The geology of the Zawar lead-zinc mine; a reply

Economic Geology, 1968
Reply is made to several critical discussions published since the publication of the original paper in 1964 (for reference, see this Bibliography Vol. 29, Mookherjee 1; see also Vol. 29, Mookherjee 2; Vol. 30, Poddar 2; Vol. 31, No. 4, 02 E67-02447; Vol. 32, No. 1, 02 E68-00608). The deposit is regarded as a product of ascending hydrothermal solutions.

The data of lead isotope geology related to problems of ore genesis

Economic Geology, 1961
Searching questions about the origins of ore deposits have been asked for many years. Where do ore fluids originate - within the crust, or deeper? Can specific sources of ore metals be identified? When were ores deposited? How long did mineralization continue? What was the rate and paragenesis of deposition?

The geology of the Aguilar lead-zinc mine, Argentina

Economic Geology, 1950
"The Aguilar deposit, in northern Argentina, is a hypothermal lead, zinc, silver replacement in Cambrian calcareous quartzite. The rocks had previously been altered to tactite by a granite stock whose contact is from 150 to 250 m. from the ore bodies.

The geology of the Zawar lead-zinc mine, Rajasthan, India

Economic Geology, 1964
The lead-zinc ores occur in a shear zone in Precambrian metasediments. The shear zone is later than the two recognized generations of folds, and contemporaneous with wall-rock alteration and subsequent mineralization. Flow directions of mineralizing solutions are deduced from the mineral zoning pattern; galena follows sphalerite paragenetically and ...
