| Abstract: | The paper studies petrology,geochemistry,Nd,Sr isotope geochemistry of Carboniferous volcanic rocks in Chagannur iron deposit located in northeastern Yili block in western Tianshan.The rocks consist of basalt(a little),andesite,trachyte,rhyolite and volcaniclastic rock.Most of them belong to high-K calc-alkaline and shoshonite series,whereas a few rocks belong to calc-alkaline and low-K tholeiitic basalt.They are enriched in LREE and LILE(Rb,Ba,Th and U) with obvious depletions of Nb,Ta and Ti,which suggest... |
