Opis:
Basic statutory task of the Polish Geological Institute-National Research Institute within the framework of the State Geological Survey is conducting detailed geological mapping ofPoland. One of the leading themes of the III Polish Geological Congress is the "Geological mapping - history and contemporary challenges”. The article presents an analysis of the current state ofdetailed geological mapping in the Sudetes and adjacent areas, as well as the reasons for the need to start a new, second edition of the Detailed Geological Map of the Sudetes (SMGS) at the scale of 1 : 25,000. These reasons can be briefly defined as follows: long-lasting duration of the SMGS development (nearly half a century), lack of uniformity, and outdatedness of this edition. The first edition covered 139 map sheets at the scale of1 : 25,000, with a total area over 10,100 km2. The newly presented comprehensive project assumes very fast workflow, just 10 years of work before the implementation of the second edition of the 1 : 25,000 SMGS. The new edition is going to be more modern and based on the new classification of rocks, providing more information about their origins, geotectonic settings, as well as the processes and geological phenomena, which are not included in the first edition of the 1 : 25,000 SMGS.

Opis:
Throughout SW Fennoscandia, numerous approximately W-E trending faults and ductile shear zones have recently been recognized. The regiona--scale zone of strike-slip displacements [Mazury lineament] with a dextral component was referred by many authors as apparently influenced by the distribution of ca. 1.6-1.4 Ga old "anorogenic" intrusions of the Mazury Complex [NE Poland]. However, new detailed structural and kinematics studies of drill-cores from 255 boreholes located throughout NE Poland and SW Lithuania [Lazdijai region] indicate that the Mazury Complex, the Suwałki Anorthosite Massif and surrounding lithotectonic domains share a common ductile thrusting deformation, calling into question the concept of a large-scale dextral shear zone and also the "anorogenic" origin hypothesis of the Mazury Complex. One important advance has been the accumulation of structural and kinematics information that allows assessment of the main orogenic transport direction commonly towards the SW, locally to the NE [e.g., in the eastern part of the Suwałki Anorthosite Massif]. This assessment has been coupled with the recognition of the role of major and numerous ductile shear zones within the western part of the East European Platform. In general, compressional deformation with ductile thrusting predominated in the western part of the East European Platform. Very probable strike of regional mylonitic foliation [S1] from almost 100 boreholes has been established, based on geophysical measurements of the curvature of borehole axis and a few tens oriented core samples [SW Lithuania]. It is assumed that the crystalline rocks of NE Poland and SW Lithuania [Lazdijai region] were subjected to similar ductile thrusting to transpressional deformation during the late Gothian [or newly defined Dano-Polonian] orogeny [ca. 1.5 Ga].
