一、前言国际著名的前寒武纪地质学家,英国累斯特大学地质系B.F.温德利教授曾在1983年国际前寒武纪地壳演化讨论会上发言,述及前寒武纪变质岩区某些主要岩石——石英长石片麻岩、黑云片麻岩、黑云角闪片麻岩和黑云紫苏片麻岩的成因问题。例如,二十年前普遍认为苏格兰西北部的石英长石片麻岩是重结晶的沉积岩,但现在则普遍同意它们是由英云闪长岩、花岗闪长岩和花岗岩经重结晶后的产物。在中国,例如冀东变质岩分布区,虽有它的特殊性是否也有它的共性?这诚如B.F.温德利教授建议所说,“西格陵兰、拉
Preface An internationally renowned Precambrian geologist, Professor BF Windley, Department of Geology, University of Euston, UK, spoke at the International Precambrian Crustal Evolution Conference in 1983, Some of the main rocks - quartz feldspathic gneiss, biotite gneiss, black hornblend gneiss and black cloud perilla gneiss causes. For example, the feldspathic gneisses of the northwestern Scotland were generally believed to be recrystallized sediments two decades ago, but it is now generally accepted that they have been recrystallized from the tonalite, granodiorite and granite product. In China, for example, the distribution of the metamorphic rocks in Jidong has its commonalities even though its particularity is similar to that of Professor B.F. Windley’s suggestion: "West Greenland,
