Synthesis of geological and airborne geophysical data for prognosticating new area for the exploration of lead and zinc in Sindesar Khurd area,Rajpura-Dariba belt,Rajsamand district,Rajasthan

In the Rajpura-Dariba belt zinc and lead mineralization was established on the basis of gossan and opinions were given that the deposits are stratiform and syngenetic. During last two decades metamorphism and volcanic processes have been attributed for the generation of exhalative and remobilized lead-zinc ore bodies. Subsequent exploration was based on the concept of successive borehole planning around positive intersections. Areas having surface indications of base metal mineralization and their extensions have been already explored. Recent deep drilling by Hindustan Zinc Limited (HZL) in this area has intersected rich ore lodes, thereby confirming depth ward continuity of ore zones at some places. It indicates possibility of searching hidden deposits by innovative techniques. Therefore, today, there is a challenge before geoscientists to discover new deposits in this area by an exploration technique which should have low risk, consume less time and it should be cost effective.
