The 190Pt-4He age of isoferroplatinum from andesitic fluid-explosion breccias (fluidolites, a new type of platinum-bearing rock) of the Poperechnoye deposit (Malyi Khingan, Russia) was estimated as 125 ± 21 Ma. This age correlates well with peak magmatic activity in the eastern Central Asian orogenic belt caused by upwelling of slab-window asthenosphere in a transform continental margin setting.

Poperechnoye矿床的安山岩流体中的天然铂的同位素年龄(俄罗斯,马里)

190铂- 4从Poperechnoye存款(Malyi兴安,俄罗斯)的安山岩流体爆炸角砾岩(fluidolites,新型铂承载岩石)isoferroplatinum的他的年龄估计为125±21毫安。这个年龄与中亚东部造山带的岩浆活动高峰有关,该峰岩浆活动是由板块窗口软流圈在转换大陆边缘环境中上升引起的。
