Geomorphological features of the lstra morphostructural knot and its delineation using trend analysis

Abstract

The simplest procedures of the trend analysis reveal anomalies in the top and base surfaces and in the depth and density of dissection within the area of the Istra morphostructural knot (western part of the Moscow region). New variant of the knot boundaries is suggested, delineating the area of maximum anomalies. Geomorphological analysis of the territory suggests an interaction between the tectonic elements and the glacial morphogenesis at the southern boundary of the Istra knot dated to the Moscow glacial time (the Middle Pleistocene).
