On Some Problems of the Lead Isotope Method and Its Application in Geology
Isotopenpraxis Isotopes in Environmental and Health Studies, 1985Some new trends in the mathematical modelling of the lead isotope evolution in connection with the dynamic development of the earth's crust and with the exchange of materials between the crust and the mantle are discussed. The mathematical modelling of the derivatives with respect to time of U/Pb and Th/Pb ratios instead of μ and W give the possibility

Geology of the Mount Costigan lead-zinc deposit, west-central New Brunswick.
2009The Mount Costigan Pb-Zn deposit is located about 40km east of Plaster Rock, New Brunswick within the Early Devonian Costigan Mountain Formation, in the Matapedia Cover Sequence (formerly the Cialeur Bay Synclinorium). It occurs about 250m east of the summit of Mount Costigan within a series of brecciated and unbrecciated crystal and lapilli tuff ...
