  10. 3 ) in shell of hyriopsis cumingii ( lea ), the prismatic layers and the nacreous layers are all composed of aragonite minerals, and aragonite crystallites in prismatic layers show obviously preferential orientation of [ 012 ] axis perpendicular to the shell layers, so it is considered that the orientation of aragonite crystallites in prismatic layers perhaps play an important role in deciding the orientation of aragonite crystallites in nacre and acts as one of template to resulting the formation of aragonite with [ 012 ] orientation perpendicular to nacreous layers in nacre

    3 )與海水貝殼明顯不同的是,三角帆蚌稜柱層礦物相與珍珠層一樣皆為文石相,同時查明稜柱層中文石晶體具[ 012 ]軸垂直殼層面的明顯的擇優取向。本文認為,三角帆蚌稜柱層中文石晶體的擇優取向可能對珍珠層中文石晶體的擇優取向存在模板導向的作用,導致珍珠層[ 012 ]定向的文石晶體的形成。
