RT Journal Article T1 System Tracts, Secuencias de Depósito y Megasecuencias: geometrías y modalidades de superposición T1 System Tracts, Depositional Sequences and Megasequences: geometries and superposition modalities A1 Martínez del Olmo, W. AB The geometry and the areas of erosion/deposition of the System Tracts of which Depositional Sequences are made up of, and the ways in which the fatter are superimposed, are controlled by several factors. These factors can be considered to be grouped in a decreasing order of revelance, as follows: 1) Configuration Factor. 2) Depositional Area Factor and 3) FYogradation Factor. The first factor determines three big scale configurations, while the other two make possible the identificación of Depositional Sequences according to eight basic geometries PB Sociedad Geológica de España YR 1996 FD 1996 LK http://hdl.handle.net/10272/11434 UL http://hdl.handle.net/10272/11434 LA spa DS Repositorio Institucional de la Universidad de Huelva RD 30 may 2026
