Summary:

This book shows the results of structural, compositional and evolutionary investigations of the Precambrian crust of the East European Craton in Lithuania and adjacent areas. This work contributes to the recognition of the platform basement, which remains weekly investigated worldwide, despite it encompassing the surfaces of cratons. It presents a methodological example of systematic studies of the covered platform basement, integrating petrological, geochemical, isotopic, and geophysical methods, as well as geological mapping, in order to present comprehensive geological picture of the subject matter. In a systematic and summarized form, factual data and intellectual material acquired by researchers are combined. Important papers and industrial reports (also written in Russian and Lithuanian) make this information accessible for both local and international scientists and practitioners and stimulate the advertising, application, and augmentation of this knowledge
