Sedimentology of the late cretaceous and early tertiary (tuffaceous) chalk of Northwest Europe [PDF]

, 1994
The Tuffaceous Chalk of South Limburg (The Netherlands), a friable, porous, bioclastic carbonate sandstone, became subject of scientific interest in 1770, when workers found a large skull of Mososourus comperi in the subterranean quarry of Mount St ...

Application of 9-component S-wave 3D seismic data to study sedimentary facies and reservoirs in a biogas-bearing area: A case study on the Pleistocene Qigequan Formation in Taidong area, Sanhu Depression, Qaidam Basin, NW China

Petroleum Exploration and Development
To solve the problems in restoring sedimentary facies and predicting reservoirs in loose gas-bearing sediment, based on seismic sedimentologic analysis of the first 9-component S-wave 3D seismic dataset of China, a fourth-order isochronous stratigraphic ...

Sedimentology and preservation of aeolian sediments on steep terrains: Incipient sand ramps on the Atacama coast (northern Chile) [PDF]

, 2017
The origin of topographically controlled aeolian landforms in high-relief settings is difficult to synthesize under general models, given the dependence of such accumulations on local morphology.

Seismic Sedimentology for the Characterization of Quaternary Evaporite Facies in Biogas-Bearing Taidong Area, Sanhu Depression, Qaidam Basin, NW China

Applied Sciences
S-wave seismic data are unaffected by natural gas trapped in strata, making them a valuable tool to study evaporite facies comparing to P-wave data. S-wave seismic data were utilized to construct an isochronous framework and analyze evaporite facies by ...

Borehole seismic methods for opencast coal exploration [PDF]

, 1990
Surface seismic techniques lack the resolution to image the top 100m or so of the earth's surface necessary for opencast coal exploration. The work reported in this thesis is the development of borehole seismic methods making use of the closely spaced ...
