How does an unconformity affect our geological knowledge of an area?

UNCONFORMITIES ARE THE RECORD OF MAJOR EPISODES OF UPLIFT, EROSION AND SUBSIDENCE DURING THE GROWTH OF THE CONTINENTS AS EARTH HISTORY PROGRESSED. THEY ARE THEREFORE IMPORTANT EVIDENCE FOR CRUSTAL MOBILITY THROUGHOUT EARTH HISTORY.
