The deep origin of Kangjinla podiform chromitite is suggested by: that for the Kangjinla chromitite and the mantle peridotite rocks, the compositions of the chrome spinel, olivine and clinopyroxene are rather different, which indicates that the chrome spinel in the chromitite is neither the simple concentration of that in the host rocks nor with certain genic relation with mantle peridotite. Though the chromitite might be exotic for host rocks, both of them were carried from deep mantle to the shallow place by mantle plum.
康金拉铬铁矿石与矿体围岩地幔橄榄岩的铬尖晶石、橄榄石和单斜辉石等成分方面明显不同,认为矿石铬尖晶石并非是由副矿物铬尖晶石富集而成,与地幔橄榄岩也不存在成因联系,认为豆荚状铬铁矿床对于近矿围岩地幔橄榄岩而言为外来体,但两者可能均是由地幔深部被地幔柱带到上部。

The complete borosilicate assemblage grandidierite-prismatine-tourmaline is determined and their formation setting are investigated. A review on the nomination confusion of kornerupine minerals has been made and a new name, boro-prismatine, is recommended for the case occurrence of the mineral at Antarctica according to the composition and structure data.

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。
