Morphology and Texture of Polymetallic Nodules and their Association with Sediments of the Mexican Pacific
This research deals with a regional comparative analysis of nodule morphology and texture with pelagic sediment distribution. Samples were collected on board of R/V El Puma during oceanographic cruise MIMAR VI. The study area is located in the northeastern portion of the Clarion Fracture Zone in the Economic Exclusive Zone of Mexico. The more abundant nodules sizes are smaller than 2 cm and discoid form with smooth and rough surfaces were dominant. Small sizes occur in the southern study area, while nodules larger than 4 cm are found in the northern portion. Sediments are enriched in Si, Al, Na, K, and Ti; in contrast the nodules are richer in Mn, Fe, Mg, Ca, Ni, Co, and Cu. Most of the Si and Al seem to be terrigenous probably due to the influence of winds carrying small particles from Vizcaino and Sonora deserts. Nodules are hydrogenic in the northern study area and diagenetics towards the south.
