The JORC Inferred Resource estimate of 38Mt is considered to be conservative, and solely based on the continuous and correlatable
Bulwer Coal Seam.
The Valdivia Group has not been sub-divided into correlatable
The El Jaguelito Formation, a unit correlatable
with the Nahuel Niyeu Formation, outcrops to the south around Sierra Grande, and is mainly composed of slates, phyllites and metawackes, metasandstones and minor intercalations of metaconglomerates, felsic-to-mafic metavolcanic rocks and metaignimbrites (Naipauer et al.
10C, 10G, 11C, D) and, interestingly, they have been found in levels stratigraphically correlatable
with the uppermost part of the Leza River section of the Leza Fm (Fig.
The latter form the most calcareous unit in the section, which is litho- and cyclostratigraphically correlatable
with the Vilsandi Beds and Kesselaid Member of the Jaagarahu and Muhu formations, respectively.
Although their age is uncertain, the similar sulphur isotope compositions and sedimentological features of the evaporitic deposits of both basins make us think that at least part of the evaporitic deposits of the Basque-Cantabrian Basin could be correlatable
with those in the Oncala Group.
This methodology is more rigorous and easier to apply in the coastal area due to the proximity to the reference datum (mean sea level) and the possibility of using directly correlatable
geological and geomorphologic markers (marine terraces and abrasion platforms).
Other authors indicate that the topographic depression is primarily due to tectonic subsidence and, in the absence of correlatable geomorphic or stratigraphic markers on both sides of the structure, propose a Plio-Quaternary vertical displacement of 350-400 m on the Palomera Fault (Rubio and Simon, 2007; Rubio et al.
Available data on long-term slip rate, a parameter usually applied to estimate indirectly earthquake recurrence assuming no interseismic displacement, is still limited due to the following reasons: (1) Some faults do not have correlatable markers on both walls, precluding reliable estimates of cumulative displacement and slip rate (e.
The stratigraphic units that crop out in the Juan Vich section, are physically correlatable
with the ones of Robles (1970), although they represent an age interval similar to the one proposed by Assens (1973a, 1973b).
2007), some selected sections (such as in the Val Fontanelle, Upper Val Trompia and in the Passo di Croce Domini-Passo Valdi areas, located around the southern border of the Adamello massif) show, beneath the famous Gastropod member of the literature (Lepsius, 1878; and so on), the presence of grey micritic limestones, yielding a marly-siltstone matrix, probably correlatable
with the Siusi member of the Werfen Formation, cropping out in the eastern Southern Alps.
Three main evaporitic cycles has been recognized, and, at least, 17 correlatable
halite levels have been identified in most of the wells, from Santa Barbara-1 to Carcelen-1, a lowermost fourth cycle only appears to be present in two wells, Carcelen-1 and Salobral-1, at the base of the K1 unit.
Due to the unique apparition of the storm facies along the studied siliciclastic unit it is easily correlatable
using genetic criteria.
In a more detailed study of the marine Jurassic of the Basque-Cantabrian Basin, the five benthic foraminiferal assemblages given here may be split further in smaller associations that may be correlatable
to depositional sequences in a similar way as shown in Cubaynes et al.
