...F ig . 8. Plan projections of (a) the Charlotte and (b) the Flanagan faults, showing the position of orebodies adjacent to the faults and the distribution of alteration types in the fault zone rocks. Drill hole intersections are flagged as containing sericite (+ albite) + ankerite + pyrite...

... currents, and that the main controls on the geometry of the reservoir body were sedimentary processes ( Harding et al., 1990 ; Mattingly and Bretthauer, 1992 ; Newton and Flanagan, 1993 ).

... attention ( Cosgrove & Hillier 2000 ) or have been generically described as ‘massive sandstones’ ( Lonergan et al. 2000 ). Injected sandstones in the Alba Field are well known ( Newton & Flanagan 1993 ; Lonergan et al . 2000 ), but a recent review of the core record reveals a much greater...

... (400 m long by 30 m wide) emanate from the margins of the Alba channel sandstone along fault planes. An analogy is drawn between these dykes, and the peripheral dykes formed at the margins of laccoliths as a result of the flexing and subsequent fracturing of the overlying strata. ‘Decompacting...

... of estimating the depth to basement from magnetic data rely on the simple assumption that the geometry of the causative source has an infinite depth extent ( Flanagan and Bain, 2013 ). This assumption ignores the fact that the thickness of the magnetized layer will be depth limited by either the crust-mantle...

... of scenarios including variations in rupture directivity and path-propagation effects. Large ( M W > 6.0) damaging earthquakes are infrequent, and near-fault observations of ground-motion time series are limited to sparse numbers of recording stations. Consequently the database of recorded ground motions...

... structure, such as tomographic analysis, can provide high-resolution regional and global velocity models that improve the relative and absolute locations of hypocenters (e.g., Aki and Lee, 1976 ; Koch, 1985 ; Johnson and Vincent, 2002 ; Murphy et al. , 2005 ; Flanagan et al. , 2007 ). To locate...

..., when dealing with free-surface topography and nonplanar fault surfaces, the finite-element method is far superior to the widely used finite-difference method. Among different finite-element implementations, the explicit finite-element method with second-order elements and one-point integration...
