前言纽约西北鲍尔曼特—爱德华兹(Balmat-Edwards)pb-Zn 矿赋存于中元古代格伦维尔系碳酸盐和钙—硅酸盐大理岩中,从1915年此矿发现以来,虽然由于遭受过高级角闪岩变质作用从而导致矿床成因复杂化,但对于它们的形成模式和时代问题已经有了相当的研究。尽管最早的研究者提出过诸如高温岩浆成因和(或)变质成因见解,但现在一般认为矿床的就位是在变质作用之前。这项研究工作包括了福勒(Fowler)矿体矿石和脉石的硫、碳和氧同位素分析,
Preface The Balmat-Edwards pb-Zn deposit in the northwestern New York City occurs in the Mesoproterozoic Grenville Carboniferous and Calc-silicate marbles. Since its discovery in 1915, Although the formation of the orebodies is complicated by the metamorphism of the advanced amphibolite, considerable research has been conducted on their formation patterns and epochs. Although the earliest researchers have suggested such as pyro-magmatic genesis and / or metamorphism, it is now generally accepted that the deposit is in place prior to metamorphism. This research includes sulfur, carbon and oxygen isotopic analysis of the ore and gangue from the Fowler ore body,
