双晶石

Lazurite,hauyne and nosean are sulfate-rich members of the sodalite group minerals,in the structures of which there are observed one-dimen sional or multidimensional structural modulations, anti-phase domain structures and twin domain structures.

在黝方石、蓝方石和青金石等富含［SO4］2-的方钠石族矿物的有序结构中，常见有沿着一个或几个方向的结构调制，并还常伴随出现反相畴、双晶畴等畴结构。

Fe(superscript 3+) occupied both tetrahedral sites in spinel block and trigonal bipyramid sites in mirror plane for LaFeMnAl(subscript 12-x-y)O19 (x=0.5, 1) hexaaluminate.

LaFeMnAl(下标 12-x-y)O19(x=0.5， 1)中Fe以Fe(上标 3+)位于六铝酸盐尖晶石结构中的四面体位和镜面层结构中的三角双锥位，其中后者为N2O分解的主要活性中心。

For example, alkaline elements can affect diffusion velocity of Zr, Si and O ions although these alkaline elements cannot exist in crystal structure of zircon. However, K rich media and Na rich media exert different effects on the growth of crystal form: in the K rich media, growth speed of prism faces in the vertical direction is much higher than that of pyramid faces, and {111} growth speed in the vertical direction is higher than {311},which decides the formation of bipyramids dominated by {311} pyramids; in the Na rich media, both prism and pyramid grow to a certain extent, but the former is smaller than the latter.{100} growth speed in the vertical direction is lower than {110}, while {111} growth velocity in the vertical diredtion is lower than that of {311},resulting in the growth of the crystal form characterized by {100} short prism and {111} pyramid.

例如，尽管碱性元素并不进入锆石晶格，但它们可以影响Zr、Si、O离子的扩散速度，但是富钾和富钠的介质对锆石晶形发育的影响是有差别的，表现为：在富钾的介质中，将导致柱面的法向生长速度较锥面快得多，而锥面中，｛111｝的法向生长又较｛311｝快，由此决定了形成以｛311｝锥为主的双锥状晶体；在富钠的介质中，柱面和锥面都有一定程度的发育，但前者弱于后者，而柱面中，｛100｝的法向生长较｛110｝慢，由此决定了形成以｛100｝柱和｛111｝锥为主的短柱锥状晶体。
