the ree enriched residual melt penetrated into the top of intrusion would be the products of nepheline syenite magma produced in the process of differentiation.
稀土元素矿床是霞石正长质巖浆分异残余熔体的产物,侵位于巖体最高层位。
by observing the melt course and analyzing the measurements of glass samples, the feasibility of nepheline syenite replacing part of raw material for the float glass is discussed.
通过对熔化过程的现察和对玻璃样品有关性能测试结果的分析,讨论了霞石正长巖作为浮法玻璃原料的可行性。
in addition, mineral assemblage and gabbro similar to gabbro pegmatite; and nepheline syenite nepheline syenite rock similar pegmatite and so on.
此外,还有矿物组合与辉长巖相似的辉长伟晶巖;与霞石正长石相似的霞石正长伟晶巖等等。
by observing of the melt course and by analyzing the measurements of glass samples, the feasibility of nepheline syenite as raw materials for the green float glasses was discussed.
