Abstract: The necessity of fine geology study is put forward in this paper through requirements analysis of economic development, resource exploration, environmental protection and development of geosciences. The concept and technical system of fine geology are illustrated. Fine geology involves precise and detailed study of geological phenomena based on advanced technology and high sensitivity of the measuring instrument; results obtained from such study can be used for the advancement of scientific research, exploration and economic construction. The technical system of fine geology include remote sensing, geophysical prospecting, geochemical exploration, drilling, isotopic dating, space positioning techniques and computer technology, etc, and an integrated full range airsurfacesubsurface 3dimensional survey usually completes the fine geology study. Taking remote sensing as an example, the feasibility of fine geology is described through analyses of the development and application of geophysics, remote sensing, isotope and geochemistry in fine geology studies at home and abroad. The prospects of applying fine geology in mineral resource exploration, geological research, environmental protection, national defense and geological disaster investigation are discussed in this paper.
