Abstract
The Guadix Basin became established as an intramontane basin in
the central sector of the
Betic Cordillera at the beginning of Late Miocene time. Its geodynamic
evolution starts with a unit of
Tortonian marine sediments and is completed by a unit of Late
Turolian–Pleistocene continental sediments.
In the two units, six depositional sequences have been differentiated
whose boundaries, in most
cases, coincide with tectonic events. Geohistorical diagrams show the
results of quantitative analyses
of subsidence in the northern sector of the basin and permit correlation
of the main events with significant
changes in the history of subsidence and uplift. A period of strong subsidence
occurred at the
beginning of Tortonian time causing the formation of a marine basin
800 m deep. The mid- and end-Tortonian
tectonic events involved periods of uplift leading to shallowing in
the basin. After continentalization
at the end of the Tortonian, the basin was uplifted continuously from Late
Turolian to Late
Pleistocene times, finally accumulating sediments at a height of 1000 m.
