Revision as of 14:53, 16 July 2015
, 14:53, 16 July 2015→Facial variations in Vaca Muerta Formation in the margin of the Neuquén basin
This association includes facies 3, interpreted as a part of the mixed platform ([[:File:3.png|Figure 3B]]).<ref name=Tomassini />

The basal transegresive sequence in this sector of the basin retains the characteristics of sourcerock constant across large areas.<ref>Veiga, R. D., & I. A.

The Lowstand System Tract (LST) is not present, the Transgressive System Tract (TST) is very small and corresponds to the regional flood event. The section is dominated by high sea deposits prograding (Highstand System Tracts) where three subsequenceares individualized: A, B and C.

As shown in Figure X facial change area of Vaca Muerta shale in the prograde complex is located inmediately to the west. From east to west the high sea sequence comprises proximal or platformfacies in the entire registry. In the location of CVS.x-1 (see Figure x) a spur is accompanied by a break in paleoestructuralslope where the structural nose would be limited by faults with subtle shift.
