Methodological development and tests were carried out in the Savukoski-Pelkosenniemi area and eastern Rovaniemi during the project ‘Novel technologies for greenfield exploration’ funded by Tekes. The aims were to develop or provide recommendations for suitable drilling equipments and methods that would enable the sampling of both basal till and bedrock at the same time, as well as stratigraphic...

Fossil specimens of the exclusively oceanic calcareous nannoplankton were found only in the upper 200 m of the Cape Roberts Project 3 (CRP-3) cores. These assemblages are depauperate and sporadic in occurrence. The majority of the assemblages contain fewer than 4 species, indicating a severe palaeoecological restriction. The clear domination of these assemblages by reticulofenestrid species, co...

Dynamics in the rate of compositional change (rate-of-change; RoC), preserved paleoecological sequences, are thought to reflect changes due exogenous (climate and human forcing) or endogenous (local dynamics biotic interactions) drivers. However, sedimentation rates sampling strategies can result an uneven distribution time intervals known affect RoC estimates. Furthermore, there has been relat...

In this paper a new mathematical procedure is presented for combining different pieces of evidence which are represented in the interval form to reflect our knowledge about the truth of a hypothesis. Evidences may be correlated to each other (dependent evidences) or conflicting in supports (conflicting evidences). First, assuming independent evidences, we propose a methodology to construct comb...

A seismic volume of a certain stratigraphic layer may be decomposed into components for channel analysis. In the first case study of stratigraphic interpretation, the relative amplitude of the first component outlines the channel. The relative amplitude of the second component discovers different lithological or stratigraphical features inside the channel. The relative amplitude of the third co...

A new trace fossil, Koptichnus rasmussenae, was recently reported from the Cretaceous of Denmark. This burrow is thickly lined with cuboids that tracemaker cut siliceous sponges. newly discovered specimen lower Selandian Kerteminde Marl, found in a loose boulder Gundstrup gravel pit (Fyn, Denmark), extends stratigraphical range this ichnotaxon previously known Coniacian to middle Paleocene and ...
