摘要
西准噶尔是中国晚古生代花岗岩发育的主要地区之一,沿著名的达尔布特断裂带发育的后造山花岗岩带一直是西准噶尔花岗岩研究的焦点,其中夏尔莆岩体又是该花岗岩带中极其重要的岩体之一.通过对夏尔莆岩体的研究,从地球化学特征结合构造、岩浆岩等其他成矿因素得出该岩体总体特征与成矿关系.夏尔莆岩体岩石化学特征表明,寄主岩石富Al2O3、CaO和MgO,岩石化学图解和岩石化学参数证明其属于钙碱性准铝质—过铝质I型花岗岩.
The Late Paleozoic Xiaerpu granite is the most important intrusive body in the post-collision granite belt developed along the Darbute fault in West Junggar, Xinjiang Region. Based on the study of geochemistry and petrochemistry,combined with tectonic setting, magmatic rocks and other metallogenic factors, the relationship between the characteristics of the Xiaerpu granite and mineralization is recognized. It is revealed that the ore-host rock is rich in aluminum, calcium and magnesium. The rock body belongs to calc-alkali quasi-aluminous or peraluminous I-type granite.
