摘要
西班牙伊比利亚山脉西北部的奥尔韦加一号剖面由晚侏罗世早期（ＬｏｗｅｒＫｉｍｍｅｒｉｄｇｉａｎＡｇｅ）沉积的碳酸盐岩组成，根据动植物群的特征、颗粒成分、基质类型及其结构划分出六种微相类型．它们在剖面上的组合代表一个由海进和海退岩系构成的沉积旋回．
A study is made of limestones of Upper Jurassian (Lower Kimmeridgian Age) in Olvega, Spain. Six microfacies types can be divided. The individual microfscies types are chsracterized by a definite fauna, flora, allochchems and matrixes. They present a complete sedimentary cycle of transgression and resression.
