本文根据微量元素Rb、Ba、Sr、REE、Th、Sc和Co的含量,进一步完善了已建立起来的圣弗朗索瓦山脉火成杂岩体的熔融和结晶模式。与巴特勒丘陵破火山口和托姆索克地区伴生的两类相对未分异的深成岩体,可能是由下地壳岩石部分熔融形成的。其中,前者可能有30%左右是由石英闪长岩、硬砂岩或亚杂砂岩聚合熔融形成的;后者则可能有30%左右是由含长石砂岩或长石砂岩平衡熔融形成的。巴特勒丘陵破火出口中的富硅岩石,可能是由分馏结晶作用形成的。希尔弗曼花岗岩具有内部分带现象,它是由分异的花岗岩经进一步的结晶作用形成的。但是未分异的希
Based on the contents of the trace elements Rb, Ba, Sr, REE, Th, Sc and Co, the melting and crystallization patterns of the established igneous rocks of the Saint-Francois igneous zone are further improved. Two relatively undifferentiated plutons, associated with the Butler Hills caldera and the Tomsk area, may have been partially melted by the lower crustal rocks. Among them, about 30% of the former may be formed by the melt polymerization of quartz diorite, hard sandstone or sub-gritstone. The latter may be formed by the equilibrium melting of feldspathic sandstone or feldspar sandstone. Silicon-rich rocks in the fracture of Butler Hill may be formed by fractional crystallization. Silverman granite has an internal zonation, which is formed by the further crystallization of distinct granites. But undivided hope
