Experience of the complex application оf geophysical and geoelectrochemical methods for the prediction and prospecting оf mineral deposits

Due to the complexity of prospecting and exploration  of  deep  seated  mineral  deposits, there are new requirements for the methods used. Methods should be  focused on the structural and tectonic characteristics of target objects. A set of methods, including gravity, magnetic, geoelectrochemistry is intoduced. This article describes applying of this complex technology and an example of using it effectively is given.

Structure of superimposed haloes of deep-seated polymetallic deposits (based on example of Аltaiski krai)

Results of field studies run on Zakharovskoie polymetallic deposit (Altaiski Krai) in order to investigate structure of superimposed haloes and to determine velocity of migration of elements forming haloes, are discussed.

Characteristics of 2D- and 3D-potential field anomaly interpretation

This paper contains methods of gravity and magnetic data processing with evaluation of effective density and magnetic intensity of rocks. The most preferred method of 3D-processing so as to create three dimensional models of gravity and magnetic distribution is that one which count gravity and magnetic fields around a circle near the calculation point. It is highly effectively to use this method if there are some isometric objects. This algorithm leads to a geometry distortion of the resulting objects and a marked increase in predicted depth if examined bodies are twodimensional and overlie horizontal or aslope. This might cause errors in data interpretation.

A complex of gravi-, magneto-, electroprospecting аnd geoelectrochemical methods for local prediction and prospecting for hydrocarbon deposits

It is proposed to use interpretational spatial distributions of effective parameters of the medium under investigation instead of measured fields in the process of comprehensive prediction-prospecting investigations. There are used effectively: effective density, effective magnetization, intensity of probable sources of geochemical anomalies.
