| 摘 要： | 本文提供了不同成分的8大类主岩(偏铝质(超)基性岩、过碱性(超)基性岩、偏铝质中性岩、过碱性中性岩、偏铝质酸性岩、过碱性酸性岩、过铝质酸性岩、超酸性岩)中28个矿物(橄榄石、单斜辉石、斜方辉石、角闪石、黑云母、金云母、斜长石、钾长石、石英、磁铁矿、钛铁矿、石榴石、锆石、磷灰石、绿帘石、黄玉、榍石、堇青石、蓝方石、石榴石、霞石、白磷钙矿、镁铁钛矿、板钛矿、黄长石、钙钛矿、尖晶石、金红石)的69个化学元素(Li、Rb、Cs、K、Na、Ca、Sr、Ba、Mn、Fe、Mg、Cu、Pb、Zn、Co、Ni、Be、La、Ce、Nd、Sm、Eu、Gd、Tb、Dy、Ho、Er、Tm、Yb、Lu、Y、Sc、Cr、In、Ga、Al、B、Cd、Sb、Bi、U、Th、Zr、Hf、Si、Ti、Ge、Sn、Mo、Nb、Ta、W、V、P、F、Cl、S、N、O、C、As、Pu、Re、Os、He、Ne、Ar、Xe、Kr)和1个化学一价原子团OH的分配系数。综合分析对比表明,矿物、熔体的成分和结构是分配系数的最重要的控制因素。对前人未讨论过的矿物结构和熔体铝过饱和度这两个因素应引起重视。最后,本文分析了矿物-熔体间元素分配系数的研究现状、存在问题,指出了这一领域今后的研究方向。

| Abstract: | This paper presents partition coefficients of 69 chemical elements (Li, Rb,Cs, K, Na, Ca, Ba, Sr, Mn, Fe, Mg, Cu, Pb, Zn, Co, Ni, Be, La, Ce, Nd,Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb, Lu, Y, Sc, Cr, In, Ga, Al, B,Cd, Sb, Bi, U, Th, Zr, Hf, Si, Ti, Ge, Sn, Mo, Nb, Ta, W, V, P, F, Cl,S, N, O, C, As, Pu, Re, Os, He, Ne, Ar, Kr and Xe) and the univalentradical (OH) in 28 minerals (olivine, clinopyroxene, orthopyroxene, amphibole,biotite, Phlogopite, plagiocla--se, K--feldspar, quartz, magnetite, ilmenite, garnet,zircon, apatite, allanite, topaz, sphene, cordierite, hauyne, leucite, nepheline,whit--lockite, brookite, petovskite, melilite, armalcolite, spinel and rutile) from8 types of rocks, namely metaluminous (ultra) basic rock, peralkaline (ultra)basic rock, metaluminous intermediate rock, peralkaline intermediate rock,metaluminous acid rock, peralkaline acid rock, peraluminous acid rock andultra--acid rock. It is found through an integrated ahalysis and comparison thatthe composition and structure of minnerals and melts seem to be the mostimportant factors controlling mineral--melt element partitioning. Importanceshould be attached to minral structure and Al--supersaturation of melt whichhave, not been discussed by research workers. Finally, the present state and theproblems to be solved in the study of mineral--melt element partition coeffici-ents are analysed, and the future trends of this research field are predibted. |
