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 کاملApplication of Strontium Isotope Analysis of Bone and Tooth in the Study of Ancient Immigrations
One of the important questions of archaeology is the study of the mobility and immigration of human groups. A common method for addressing these issues is to refer to the artifacts and archaeological findings left behind by the earlier cultures and to compare the forms, motifs, and production methods used among various ancient cultures, and hence, to explore the relationships and cultural excha...
متن کاملCollapse structures in Dowgonbadan region, Zagros fold- thrust belt
Allochthonous masses are common structures in Zagros fold-thrust belt. They are generally considered as collapse structures formed by the influence of gravity and in rock units with competency contrast. However, large allochthonous masses mapped in Dowgonbadan area in Dezful Embayment near the Mountain Front Fault (MFF) of Zagros show characteristics different from the belt common collapse stru...
متن کاملStrontium and lead isotope analyses for determining the geographic origins of grains.
A rapid determination method of (87)Sr/(86)Sr and Pb isotope ((204)Pb, (206)Pb, (207)Pb, and (208)Pb) ratios was applied to determining the geographic origin of grain crops. This new method is more economical in terms of both time and cost compared to conventional methods. We used samples of barley (n = 321), rice (n = 111), and wheat (n = 93) grown in various countries. (87)Sr/(86)Sr versus Sr...
