    Consequences of induced polarization in magneto telluric

    Summary. Both in situ and laboratory studies indicate that naturally occurring earth materials are electrically dispersive. A review of both historical and recent developments in the field of dispersion is presented, including induced polarization (IP) as used in mineral prospecting.

    Preliminary Model of Porphyry Copper Deposits USGS

    The median size of the longest axis of alteration surrounding a porphyry copper deposit is 45 km, while the median size area of alteration is 78 km2 (table 2). Vertical Extent. The vertical extent of ore is dependent upon the lower copper cutoff grade, which will vary with the price of copper
