引言曾有学者提出,过菲律宾具有一个共同的前第三纪原地变质基底(Irving,1950;Gerva-sio,1971;Miranda,1977),而基底杂岩在成分上包括,已不同程度变质,并普遍被超镁铁质和镁铁质岩石切割的沉积岩,火山岩或与变质的角闪岩和长英质片岩伴生(Irving,1950;等);其上覆盖着千枚岩和板岩与相伴的大理岩透镜体(Gervasio,1966)。除此之外,对于它们的年龄,构造意义或相互之间的关系实际上是一无所知的。本文中将介绍从东南吕宋的两处基底杂岩所获得的地质和地质年代学方面的新资料,这
INTRODUCTION Some scholars have suggested that the Philippines had a common pre-Tertiary metamorphic basement (Irving, 1950; Gerva-sio, 1971; Miranda, 1977), while the basal complexes were composed in composition with varying degrees of metamorphism, And are generally associated with sedimentary rocks, volcanic rocks cut by ultramafic and mafic rocks or associated with metamorphic amphibolite and feldspar lithofacies (Irving, 1950; et al.); And phyllite and slate Of marble lenses (Gervasio, 1966). In addition, the age, structure, or relationship to each other is virtually unknown to them. This article will introduce new information on geology and geochronology obtained from two basement complexes in the Luzon area of southeastern China, which
