In the field of applied geophysics, the geoelectric methods have been important for about a century, particularly for shallow and near-surface investigations. Geoelectric methods are used extensively to locate buried targets that are conductive and resis• tive in nature. The purpose of active geoelectric surveys is to determine the subsur• face …
Ground Penetrating (or Probing) Radar, more commonly known as GPR, is sirriply one of the most useful geophysical techniques available to engineers and scientists;' It allows us to detect what lies beneath the ground or within buildings. It is primarily a safety aide since it' is used to prevent potentially dangerous situations arising or for the de…
when I first got involved with GPR and its uses in archaeology in the late 1980s, it was a very lonely world, with only a few collaborators with whom I could compare ideas, share data, and work jointly in developing processing and in• terpretation methods. I was fortunate to have had Dean Goodman and Jeff Lucius as friends and collaborators, and…
Central Indonesia consists of an assortment of micro continents amidst micro- oceanic plates. The map in Fig. 2.0-1 is based mainly on interpretation of various authors, checked for accuracy by bathymetric, Bouger gravity, and surface geology maps as well .. Deep sea basins are generally underlain by an oceanic crust. This is supported by …
AN elementary textbook is much concerned with the fundamentals of a subject and these do not change with time. In this respect the second edition of our book •has been little modified. In every other it is much altered for the subject has advanced greatly since we gathered together the material for the original version. The changes have…
Diamonds have inspired dreams of wealth and power throughout history. Until modem times, most diamonds were insignias of royalty and were beyond the reach of the com• mon person, who could only elicit visions of the astounding beauty and wealth brought forth by diamonds. It's no wonder that other gems and precious metals have historically taken a…
There are no documented records of when or how mankind first discovered that a certain
"black rock" would burn. However, it is known that coal was employed as a fuel in China circa
1100 BC and that Welsh Bronze Age cultures had used coal for funeral pyres. There are many other instances where …
During the last few decades coal chemistry and coal petrology have developed as special fields of research, of equal importance from both the scientific and practical viewpoints. Until the nineteen twenties coal chemists used to examine coal as a whole. However, after coal petrographers had. discovered tha…
Application of seismic stratigraphic techniques is nowadays standard practice for interpreting seismic data sets. The advantage of seismic stratigraphy for geological studies lies in the fact that the method combines different scales of observation: large scale remote sensing seismic measurements and the high-resolution well control logging I outcro…
