Abstract

Abstract

In this paper, the fractal theory is applied to the fractal calculation of thickness of rhythmic layers in Panzhihua layered intrusion in Sichuan Province, China. In addition, this paper discusses the origin of the rhythmic stratification by means of computer simulation. The fractal research on the thickness of Panzhihua layered intrusion shows an excellent fractal structure with its dimension ranging between 1.4 and 1.8. The fractal dimension of thickness varies with different grades of rhythmic layers. The higher the grade of the rhythmic evolution is, the greater the fractal dimension of thickness is. The fractal dimension of rhythmic color thus simulated is close to that of the thickness of the measured rhythmic layer in addition to similar changing patterns, which indicate that a certain internal association is present between the thickness and the chrominance of the rhythm in the process of the magma evolvement, and that the gravity is an important factor of the formation mechanism of the rhythm. The coupling in space and time between earth gravity and other earth physical and chemical effects results in this kind of rhythmic pattern with spatio-temporal fractal structure.
