| 摘 要： | 石榴石是冀北水泉沟偏碱性岩体的二长岩类和正长岩类中常见的矿物之一，通过对其产出特征和矿物成分的分析研究，认为石榴石是央浆与大岩岩和片麻岩等围岩反应形成的矽卡岩矿物，从而说明岩浆演化过程曾经历上地壳的同化混染作用，同时也说明成矿过程经历了从矽卡岩阶段→中低温热液阶段，而非单一的中低温热液金矿成矿模式。

| Abstract: | Garnet is one of the commom minerals of monzonitic and syenitic rocks from the Shui-quangou weakly-alkaline complex,northern Hebei.According to the study of its occurance and mineral compositions,garnet is inferred to be one of the skarn minerals formed by the contact-re-action between magma and marbles or gneisses,This implies that the process of magmatic evolu-tion involves assimilation and contamination of magma by upper-crust,and also that the process of metallogenesis is from skarn stage to the pegmatitic stage,and then to the mesoepithermal stage. This paper denies the singe metallogenic model of meso-epithermal gold deposit. |
