Abstract
The study area, Outokumpu, is a hard rock area and it is well known for its unconventional Precambrian massive Cu-Co-Zn sulphide deposits (~1.97 Ga) which were discovered in 1910. This study was conducted to understand the seismic reflection characteristic in hard rock environment in Outokumpu, Finland. The geophysical techniques involved data processing for two 2D surface seismic lines and a vertical seismic profiling data, generating synthetic seismogram, and joint interpretation of seismic reflection. Due to the complex physical properties in hard rock area, special attention paid in data processing includes the definition of geometries, preserving the high-frequency information, noise suppression and deconvolution. These efforts provided high resolution seismic results. The subsurface structure of Outokumpu-type assemblage is observed. Moreover, there is a remarkable consistency between seismic surface results and the VSP result.
