BENNABEOLA QUARTZITE FORMATION Meaning and
Definition
-
The Bennabeola Quartzite Formation is a geological formation that is predominantly composed of quartzite rock. It is named after the Bennabeola Hill located near Montelparo, in the province of Fermo, Italy. This formation is part of the Marnoso-Arenacea Basin, which is a sedimentary basin in the northern Apennines.
Quartzite is a metamorphic rock that forms when sandstone is subjected to high levels of heat and pressure. The Bennabeola Quartzite Formation exhibits a well-developed metamorphic texture characterized by interlocking quartz grains with a granoblastic texture. This rock is generally light gray in color and displays excellent hardness and resistance to weathering and erosion.
The Bennabeola Quartzite Formation is an important unit in the geological record as it provides valuable insights into the tectonic history and sedimentary processes that shaped the northern Apennines. It represents a high-energy depositional environment associated with the initial stages of the syn-orogenic deformations of the Marnoso-Arenacea Basin. The formation also contains trace fossils and sedimentary structures that indicate the presence of ancient marine life and the dynamics of paleoenvironments.
The Bennabeola Quartzite Formation has been extensively studied by geologists and paleontologists due to its unique characteristics and significance in understanding the geological history of the region. The formation's composition, texture, and paleontological content provide valuable clues about the geological processes that occurred millions of years ago, contributing to our understanding of Earth's dynamic past.
