Piezoelectric Mineral Mapping Instrument

The Piezoelectric Method (PEM) is based on the detection of a physical parameter of the rock: its piezo-activity - the ability of the media to return an electro-magnetic signal when mechanically stressed.

The ability of piezo active minerals - which are associated with valuable commercial deposits such as gold, tin, tungsten, molybdenum, zinc and mica - to transform seismic waves into detectable electro-magnetic signals makes them the main targets of Piezoelectric prospecting method. A portable, lightweight piezoelectric detector - the MORION 2001 - to be used in the mapping of underground mineral resources, has been developed .
The MORION 2001 is effective in detecting deposits in mineral-bearing rocks with high piezoelectric activity.

Minerals which demonstrate high piezo-activity include:

* Quartz * Tourmaline * Sphalerite * Nepheline * Pegmatite * Apatite-nepheline and Galena-Sphalerite
The MORION 2001's functions are as follows:
Receive, enhance, and register the piezoelectric, electro-kinetic, and seismic signals;
Analyse the kinematic and dynamic characteristics of the signals recorded;
Interpret the data, e.g. pinpoint the piezo-active targets where certain geological formations with special electro-kinetic and seismo-acoustic properties may be located.
