... of Bolivia and adjacent areas. The partly restricted marine El Molino Formation spans the Maastrichtian and Danian (°73–60.0 Ma). Deposition of the alluvial to lacustrine Santa Lucia Formation occurred between 60.0 and 58.2 Ma. The widespread erosional unconformity at the base of the Cayara Formation is 58.2...

...-Campanian) with a total accumulation of up to 1000 m of sandstones and shales. A period of tectonic quiescence followed that resulted in a regional sag basin characterized by thin-bedded, calcareous lacustrine deposits. This sequence includes the oil-prone shales and reservoir carbonates of the El Molino...

... whether orbital forcings influenced sedimentary records of the past, and if so, which had such an effect, can shed light on Earth’s climate sensitivity and global ice volume. To this end, we present a field- and drone-based cyclostratigraphy of the predominantly lacustrine El Molino Formation of the Late...

The clay films are interpreted to be inherited from the soil developed in the source deposit. Scattered among the cobbles...
