Wide application is open for techniques based on the 
use of data produced by thermal-imagery or infrared aeri 
al photography by Soviet IR imager "Vulkan" operated from 
airplanes L-qiO, AN—12, AN— Ih-I8, '' Dacota— y", heli 
copter MI-8. 
The technology of copper and 
r a r e-m e t a 1 endogene deposits 
prospecting in arid zones using 
the r m a 1-i mage aerial photogra 
phs allows to reveal ore-magmatic systems promising 
mth respect to local copper and rare-metal mineraliza 
tion of porphyre, pyrite, quartz-vein-greizen formations. 
Contrasting thermal properties of ores and ore-sur 
rounding modifications make the aerial heat-imagery pre 
ferable in relation to other remote control methods of 
search for ore deposits. 'The technology is especially 
efficient for insufficiently-explored regions, as it pro 
vides additional geological information obtainable by 
thermal-image photography only. 'This allows to concentra 
te the ground-based geological and geophysical efforts in 
most promising areas. 
In well-explored regions the data of thermal-image 
aerial photography make it possible to reevaluate the 
prospects of already known fields and minor deposits. 
The technology of reconnai 
ssance and prospecting of salts 
in "dry” lakes using thermal- 
image aerial photographs is a good 
tool for mapping of salts of various compositions, as 
well as salt karst development areas, facilitating ope 
rations in hard-accessible parts of dry lakes and incre 
asing the validity of forecasts concerning possible re 
serves of salts in deposits. 
The technology of explorati 
on of smouldering coal deposits 
using therma 1-i mage photography 
and geothermal methods isa means to 
map zones.of spontaneous fire at levels down to 50 m, 
to determine the depth and direction of fire front ad 
vance, to reveal a network of hidden fissures filled
