Detecting thin layer by using different seismic geophones and special processing technique at an archaeological site in Southeastern China

Геофизический журнал, 2015
The properties of geophones are important factors for high-resolution seismic exploration and have great influence on data quality. In this study we will address the problems of ultra-shallow seismic data acquisition and processing.

Submarine Stratigraphy of the Eastern Bay of Naples: New Seismo-Stratigraphic Data and Implications for the Somma-Vesuvius and Campi Flegrei Volcanic Activity

Journal of Marine Science and Engineering, 2022
The submarine stratigraphy of the eastern Bay of Naples is studied through seismo-stratigraphic data correlated with borehole data. Multichannel seismic profiles are interpreted in order to reconstruct the stratigraphic relationships between the ...

Characterization of a Pre-Trajan wall by integrated geophysical methods [PDF]

, 2015
The purpose of this study was to characterize a pre-Trajan mosaic-decorated wall structure located beneath the Cryptoporticus of the 'Baths of Trajan' complex in Rome. The surveyed wall is 15m long, 0.9m wide and 3 to 5m high.

Transpressional uplift of Wensu Uplift in northern Tarim Basin, NW China: evidence from seismic profiles

Shiyou shiyan dizhi, 2020
The Wensu Uplift is an important structural belt in the northern Tarim Basin, NW China, always regarded as a thrust belt. However, this recognition is not only incompatible with the facts that synthetic and antithetic faults are equally developed in ...
