selves should have spherical forms; the projection of them 
on the surface being circular. Their sites are not  "an- 
chored" to a single spot; they may wander /thus showing e. 
ge the "shifting" circles of the depression around the Lake 
Fertó, 8 in Fig.6./. 
Another explication could be: the circular linears are the 
"palimpsest" traces of craters caused by asteroid-impacts. 
This possibility is of course restricted to those features, 
which can not be explained by other means /e.g. the shape 
of the Mátra mountain reflects the original caldera of the 
volcano which brought about the rocks of it, and collapsed 
along concentric ringsA 
CONCLUSIONS 
The environment of subsurface water is very complicated — 
sophisticated, The boundaries of human activity under the 
earths surface became very deep and are still in expansion. 
In order to understand the hydrogeological effects and to 
collect data about the destruction and pollution of the 
waterhousehold respectively the aquifers: all means offered 
by wp-to-date techniques have to used. 
Aerospace methods /combined with the interpretation of 
other data/ offer indispensable means for the investigation 
of the deepest parts of the crust, New results may be a- 
chieved — as it was the case with the Carpathian Basin; the 
"face" of which was completely transformed — showing for 
the first time features, facts and aspects never hoped, or 
suspected before. 
It is obvious, that all these new results will have beyond 
hydrogeological consequences an impact also in ore-, oil 
and gas-prospection — to mention but a few.
