Fotolineamenty i ich znaczenie w geologii
Abstract
PHOTOLINEAMENTS AND THEIR GEOLOGICAL SIGNIFICANCE
Summary
The possibilities of interpretation in photogeology markedly increased along with launching artificial satellites of the Earth. Satellite photos facilitated discovery of numerous various deposits and made possible more rapid and less expensive drawing of geological maps in the scales from l : 200 000 to l : l 000 000, especially for areas unknown from the geological viewpoint or hardly accessible. In Europe, the most important is interpretation of photolineaments related to geological-structural elements, which is illustrated with several examples from Italy, the Netherlands, Poland, FRG and GDR.
Similarly as in other countries, we are comparing results of interpretation of satellite photos with geological structure of best known areas. The comparisons show a remarkable coincidence of photolineaments and tectonic elements. It follows that the photolineaments may be used in geology in:
- looking for structural elements,
- tracing extensions of evidenced structural elements,
- stating consistency of geophysical and photogeological interpretation,
- looking for clearly marked, repeated directional trends displayed by various photos (photos made using various techniques or in various seasons).
Other lineaments represent supplementary material which may be used in simultaneous reinterpretation of all the data (geophysical and borehole data) and making projects of detailed prospecting. The latter is especially the case of areas characterized by increased concentration of photolineaments and their criss-crossing and crossing with circular or ovate structures.
