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呈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；运用分形理论对大韵律层进行研究之后，认为层状岩体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，推测这５个状态变量为：岩浆成分、压力、温度、氧逸度、重力
The rhythm structure of stratiform basic-ultramafic rocks in Panxi is developed. The rock minerals and geochemical characteristics of the rock show a multi-level cascade of rhythmic changes in the vertical direction. Through the comprehensive and detailed study of the prosodic structure, we find that the prosodic structure has the fractal characteristics. After the study of the large prosodic layer by using the fractal theory, it is considered that the formation of the prosodic structure of the layered rock mass may be controlled by five substantive state variables. Data analysis, speculated that the five state variables are: magma composition, pressure, temperature, oxygen fugacity, gravity
