锆石晶形的变化主要决定于产出母岩的岩石化学特征,尤其赴SiO_2、K_2O、Na_2O、CaO、Al_2O_3等主要组分的相互比例关系。在一定区域范围内,花岗岩类岩石的岩石化学成分的演化发展,在时间上有一定的变化规律,用晶形统计方法能定量地反映锆石的晶形特征及其变化趋势,有助于对花岗岩体的对比和岩石研究。
The changes of the zircon crystal form mainly depend on the petrochemical characteristics of the producing parent rock, especially the relative proportions of the main components such as SiO 2, K 2 O, Na 2 O, CaO and Al 2 O 3. In a certain area, the evolution and development of the petrochemical composition of granitic rocks have some changes in time, and the crystal form statistics can quantitatively reflect the crystalline characteristics of zircon and its changing trend, which is helpful to the granite body Contrast and rock research.
