In contrast, it is present in the rest of the sequence Etoposide clinical trial from the basement to the Cadna-owie Formation (Fig. 5), and it has influenced the geometry of all Jurassic aquifers of the GAB. The Dariven Fault is recognisable on all seismic surfaces (Fig. 5), and it is also mapped

at the surface, and therefore of significance to the entire stratigraphic sequence. The displacement along this fault is larger in the lower seismic surfaces than in the upper surfaces, indicating different episodes of fault movement. The largest displacements associated with these faults were observed where they intersect Cross Section 07 (Fig. 2), with displacements of up to 120 m in the Dariven Fault and 160 m in the Maranthona Structure recorded. In the Maneroo Platform area (Fig. 1), the Stormhill

Fault and Westland Structure are the only regional structures previously mapped but additional structures were identified in this study (Fig. 4d). The maximum displacements of 300 m identified during the present study along these structures are consistent with those defined by Vine et al. (1965). However, the Stormhill Fault extends further than suggested by previous surface geological mapping. Two additional regional faults have been identified in this study, to the west of the Stormhill Fault. These two faults are not visible at the selleck monoclonal humanized antibody surface as they are covered by sediments almost deposited by the Thomson River (Fig. 2), but they

are clearly visible on the Cadna-owie seismic surface and are herein named the Thomson River Fault and Lochern Fault (Fig. 5). The Thomson River Fault has a greater regional influence than the other faults near the Maneroo Platform, as documented by vertical displacements up to 650 m on Cross Section 23 (Fig. 4d), while the Lochern Fault shows displacements of up to 200 m. The displacement observed along the Thomson River Fault is consistent with the one observed by Ransley and Smerdon (2012) at the Stormhill Fault. Most local faults intersect a limited number of stratigraphic units and displacements are usually smaller compared to regional faults. Local faults related to the period of seismic activity during the Early Permian do not appear to affect any GAB aquifers. Considering this, their influence on hydraulic connectivity between aquifers or aquitards, as well as on gas migration, is probably limited as they only intersect the Aramac Coal Measures and not the Betts Creek Beds (Fig. 5). However, local faults related to the period of seismic activity during the Early Cretaceous resulted in displacement of the GAB aquifers. These structures could therefore be important as conduits or barriers to groundwater flow, but will not have any influence on gas migration as they are located in areas where the coal seam bearing units are generally absent (with the exception of the Corfield Fault).
