Interpretation of Tidal Structures and Chaotic Deposits

🔍 We are exploring deposits in the Muelles Formation in Arroyo Carrete.

💡 These deposits are characterized by continuous and laminated structures.

🌊 The deposits consist of fine materials, and their porosity and permeability are affected by diagénesis.

🔍 The video explores unusual deposits of sand with fractures and fine sand without explanation from geological processes.

🗺️ In the column, there are compressions with oxidized fractures, and further up, there are sandy banks with estuary structures and channels.

🌊 There are bioturbated sandy deposits with vertical disturbances and tidal structures, as well as extensive tidal structures in the Lajas deposits.

The video discusses the interpretation of tidal structures and their deposition during periods of tidal pause.

The formation of Lajas is analyzed, highlighting the injection of material into the rock and the formation of domes due to magma intrusion.

The collapse of the domes leads to chaotic deposits with large blocks, resembling a volcanic eruption.

The video discusses the formation of volcanic and sedimentary components and the collapse of a Caldera.

It showcases the presence of blocks and debris resulting from the collapse of the Caldera.

The video explores the stratigraphy and composition of Vaca Muerta, highlighting its complex nature and the presence of different sedimentation periods.

🔑 The level of pause in sedimentation affects the dimension and connection of the concretions.

📸 The presence of orange-colored volcanic ash levels indicates periods of decreased sediment input.

🌊 The accumulation of sedimentary flows leads to the growth of concretions, which reduce in thickness due to compaction.

Different sediment levels transport organic matter

Organic matter concentration varies throughout the sedimentation period

Formation of new ramps and transfer of organic matter to the platform

⚡️ There is a relationship between the cycles found in the platform and the levels of discontinuities in the interior.

🌊 The moments of low sedimentary input correspond to degradation levels with sedimentation interruption.

🔬 Analyzing the elemental sequence and top levels is crucial for understanding the sedimentation process.
