heal.abstract | Η εργασία αυτή πραγματοποιήθηκε στα πλαίσια του προγράμματος σπουδών του Τμήματος Σ.Ε.Μ.Φ.Ε. του Ε.Μ.Π. για το υποχρεωτικό μάθημα της διπλωματικής εργασίας. Σκοποί της διπλωματικής εργασίας είναι: α) η επισκόπηση των κυριότερων επιστημονικών ερευνών που έχουν πραγματοποιηθεί τις τελευταίες δεκαετίες σε σχέση με την σύσταση, την δομή αλλά και τις διεργασίες που συντελούνται στον μανδύα αλλά και πως αυτές επηρεάζουν τα υπόλοιπα στρώματα της Γης. β) η παρουσίαση των άμεσων αλλά και των έμμεσων μεθόδων κατανόησης και ερμηνείας της φύσεως των διεργασιών του μανδύα, καθώς και των σύγχρονων μεθόδων εξερεύνησης του που εφαρμόζονται στις μέρες μας. | el |
heal.abstract | This thesis was carried out within the curriculum of the School of Applied Mathematical and Physical Sciences of the NTUA. The aim of this diploma thesis is to review the scientific research area covered over the last years in relation to the composition, structure and processes involved in the Earth’s interior presenting both direct and indirect methods of understanding and interpretation of the Earth’s interior. This includes its nature, its parts (crust, mantle and core), the processes taking place there and the relevant modern methods of exploration. The combination of synchrotron x-ray facilities with high-pressure methods provided new experimental tools for addressing geophysical problems relevant to understanding the interior of the Earth and other planets. Well established high-pressure synchrotron methods applied to the diamond anvil cell but also to large-volume apparatus. Synchrotron capabilities have been improved by new innovations, such as high-pressure technology, X-ray diffraction techniques applied with numerous improvements resulting to extended pressure – temperature range coverage and better ability to recover information from crystallographic data. Among the important geophysical questions related to the Earth’s silicate mantle are the origin of seismic discontinuities in the upper mantle, the rheological properties of mantle minerals and their influence on dynamic flowing within the Earth and on the properties of the core–mantle boundary region. In the case of the Earth’s core, key questions are centred on the identity of the light elements of the core and their effect on energetics and thermodynamics, the melting curve of iron and its alloys and the origin of seismic anisotropy in the inner core. All above methods are applied using the essential equations of Elasticity theory. The elastic behaviour of minerals is central to our understanding of the structure and properties of the Earth, and other planets. There have been many new developments in the experimental methods used to determine the elastic properties of minerals. The precision and accuracy of the experimental results have been significantly improved in recent years. Taking into account the aforementioned advances in measurement techniques, the physical principles in conjunction with the capabilities of the experimental techniques for the exploration of Earth’s interior are being reviewed. | en |
