examination. The main role in the proposed algorithm plays a 
notion “information value”. Unfortunately, from the author’s 
experience follows that majority of geophysicists and 
archaeologists have troubles with accepting this approach. 
Objects of archaeological study occur at a small depth and, 
consequently, the distance Ax between profile observation 
points usually varies from 20 cm to one meter. Distance Ay 
between profiles may not exceed Ax by more than three times 
and ideally Ay must equal to Ax. Selection of a magnetic sensor 
level (practically it ranges in interval of 0.1 - 3 meters) depends 
on the concrete archaeological/geological situation. 
interpretation at archaeological sites (after Khesin et al., 1996, 
with modifications) 
According to our experience [Eppelbaum and Khesin, 2001; 
Eppelbaum et al., 2000a,2000b,2001,2003a] the general scheme 
of geophysical data processing and interpretation at 
archaeological sites may be composed using the following 
procedures presented in flow-chart (Figure 1).

2. BRIEF DESCRIPTION OF THE EMMAUS- 
NICOPOLIS ARCHAEOLOGICAL SITE 
Christian archaeological site Emmaus-Nicopolis is well known 
in the ancient and Biblical history. The site (its fragment is 
shown in Figure 2) located halfway between Jerusalem and Tel 
Aviv, first built in the 5th century, over the site believed to be 
the place where Jesus appeared to two of his disciples after his 
resurrection. The Crusaders rebuilt it on a smaller scale in the 
12th century (Mayer, 1996). Nicopolis is assumed in almost all 
Christian Pilgrim texts from the 4th century onward. In 221 
C.E. the Emperor Elagabalus gave Emmaus the title of city and 
the name Nicopolis. 
The primary aim of magnetic investigations at this site was 
detecting underground tunnels (caves) partially investigated at 
the eastern part of the area. However, purpose of our 
investigations was suddenly changed during the field 
exploration.
