it truly is with excitement that I write the foreword to this wonderful booklet. a variety of observations in geology and solid-earth geophysics will be - plained when it comes to fractal distributions. during this quantity a set of - pers considers the fractal habit of the Earth's continental crust. The publication starts off with a superb introductory bankruptcy via the editor Dr. V.P. Dimri. floor gravity anomalies are identified to convey power-law spectral habit less than quite a lot of stipulations and scales. this is often self-affine fractal habit. factors of this habit stay arguable. In bankruptcy 2 V.P. Dimri and R.P. Srivastava version this habit utilizing Voronoi tessellations. one other method of figuring out the constitution of the continental crust is to exploit electromagnetic induction experiments. back the implications usually show energy legislation spectral habit. In bankruptcy three ok. Bahr makes use of a fractal established random resister community version to provide an explanation for the observations. different examples of power-law spectral observations come from a variety of good logs utilizing numerous logging instruments. In bankruptcy four M. Fedi, D. Fiore, and M. los angeles Manna make the most of multifractal types to provide an explanation for the habit of good logs from the most KTB borehole in Germany. In bankruptcy five V.V. Surkov and H. Tanaka version the electrokinetic currents that could be as- ciated with seismic electrical signs utilizing a fractal porous media. In bankruptcy 6 M. Pervukhina, Y. Kuwahara, and H. Ito use fractal n- works to correlate the elastic and electric houses of porous media.
