Zdjęcia satelitarne jako źródło informacji pośredniej o wgłębnych strukturach geologicznych
Abstract
SATELLITE PHOTOS AS A SOURCE OF INDIRECT INFORMATION ON DEEP-SEATED GEOLOGICAL STRUCTURES
Summary
Photolineaments interpreted in satellite photos of the area of Poland are characterized by fairly regular orientation. Directions predominating here include ENE-WSW (60- 800) and NW-SE (120-140°) whilst the direction NE-SW (30-40°) appears most common among subordinate ones. It follows that the network of photolineaments (plotted in the scale 1 : 1,000,000) is essentially superior in relation to major tectonic units of Poland. In tum, the photolineaments appear related to diagonal planetary system of NW-SE and NE-SW oriented fractures. The map of frequency of photolineaments, enclosed here, illustrates some conclusions concerning dependence of frequency and course of isolines on depth of occurrence and tectonic involment of the basement. Attention is also paid to readability of the margin of the East-European Platform in satellite photos. Although it is very difficult to interpret any of satellite lineaments as direct reflection of this zone, it may be assumed that several photolineaments arranged along the platform margin represent its reflection in overlaying strata. This view is further supported by marked influence of the platform margin on distribution of photolineament concentrations and course of their isolines.
