High-resolution P-and S-wave seismic techniques are used in geological and hydrological mapping in many parts of the world especially where surficial materials or glacial deposits are entirely masking underlying geological units. However, the slow acquisition and sophisticated processing of seismic data are often limiting the wide implantation of the seismic techniques in geological mapping. We are introducing some recommendations to make the use of seismic techniques more efficient for geological mapping. We present a modified seismic land streamer that improves data acquisition rate and allow for surveying larger areas. We also propose implementing the multichannel analysis of surface wave (MASW) as reconnaissance survey prior to seismic reflection surveys. MASW is faster in acquisition and easier in processing. Besides, the S-wave velocity profiles extracted from the MASW data inversion, the data can be displayed in common offset domains to help define areas with complex geology and determine locations of the following seismic reflection surveys. A comparison between results from P-wave and S-wave reflection surveys will be presented to help select the type of seismic survey that will better characterize the near surface geology at the target area. These recommendations are expected to help making the high-resolution seismic techniques more efficient and widely used in geological mapping.
