**Simancas Group**
**Definition**
The Simancas Group is a geological formation located in the Iberian Peninsula, known for its significant sedimentary rock sequences dating from the Paleozoic era. It provides valuable insights into the region’s geological history and tectonic evolution.
**Article**
### Overview
The Simancas Group comprises a series of sedimentary rocks primarily found in northern Spain. These rocks were deposited during the late Paleozoic era, particularly in the Carboniferous period, and include various lithologies such as sandstones, shales, and limestones.
### Geological Significance
This group is important for understanding the sedimentary environments and tectonic processes that shaped the Iberian Massif. The Simancas Group records marine and deltaic conditions, reflecting changes in sea level and sediment supply during its formation.
### Stratigraphy and Composition
The stratigraphic sequence of the Simancas Group reveals alternating layers of clastic and carbonate sediments. Fossil content within these layers aids in dating and correlating the strata with other regional geological units.
### Research and Applications
Studies of the Simancas Group contribute to broader knowledge of Paleozoic paleoenvironments and have implications for natural resource exploration, including hydrocarbons and minerals.
