the understanding of the geology

In October 1993 the Yorkshire Geological Society held a full-day meeting with the title 'Advances in west Cumbrian geology resulting from the Nirex investigations around Sellafield' (Holliday Rees 1994) The meeting presented results from the then ongoing geoscience investigations by United Kingdom Nirex Limited (Nirex) into whether the Sellafield area in west Cumbria could be
