细碧岩及角斑岩比普通玄武类和长英类岩石禽钠高,有钠长石,并且常伴生海底“地槽”相沉积。完全或几乎完全发育着绿色片岩相矿物组合的并具有玄武岩结构的岩石称为细碧岩。角斑岩是含有钠长石的各种长英岩类的变种。角斑岩的原生岩石可能是粗面岩、安山岩、流纹岩或橄榄粗安岩,常常发现它们遭到碱性交代。本文试图证明细碧岩和角斑岩不仅是变质的岩石,而且还是它们的交代岩。
Bilite and angular porphyry than ordinary basaltic rocks and fossils of avian species of sodium, albite, and often associated with the sea bottom “trough” phase deposition. Rocks that have been completely or almost completely developed with a combination of green schist facies and basalts are called spire. The angular porphyry is a variety of various peridotites containing albite. The primary rock of the hornorphic porphyry may be a trachyte, andesite, rhyolite or olivian gabbros, and they are often found to have been subjected to alkaline metasomatism. This article attempts to prove that the diagenetic and angular porphyry are not only metamorphic rocks, but also their metamorphic rocks.
