Resumen de La Mancha Triassic and Lower Lias Stratigraphy, a well log interpretation
The Stratigraphy of the Triassic Keuper and the Lowermost Liassic sedimentary section has historically attracted much less attention than the adjacent sediments of Muschelkalk and Buntsandstein, and Lower to Middle Lias. A twelve wells correlation has been prepared to demostrate the arrangements of facies in these formations, as well as their repective ordering in sequences. Well data show the existence of comlex multistage thick evaporitic sequences in the lower more saline K1 unit, and in the upper relatively more anhydritic K4-K5,. A clastic episodes K2-K3 is quite extended across the zone with several sand rich fairways. The topmost Keuper K6 unit is a very good marker. Sedimentation continued with thick evaporitic section, the Anhydrite Zone, which has a significant halite episode in the central part of the cross section. It is remarkable the good correlation between outcrops and well data.
