Infrasonic Signal

A comprehensive analysis of waveforms of seismic and infrasonic vibrations from the earthquake that occurred on December 5, 2014, in the water area of Lake Hovsgol was performed. The analysis showed that the infrasonic signal recorded at the Tory station (Geophysical Observatory of the Institute of Solar-Terrestrial Physics, Russian Academy of Sciences) was formed by the sources of three generation types: local, secondary, and epicentral. The obtained results allow us to propose the model of epicentral infrasonic signal generation by flexural waves from an elastic ice membrane on the surface of Lake Hovsgol.

First Occurrence

The genus Stylatractus Haeckel, 1887 (Radiolaria, Actinommidae) is abundant in upper Pleistocene – Holocene sediments form the Rio Grande do Sul continental margin. Some species of this genus are important Cenozoic biostratigraphic tools. A detailed analysis of the species distribution in Core T18 (GEOMAR VII), as well as an estimate of the chronology of these sediments was done. A revision of Stylatractus is proposed, based on the growth patterns of the Actinommidae skeletons. Three species of Stylatratus were identified in the studied material: Stylatractus neptunus Haeckel, emend., Stylatractus pluto Haeckel n. comb. and Stylatractus nerinus n.sp. The occurrence of Stylatractus nerinus n.sp. suggests that these sediments were deposited in the upper Pleistocene. The Pleistocene-Holocene transition is established by the first occurrence of Stylatractus pluto Haeckel n. comb. The results obtained from Core T18 can be extended to other cores from the Rio Grande do Sul continental margin where the genus was reported.

Detailed single-channel seismic reflection survey has been carried out in the Lakonikos Gulf, Southern Péloponnèse, aiming to a better understanding of the neotectonic structure of the Lakonikos Basin. Our survey showed that, contrary to the model of a simple N-S asymmetric graben previously considered, a tectonic horst occurs within the tectonic graben of Lakonikos. A subsidence of more than 1000m is produced by the N-S marginal faults, whereas, the N-S faults creating the central horst structure within the Lakonikos graben are high-angle reverse faults, which have uplifted the sea bottom together with the Pleistocene and Holocene sediments by about 100m. Several E-W vertical transcurrent faults, with strike-slip motion deform the N-S structures. The central tectonic horst structure is very recent as the observed deformation of the Upper Pleistocene and Holocene sediments indicated and a transtensional geodynamic regime is suggested.

Set Up

The radiocarbon dating laboratory was set up during 1972 and 1973 with financial support of the FKFO (Fonds voor Kollektief Fundamenteel Onderzoek) Belgium, to enable us to place Upper Pleistocene and Holocene sediments in their correct stratigraphic position. Dating of samples began in the middle of 1974.
