Abstract
The Hosokura Mine is situated at the eastern margin of so-called "green tuff region" in northeastern Honshu, and is one of the largest lead and zinc producers of fissure-filling vein type in Japan.
On the basis of the following geological features;
1) the location of the Hosokura mine in view of the regional geologic structure, 2) the relationship among the vein system, the areal geologic structure and the gravimetric anomalies, and 3) some characters of mineralization, which are represented by equal grade and equal Zn/Pb ratio contour maps, some hypothetical guides for exploration have been obtained.
They are summarized as follows;
1) the presumed location of a mine that is of fissure-filling vein-type in so-called green tuff region, 2) the presumed plane extent of the Hosokura mine, and 3) the most suitable level for exploration with regard to mineralization.
