Exploration Targeting from Prospectivity Modelling of Multiple Deposit Types in the Lachlan Fold Belt, NSW
Prospectivity modelling has been completed over the Lachlan Fold Belt, New South Wales, Australia, using the GIS based weights of evidence modelling technique to target porphyry Cu-Au, associated skarn Cu-Au, orogenic Au and VMS Au mineralisation. The Lachlan Fold Belt is a 700 km wide belt of Paleozoic accretionary terrains, stretching from Queensland to Tasmania. Porphyry and skarn mineralisa...
متن کاملWhat caused the Early Silurian change from mafic to silicic (S-type) magmatism in the eastern Lachlan Fold Belt?
One of the characteristic features of Ordovician tectonism in the east Lachlan Fold Belt is the occurrence of calcalkaline to shoshonitic basalts, which have been recognised as part of an intraoceanic arc environment (Glen et al. 1998), consistent with early tectonic interpretations (Oversby 1971; Scheibner 1973). Aside from typical traceelement abundances of intraoceanic arcs, critical evidenc...
متن کامل40Ar/39Ar and K–Ar age constraints on the timing of regional deformation, south coast of New South Wales, Lachlan Fold Belt: problems and implications*
The Lachlan Fold Belt is well known for its complex deformational history, with a number of orogenic events and associated structural styles recognised. Recent syntheses of this orogenic evolution have emphasised the difficulty of identifying fold-belt-wide deformational episodes and have inferred the existence of diachronous deformation zones with an overall merging of episodic orogenic events...
متن کاملGeology of the Amber - El Amino Area , Ecstall Metamorphic Belt ,
The Amber El Amino area is located 75 kilometres southeast of Prince Rupert. Access to the area is by helicopter from Prince Rupert or Terrace (Figure 1). The El Amino showing (BC MINFILE 103H 071) is located on Sulphide Creek (Figure 2) which drains eastward into Hanna (El Amino) Creek. The Amber showing (BC MINFILE 103H 171) is located 700 metres north of the El Amino showing. Hanna Creek dra...
متن کاملGeology of the East Harrison Lake Belt, Southwestern British Columbia
The East Harrison Lake belt (EHLB) refers to a northwest-trending belt of rocks occurring to the east of Harrison Lake in southwest British Columbia (Figure 1) which is currently the focus of exploration for ultramafic-related Cu-Ni (PGE). The geology of the EHLB will also be summarized as a 1: 50 000-scale compilation map (Ash et al., in preparation) incorporating both published and unpublishe...
