Near-surface structure of the Carpathian Foredeep Marginal Zone in the Roztocze Hills area
Shallow seismic survey was made along 1280 m profile in the marginal zone of the Carpathian Foredeep. Measurements performed with standalone wireless stations and especially designed accelerated weight drop system resulted ...
Characterization of drilling-related noise and curvelet-based evaluation of seismic-interferometric reflections for imaging of iron-bearing formations in Pilbara,Western Australia
Here we analyse ambient noise (AN) data generated during drilling of exploration boreholes and recorded using a dense array deployed over one of the numerous shallow iron-ore mineralisation targets in the Pilbara region ...
Structure of a diffuse suture between Fennoscandia and Sarmatia in SE Poland based on interpretation of regional reflection seismic profiles supported by unsupervised clustering
The Paleoproterozoic suture between Sarmatia and Fennoscandia (SFS), two major components of the East European Craton, extends SW-ward from Russia through Belarus to SE Poland. The exact character of this suture remains ...
Anisotropy Estimation of Lower Paleozoic Shales from Northern Poland using Microseismic Data
(Institute of Geophysics, Polish Academy of Sciences, 2021)
Downhole microseismic monitoring is a widely used tool for the assessment of hydraulic fracturing job effectiveness. During the process of fluid injection into the reservoir, new fractures develop due to the induced ...
Variations of permafrost under freezing and thawing conditions in the coastal catchment Fuglebekken (Hornsund, Spitsbergen, Svalbard)
Two seismic field surveys were organized in the Fuglebekken coastal catchment of Hornsund, Spitsbergen, Svalbard, to map frozen and unfrozen ground and assess the spatial and temporal state of the permafrost. Surveys were ...
Dispersive seismic waves in a coal seam around the roadway in the presence of excavation damaged zone
Excavation damaged zone (EDZ) is a fractured rock mass in the vicinity of the roadway. Knowing its elastic properties, such as seismic velocity, is crucial for the safety of underground mining. However, the seismic wavefield's ...
