Study on the Sulfur and Lead Isotope Geochemistry of the Shagou Ag-Pb-Zn Deposit in West Henan Province
摘要
Abstract
Shagou large-scale Ag-Pb-Zn deposit is a structure controlled alteration type depos-it, which is located in the western part of the Xiong'ershan in the south margin of north China cra-ton.The isotope data of the quartz -polymetallic sulfides in the main ore -forming stage show thatδ34S/‰varies from -1.0‰ to 6.3‰ with an average of 2.0‰, implying that sulfur is mainly derived from mantle and minority derived from crust .The 206 Pb/204 Pb of the ore varies from 17.768 to 17.854, 207Pb/204 Pb varies from 15.485 to 15.578, and 208Pb/204 Pb varies from 38.462 ~38 .695 , which have narrow fluctuations and belong to normal Pb scope .According to the relevant characteristic parameters , its structure pattern and chart of the Pb , it is believed that the Pb of the ore is mainly derived from mantle and minor derived from crust .The isotope compositions of sulfur and lead in deposit indicate that the metallogenic materials are derived from the mixture of mantle and crust in orogenic process , and mainly from the mantle .关键词
