摘要：本研究对甘肃金塔一个地窝南遗址的9件绿松石样品进行物相、成分、铅锶同位素检测得出:所取样品的拉曼峰位于3473 cm^(-1),1035 cm^(-1),815 cm^(-1),645 cm^(-1),414 cm^(-1),223 cm^(-1)等处,样品强峰位于1035 cm^(-1)附近。该遗址绿松石的主要成分为Al_(2)O_(3),P_(2)O_(5)和CuO,其中w(Al_(2)O_(3))为32.14%~37.48%,w(P_(2)O_(5))为33.09%~42.50%,w(CuO)为6.05%~7.68%,除此之外,还有少量和微量的Fe_(2)O_(3),SiO_(2),MgO,CaO,Na_(2)O,K_(2)O,TiO_(2),BaO,SnO_(2),SrO,ZnO,VO等元素。铅锶同位素比值^(208)Pb/^(204)Pb在37.037~40.032之间,^(207)Pb/^(204)Pb在15.039~16.333之间,^(206)Pb/^(204)Pb在18.500~29.685之间,^(87)Sr/^(86)Sr在0.710054~0.712786之间。对比新疆哈密及陕西洛南辣子崖等五处绿松石矿数据得出。新石器时代晚期金塔一个地窝南遗址绿松石至少有3处不同的矿源,其中一处指向新疆哈密地区。以^(207)Pb/^(204)Pb+^(87)Sr/^(86)Sr为组合的铅锶同位素比值组分模型,可以成功将不同矿源的绿松石区分开。先秦“绿松石之路”传播除了“洛河一线”“太行山西麓”外,还有“河西走廊”一线。
In this study,nine turquoise samples from the southern Yigediwo Site in Jinta area,Gansu province are detected for their physical phases,compositions and lead and strontium isotopes.The Raman peaks of the turquoise samples are located at 3473 cm^(-1),1035 cm^(-1),815 cm^(-1),645 cm^(-1),414 cm^(-1) and 223 cm^(-1),and the strong peaks of the samples are located near 1035 cm^(-1).The main components of turquoise are Al_(2)O_(3),P_(2)O_(5) and CuO,among which w(Al_(2)O_(3))content is 32.14%to 37.48%,w(P_(2)O_(5))content is 33.09%to 42.50%,and w(CuO)content is 6.05%to 7.68%.In addition,there are also a small amount of Fe_(2)O_(3),SiO_(2),MgO,CaO,Na_(2)O,K_(2)O,TiO_(2),BaO,SnO_(2),SrO,ZnO,VO and other elements.Lead and strontium isotope ratios of ^(208)Pb/^(204)Pb are 37.037 to 40.032,^(207)Pb/^(204)Pb are 15.039 to 16.333,and ^(206)Pb/^(204)Pb are 18.500 to 29.685.^(87)Sr/^(86)Sr ranges from 0.710054 to 0.712786.By comparing the data of five turquoise deposits in Xinjiang Hami,and Luonan Tangziya of Shaanxi province,it is concluded that there are at least three different sources of turquoise in Jinta Yigediwo site in the late Neolithic Age,one of which points to Xinjiang Hami.The lead and strontium isotope ratio model,combined with ^(207)Pb/^(204)Pb+^(87)Sr/^(86)Sr,can successfully distinguish turquoise from different ore sources.Therefore,in the pre-Qin period,the“Turquoise Road”spread along the“Hexi Corridor”in addition to the“Luohe River Line”and“The Western Foothill of Taihang Mountain”.
