Abstract
The paper presents a particular form of soil instability, which is rarely observed in Slovenia. This is a lateral spread of the soil, which appeared some years ago in the central part of Dolina area in the municipality of Puconci. The area is mainly build up from clay and sandy Sediments of the Pannonian Sea, predominantly Pliocene age. A significant damage of building has begun several years ago. According to data from research carried out, we suggest that the flat area is disintegrated into individual blocks, moving in different directions. These led to such extensive damage to buildings. Possible cause could be erosion of Dolinski stream at the eastern edge of the area or seismic survey (blasting, vibrations), which were carried out here about 20 years ago. Determination the exact cause of the formation of the soil lateral spread, its extent and dynamics, remain a challenge for the future.

V okviru pilotnega projekta ocenjevanja plazljivosti, ki ga je v letih 2011 in 2012 Geolo{ki zavod s podizvajalci izvajal za Ministrstvo za kmetijstvo in okolje je bila v preglednem merilu, namenjenem uporabi na nivoju ob~in, obdelana tudi ob~ina Puconci
Po Pleni~arju (1970) gre za sedimente, ki so za razliko od svoje podlage popolnoma brez fosilov, zaradi ~esar je njihova natan~nej{a stratigrafska opredelitev problemati~na
Summary
The paper presents a particular form of soil instability, which is rarely observed in Slovenia. Za Gori~ko je zna~ilno menjavanje gri~evja in vmesnih ravnin, pri ~emer nadmorske vi{ine redko presežejo 400 m (Bavec et al, 2012). Opisani litolo{ki razli~ki med seboj niso lo~eni zaradi premajhne debeline posameznih plasti in pokritosti terena. Bo~no raz{irjanje tal v osrednjem delu Doline
