W zachodnich Karpatach fliszowych na obszarze pomiędzy Żywcem i Suchą Beskidzką strefa Siar stanowi zewnętrzny fragment płaszczowiny magurskiej i nasuwa się na jednostkę przedmagurską i płaszczowinę śląską. Szczegółowe zdjęcie geologiczne okolic Mutnego uwzględniło nową interpretację strukturalną, z drugiej strony profil litostratygraficzny obszaru badań został skorygowany. Strefa Siar jest reprezentowanatu przez: warstwy inoceramowe (senon-paleocen), piaskowce z Mutnego (paleocen), pstre łupki formacji z Łabowej (eocen środkowy), warstwy hieroglifowe (środkowy-górny eocen), warstwy podmagurskie (środkowy eocen-dolny oligocen?), piaskowce magurskie w facji glaukonitowej (górny eocen-oligocen) oraz warstwy nadmagurskie (oligocen). Utwory te w płaszczowinie magurskiej w badanym terenie tworzą łuski Pewli Wielkiej, Mutnego i Pewli Małej. Badania wykazały iż w warstwach inoceramowych i w piaskowcach z Mutnego występują klasty szarych margli. Tworzenie się tych klastów związane jest przypuszczalnie z aktywnością tektoniczną południowego skłonu kordyliery Raczy.

In the western part of the Flysch Carpathians, in the area between Żywiec and Sucha Beskidzka, the Siary Zone (outer part of the Magura nappe) overthrusts the Fore-Magura Unit and the Silesian nappe. The results of detailed mapping done in the Mutne area allows for a new structural interpretation, and also correction of lithostratigraphic profile of the study region. The Siary Zone includes: Inoceramian beds (Senonian-Paleocene), Mutne sandstones (Paleocene), variegated shales of the Łabowa Formation (fin.) (lower and middle Eocene), hieroglyphic beds (middle and upper Eocene), the Sub-Magura beds (middle Eocene-lower Oligocene?), Magura glauconite sandstones (upper Eocene-Oligocene), andSupra-Magura beds (Oligocene). In the study area, these strata form the Pewel Wielka, the Mutne and the Pewel Mala slices of the Magura nappe. The studies also show that the Inoceramian beds and the Mutne sandstones encompass clasts of gray marls whose formation seems to have been linked to the tectonic activity of southern rise of the Racza Cordillere.

This paper is a preliminary report on using the Digital Elevation Model (DEM) and Shaded Relief Image in geological mapping in the Carpathians. Digital processing of the topographical maps in 1:25 000 scale enabled 3D visualization of a fragment of olish Outer Carpathians, situated between Dobczyce and Mszana Dolna villages. This permitted a preliminary interpretation of lin - eaments occurring in the study area and recognition of correlation between the lineaments and geological structure of the Carpathians Flysch Units. The picture of the Shaded Relief Image was compared with existing remote sensing data such as radar and satellite images, and with results of geological mapping carried out by author in the field. The recognized lineaments can reflect fault zones in the flysch cover and in the consolidated basement. The correlation of lineaments detected in the digital models with discontinuities confirmed in outcrops demonstrates the value of digital methods in geological cartography.

The Mutne Sandstone Member occurs within the Jaworzynka Formation of the Magura Nappe depo- sits, typical for the western marginal Siary subunit. In the area north of Jeleśnia it is represented by the thick sand- stone complex. Typical and complete profile of this division is located in Mutne village next to Jeleśnia, on the slope of Janikowa Grapa Mt. This locality represents the type section for the Mutne Sandstone Member, while three others: Jaworzynka, Rychwałdek and Kuków-Rzyczki serve as reference sections. The age of the Mutne Sandstone Member was determined as Maastrichtian-Palaeocene; but only Maastrichtian is documented by foraminiferal assemblages. The Palaeocene age comes however from the superposition of this lithosom within the Magura Nappe profile. The Campanian/Maastrichtian-Palaeocene complex of Siary Subunit deposits provides the perfect example for application of supersequences to the Western Flysch Carpathian basin. It fits the Upper Zuni IV supersequence and global time slice. The Mutne type locality is also a prime geotourist attraction and object of inanimated nature proposed for protection.

A hitherto unknown trace fossil was found in some abundance in turbidites of the Polish Outer Carpathians. The occurrence is within the Hieroglyphic Beds of the Silesian Nappe, within the Szczyrzyc Synclinorium, of Middle Eocene age. The trace fossil is a wide, J-shaped structure having a narrow, upward tapering shaft as a connection to the seafloor. The distal end also tapers, to a blind termination. The burrow lumen is surrounded by an irregular spreite structure. The trace fossil is compared with the work of burrowing holothurians, which show some comparative features that suggest a tracemaker belonging to the Apodida.
