Stratigráficos

Stratigráficos refers to stratigraphy, a branch of geology that studies rock layers, or strata, and their sequential deposition. It is the study of these layered rocks, their form, composition, and the relationships between them, as a means of understanding the Earth's history. Stratigraphy is a fundamental tool in geological mapping and correlation, allowing geologists to determine the relative ages of rock formations and to reconstruct past environments and events. Key principles include the law of superposition, which states that in an undisturbed sequence of sedimentary rocks, the oldest layers are at the bottom and the youngest are at the top, and the principle of original horizontality, which posits that sedimentary layers are deposited in horizontal planes. Other principles, such as lateral continuity and cross-cutting relationships, further aid in interpreting geological history. Stratigraphic studies are crucial for resource exploration, such as oil, gas, and mineral deposits, as well as for understanding paleoclimates, paleontology, and seismic hazards. The analysis of stratigraphic sequences provides a chronological record of geological processes and life on Earth.
