1. Seismic Micro Zonation (SMZ)
• Classification of Mineral Deposits on the basis of Mode of Occurrence
structural feature and Forms.
• There we have 3 Kinds of Deposits.
i. Surface Deposits.
ii. Crustified Deposits.
iii. Stratified Deposits.
2. Metal concentration in ore forming
hydrothermal solutions
Skarn 740-7700 ppm
Porphyry 80-4600
Mississippi valley 200-10900
Vein 3.5-2200
Massive Sulphide 50-62
Vein Very less fraction
Low concentration ppm
3. Bessi Deposits (tapar)
• Individual Deposits Commonly contain 0.1 to 10 Million tonnes of ore
combined grades Cu+Zn+Pb Grades of 300C
• The most imporatn requirement of the volcano Associated form of
ore deposits are penecontemporaneous volcanism; must have
accompanied Hu formation of deposits.
