遵义松林含磷岩系层理缝和节理缝内的白色矿物集合体呈粉末状、姜状和晶须状产出。作者利用X射线衍射(XRD)、扫描电镜及能谱(SED)对其进行测试分析,确定该矿物为泻利盐,化学式为Mg SO4·7H2O,扫描电镜下呈晶须状、姜状等不同形态,经计算,其晶胞参数与理想值存在较小差异。泻利盐的形成可能与含磷岩系遭受的风化作用、淋滤作用和蒸发-结晶作用有关,原岩为其提供重要的物质来源。 Zunyi Songlin phosphorus-bearing strata and seam joints within the white mineral aggregates were powdery, ginger and whisker-like output. The authors used X-ray diffraction (XRD), scanning electron microscopy and energy dispersive spectroscopy (SED) to test the analysis to determine the mineral salt water, chemical formula MgSO4 · 7H2O, scanning electron microscopy was whisker-like, ginger and other different Morphology, calculated, the unit cell parameters and the ideal value there is a small difference. The formation of salt water may be related to the weathering, leaching and evaporation-crystallization of phosphorus-bearing rocks, which provide important source of material for them.
