摘要:

This short note presents the results of triclinicity determination of purified K‐feldspars from three spatially related granitic bodies (Kalunga Granodiorite, Watsonville granite, and Elizabeth Creek granite, ECG) in west Herberton, Queensland. The systematic decrease of triclinicity values (as 5 index) with increasing weight percent K2O and differentiation indices, decreasing colour indices, and K/Rb ratios is considered to provide an additional line of evidence for a possible co‐genetic relationship of the intrusives. The second phase of the Elizabeth Creek Granite (ECG II) is a late stage intrusive and its emplacement may explain the close spatial association of ECG members and the economic mineralization in the district.
