The book is designed to give a comprehensive up-to-date picture of the applications of seismology. 11.15.6.2 Land-Based Seismic Methods in Mineral Exploration. Reflection seismology (or seismic reflection) is a method of exploration geophysics that uses the principles of seismology to estimate the properties of the Earth's subsurface from reflected seismic waves.The method requires a controlled seismic source of energy, such as dynamite or Tovex blast, a specialized air gun or a seismic vibrator, commonly known by the trademark name Vibroseis. Examples include salt diapirs, overthrust and folded belts, major unconformities, reefs, and deltaic sands. Seismic exploration (reflection and refraction) 2. Historically, seismic exploration would leave cleared lines in the forest up to eight metres wide for lengths that could stretch many kilometres.
