Shallow subsurface layer anomalies at the Királyhágó square in Budapest

Abstract

During an everyday engineering geological field study (Budapest, Buda Mts) an extraordinary
sedimentary sequence was discovered. Instead of in situ Tard and Kiscell Clay Formations, a 14 m-thick
Quaternary slope deposit was exposed consisiting of reworked matériái of the above formations. The
inverted sequence of the reworked matériái and the extremely thick valley-infill refers to slope processes
have taken place more complicated indicate than it was once belived.
