Geochemical Fractal Characteristics of Deep-Sea REE-Rich Sediments in the Western Pacific

At present, the challenge for geochemical prospecting of deep-sea, rare, earth-rich sediments is selection exploration sites. Because unpredictability offshore operations, distribution and survey line stations face great challenges. In this paper, we study fact that concentration geochemistry in space may be a part special complex process, which called multifractal. It requires large number indexes to characterize its scale characteristics. Based on multifractal spectrum, 38 indices Pigafetta Basin region western Pacific Ocean are divided into three categories. The distinguished by parameters. results multifractals good agreement with those cluster analysis principal component analysis. addition, basis analysis, further used filtering method extract element anomalies delineate enrichment regions. first clearly represents potential area. spatial technique proposed paper provide new idea sediments.
