摘要

Wall-Rock alteration is a replacement process, due as much to the mineralizing processes, and is very common and always associated with ore deposits at depth, esp. hydrothermal ore deposits. During the alteration process the original minerals are replaced by other minerals with different degrees, causing the changes in the texture, as well as the percentage of component and size of mineral grains. These changes can be characterized by multifractal model quantitatively. In this paper, on the basis of CIS technique, patterns are produced to simulate the process of alteration: one type of mineral is replaced by another type of mineral progressively. The result shows that, with a change in the degree of alteration (the relative percentage of the component of the original mineral changes from about 80%, 50% to 20%), the corresponding multifractal spectrum changed from left wing-developed, a bell-shape to a right wing-developed spectrum, and the corresponding specific values at q = 2 in multifractal spectrum also changes.
