40Ar/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 کاملNative Lead at Broken Hill, New South Wales, Australia
Native lead, a rare mineral, occurs in a late-stage vein in the world’s largest lead – zinc – silver deposit, at Broken Hill, Australia. The lead-bearing vein consists mainly of laumontite, quartz, biotite and muscovite, together with minor amounts of lead, galena, sphalerite, molybdenite, and rare allanite-(Ce). Three types of fluid inclusions have been identified: two-phase brine inclusions l...

15 صفحه اولExploration 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...
