Method and device for determining rocks comprised in the earth crust, notably for mineral exploration

摘要

The inventive method comprises the following steps: microlepton radiation from studied objects is visualized by means of photographic printing on a data carrier of a negative containing an exposed image; and anomalies of said image are detected on the data carrier, whereby said anomalies are identified with the objects of interest. Photographic printing is performed through an optical filter representing at least two transparent plates, whereby a layer of the object of interest is placed therebetween. The thickness of the layer of the object of interest is selected in such a way that visible light could pass through the optical filter.
