This book focuses on the experimental determination of the physical properties of silicate melts and magmas close to glass transition. Abundant new data are presented. The same type of measurement is performed on a range of melts to test the effect of composition on physical properties; and a range of different techniques are used to determine the same physical properties to illustrate the relationships between the relaxation of the melt structure and the relaxation of its physical properties. This book is of interest to experimental researchers in the discussion of data obtained from both a materials science and a geoscientific point of view.

This proceedings book investigates the possibilities for creating new models of the continental lithosphere structure by integrating methods from geothermodynamics and deep geoelectrics. It particularly focuses on the use of powerful controlled sources of electromagnetic field to study the nature of deep geophysical boundaries. It also presents research related to the transition boundary between the brittle and quasiplastic states of Earth’s crust matter and the position of creep areas in Earth’s crust, as well as geothermal and rheological studies in combination with the deep electromagnetic soundings – a promising direction that allows the tectonophysical reconstruction of natural stresses in the lithosphere. The experimental study results and tectonophysical modeling are discussed in the context of the Fennoscandinavian shield, the Indian Craton, the Himalayas, Eastern Tibet and the Eurasian continent as a whole. The book appeals to researchers interested in solid Earth physics.

An introduction to geomagnetic storms and the hazards they pose at the Earth’s surface Geomagnetic storms are a type of space weather event that can create Geomagnetically Induced Currents (GICs) which, once they reach Earth’s surface, can interfere with power grids and transport infrastructure. Understanding the characteristics and impacts of GICs requires scientific insights from solar physics, magnetospheric physics, aeronomy, and ionospheric physics, as well as geophysics and power engineering. Geomagnetically Induced Currents from the Sun to the Power Grid is a practical introduction for researchers and practitioners that provides tools and techniques from across these disciplines. Volume highlights include: Analysis of causes of geomagnetic storms that create GICs Data and methods used to analyze and forecast GIC hazard GIC impacts on the infrastructure of the bulk power system Analysis techniques used in different areas of GIC research New methods to validate and predict GICs in transmission systems
