During the latter part of the Phanerozoic, numerous iron oxide(-Cu-Au) (IOCG) systems formed in parts of the Cordillera of North and South America. They occur in diverse tectonic and magmatic settings with considerable variety in deposit associations and characteristics. Although there are general patterns, there is no simple, all-encompassing descriptive model; a comparison with the diversity ...

BACKGROUND The least costly management strategy for patients undergoing laparoscopic cholecystectomy is unclear. METHODS A decision model incorporating cost ratios, test accuracy, complication, and failure rates was used to determine the costs of 4 peri-laparoscopic cholecystectomy strategies: endoscopic retrograde cholangiopancreatography (ERCP), intraoperative cholangiography (IOCG), endosc...

[1] We introduce a new approach to the joint inversion of multimodal geophysical data using Gramian spaces of model parameters and Gramian constraints, computed as determinants of the corresponding Gram matrices of the multimodal model parameters and/or their attributes. We demonstrate that this new approach is a generalized technique that can be applied to the simultaneous joint inversion of a...

Recognizing footprints of Fe-oxide(-Cu-Au) ("IOCG") mineralization depends on the perspective that the beholder has on the nature and origin of these deposits. This follows from the fact that no simple descriptive model can adequately capture the diversity of the systems that are included in this family (any more than for epithermal deposits or similar broad classes). Nor, is there any semblanc...
