CONSIDERATIONS ON THE MERCURY VAPOUR ANALYSIS
IN PROSPECTING BARYTINE DEPOSITS
(Abstract)
The paper presents the main results obtained by experimenting the mercury
vapour method in prospecting barytine mineralizations in the Romanian East
Carpathians. It mainly deals with problems concerning the influence of different
physical-geological factors on measurements (temperature and time of sample
heating, their content of barytine and associated complex sulphides, etc.),
with implications in establishing possibilities and application limits of this
method.
The maximum mercurometric anomalies (up to 400 mV) were obtained in the presence
of barytine associated with sulphides. A good correlation between mercurometric
anomalies and those of induced polarisation can be noticed as well.
Key words: mercurometry, prospection, barytine, complex sulphides, induced
polarisation, resistivity.
