| 摘 要： | 潼关地区混合岩可划分为四大类及若干亚类,混合岩化的程度与南北向构造挤压力的强弱相关,且随着分布在不同的构造部位而具分带性,混合岩化在宏观上、微观上都表现了多期性;曾称的“花岗伟晶岩”系混合岩作用的产物,应称混合花岗岩。

| Abstract: | The migmatites in this district can be divided into four classes and several subclasses.There may exist certain relationship between The degree of migmatization and the intensity of the north-south tectonic pressures. The mig-matization shows a zoning character and this is related to the tectonic position. The migmatization is multistage both macroscopically and microscopically. The so-called 'granitic pegmatites' are in fact the product of migmatization and therefore should be called migmatic granites. |
