Books published during recent years in the field of applied geo- physics
can be, in general, divided into two main types. The first type covers
such multiaspect books as "Introduction to Geophysics", while the
second-special works on fundamental theoretical prob- lems with an
elaborate mathematical description. The books of the first type are
mainly intended for beginner students and specialists in adjacent
fields. The books of the second type may be useful for teachers and
theorists. However, there are also books of another (third) type. These
books describe the experience in geophysical in- vestigation under
specific conditions or propose solutions to concrete geological
problems, being a methodological guide for geophysicists and
concentrating ideas both for advanced students and researchers. Authors
hope to give the readers a book of this kind. Interpretation of
geophysical fields is a complex consistent pro- cess. Its successful
realization requires: (a) knowledge of geological regularities and
geological situation; (b) availability of petrophysical support; (c)
mathematical methods of solving direct and inverse problems of
geophysics (i.e. computation of geophysical fields from a known source
and determination of source characteristics from known fields); (d)
application of statistical and logico-informational procedures to the
analysis and synthesis of observation results for revealing desired
objects and peculiarities of the geological structure.
