| 摘 要： | 攀西层状基性－－超基性岩体的韵律结构发育，岩体的岩石矿物特征、地球化学特征在垂向上均叶多级套叠的韵律式变化。通过对韵律结构全面、详细的研究，发现韵律结构具有分形特征；运用分形理论地大韵律层进行研究之后，认为层状岩 韵律结构的形成可能受５个实质性状态变量控制；进一步结合地质资料分析，推测达５个状态为量力：岩浆成分、压力、温度、氧逸度、重力。

| Abstract: | Rhythms are well developed in the layered basic ultrabasic rock masses in Panxi region.The petrographic,mineralogical and geochemical characteristics vary in the style of multi levelly superimposed rhythms in vertical direction.By studying on the rhythms in detail and comprehensively,we have found that the rhythms have fractal features.After studying with fractal theory,we consider that there may be five substantial state variables controlling the formation of the rhythms.Analyzing with related geological materials,we conclude that the five substantial state variables are:magma composition,pressure,temperature,oxygen fugacity and gravity. |
