Neotectonic structures of different ranks--elevations and depressions, lineaments and GDAZ (geodynamic active zones) are presented on the map. Geodynamic active zones are linear or isometric crust volumes of different scales that localized spatially, where conditions for tectonic stress concentration and relaxation, and high gradients of movements and rocks deformity are favorable by different reasons. They differ from active faults, which are rare on geodynamic-stable platform territories, by absence of noticeable displacements in rocks and a more geodynamic stability. Nevertheless, GDAZ can be hazard to engineering buildings, since these zones are favorable for developing exogenous (such as erosion, impoundment, karst, sliding, etc.) and endogenous geological processes (such as seismicity, water-fluid permeability and heat flux). They can also become migration and localization channels of nature-anthropogenic pollution.展开更多
文摘This paper describes principles, methods and results of a large-scale (1: 25,000) structural-geodynamic mapping of Moscow territory. Neotectonic structures of different ranks--elevations and depressions, lineaments and GDAZ (geodynamic active zones) are presented on the map.
