| Lead Isotopic Composition Of Two Types Of Lead-Zinc Deposits In Southern Hunan |
|
|
| Abstract:The two types of lead-zinc deposits occurring in Devonian strata of southern Hunan refer to deposits in famous Dongpo and Xianghualing ore fields and deposits far from small Yensbanian granitic bodies. Based on 27 analyses of lead isotopic composition (Table l, Fig. 1) , combined with geological and geochemical setting of the deposits, the present paper deals preliminarily with such problems as sources of ore-forming materials, metallogenic phases and stages, ore genesis and evolution of the earths crust in Hunan in the light of lead isotopic composition, source of lead in ore (Fig. 2), lead isotopic chronometry (Fig.3) and sources and two-stage evolution of metallic ore materials(Figs. 4 and 5), indicating that the two types of lead-zinc deposits might be products of the same metallogenic series closely related to each other in genesis. |
