Nephelinite is a rare type of strong alkaline volcanic rock mainly found in continental rift environments, oceanic islands, and large igneous provinces. Most of the world's nephelinites are associated with carbonatites and have similar geochemical characteristics to OIBs. Despite numerous studies on the characteristics and formation environments of nephelinite, the genesis of nephelinite and its relationship with carbonatite rock are still controversial, constraining the understanding of nature of mantle source and characteristics of metasomatic agents. The petrology, and whole-rock major- and trace elemental analysis was carried out on the nephelinites in Jieshi Mountain and Qixia Dafang Mountain in Shandong Province, and the composition of the primary magma is calculated according to the experimental petrological research results. The results suggested that the Shandong nephelinite originates from low degree (3%~5%) partial melting of 10%~40% carbonatite + peridotite. In addition, the primary magma has undergone the liquid immiscibility of the carbonate-silicate melt, which can match well with the major and trace elements characteristics and the symbiosis of the nephelinite in Shandong Province. It's also found that the calculated primitive magma has similar geochemical characteristics to that of typical kimberlite; thus, the author's study might have important implications for the origin of kimberlite magma.

霞石岩是一种少见的强碱性火山岩,主要产生于大陆裂谷、洋岛以及大火成岩省。世界上大多数的霞石岩与碳酸岩共生,具有与OIB相似的地球化学特征。目前,关于霞石岩的岩石学和地球化学已有大量研究,一般认为其能解释地幔性质和演化特征,但目前霞石岩的成因及其与碳酸岩的成因关系尚存争议,阻碍了对地幔源区性质和交代过程熔流体性质的理解。笔者选取山东地区代表性的且有一定研究基础的碣石山、栖霞大方山两地霞石岩进行岩石学和全岩主、微量元素地球化学分析,并根据实验岩石学研究结果对霞石岩母岩成分进行相关计算。研究显示,山东霞石岩起源于10%~40%碳酸岩+橄榄岩的低程度(3%~5%)部分熔融,而且原始母岩浆可能经历碳酸岩–硅酸岩熔体的液态不混溶,才能产生山东霞石岩的主、微量元素地球化学特征以及霞石岩–碳酸岩共生的现象。笔者计算出的原始母岩浆具有典型金伯利岩的地球化学特征,其研究可能对金伯利岩岩浆的起源具有重要启示意义。

霞石岩是一种少见的强碱性火山岩,主要产生于大陆裂谷、洋岛以及大火成岩省。世界上大多数的霞石岩与碳酸岩共生,具有与OIB相似的地球化学特征。目前,关于霞石岩的岩石学和地球化学已有大量研究,一般认为其能解释地幔性质和演化特征,但目前霞石岩的成因及其与碳酸岩的成因关系尚存争议,阻碍了对地幔源区性质和交代过程熔流体性质的理解。笔者选取山东地区代表性的且有一定研究基础的碣石山、栖霞大方山两地霞石岩进行岩石学和全岩主、微量元素地球化学分析,并根据实验岩石学研究结果对霞石岩母岩成分进行相关计算。研究显示,山东霞石岩起源于10%~40%碳酸岩+橄榄岩的低程度(3%~5%)部分熔融,而且原始母岩浆可能经历碳酸岩–硅酸岩熔体的液态不混溶,才能产生山东霞石岩的主、微量元素地球化学特征以及霞石岩–碳酸岩共生的现象。笔者计算出的原始母岩浆具有典型金伯利岩的地球化学特征,其研究可能对金伯利岩岩浆的起源具有重要启示意义。

Nephelinite is a rare type of strong alkaline volcanic rock mainly found in continental rift environments, oceanic islands, and large igneous provinces. Most of the world's nephelinites are associated with carbonatites and have similar geochemical characteristics to OIBs. Despite numerous studies on the characteristics and formation environments of nephelinite, the genesis of nephelinite and its relationship with carbonatite rock are still controversial, constraining the understanding of nature of mantle source and characteristics of metasomatic agents. The petrology, and whole-rock major- and trace elemental analysis was carried out on the nephelinites in Jieshi Mountain and Qixia Dafang Mountain in Shandong Province, and the composition of the primary magma is calculated according to the experimental petrological research results. The results suggested that the Shandong nephelinite originates from low degree (3%~5%) partial melting of 10%~40% carbonatite + peridotite. In addition, the primary magma has undergone the liquid immiscibility of the carbonate-silicate melt, which can match well with the major and trace elements characteristics and the symbiosis of the nephelinite in Shandong Province. It's also found that the calculated primitive magma has similar geochemical characteristics to that of typical kimberlite; thus, the author's study might have important implications for the origin of kimberlite magma.

霞石岩是一种分布较少的强碱性火山岩,主要出露于大陆(大陆裂谷以及克拉通区域)以及洋岛环境,通常以富集Th、U、Nb、Ta和轻稀土(LREE),亏损K、Pb,中度亏损Sr-Nd同位素为特征(罗丹等,2009;Zeng et al.,2010;陈立辉等,2012;何叶等,2019;Zeng et al.,2021)。已有研究发现,世界上大多数的霞石岩与碳酸岩伴生(Lee et al.,1997;Woolley et al.,2008;Brooker et al.,2011;Guzmics et al.,2012)。霞石岩通常被认为是由深部地幔极低程度部分熔融产生的熔体衍生而来的岩浆固结形成,且在其上升过程中没有受到明显的地壳混染,因此可以很好地反映地幔源区性质,是探究地幔性质及深部动力学过程的重要研究对象(罗丹等,2009;Zeng et al.,2010;陈立辉等,2012;Zeng et al.,2021),对理解地幔性质和演化过程以及壳幔相互作用等有重要研究意义。
目前,关于霞石岩的源区属性认识尚不统一,多数观点认为其源自富含挥发分的含金云母的交代岩石圈地幔低程度部分熔融(Sun et al., 1975; Class et al., 1997; Chen et al., 2006; Pfänder et al., 2018)也有部分学者提出,辉石岩、角闪岩(Dan et al., 1995; Pilet et al., 2004, 2005)、榴辉岩(Hirschmann et al., 2003; Kogiso et al., 2003, 2006)、碳酸盐化橄榄(Zeng et al., 2010)以及混合组分源区等不同模型。然而,也有学者指出,霞石岩并非地幔熔融形成的原始岩浆,而是碳酸盐化硅酸盐熔体在一定条件下通过液态不混溶作用演化而来(Koster et al., 1968; Lee et al., 1997; Kjarsgaard et al., 1998; Guzmics et al., 2012),因此关于霞石岩的源区性质和成因尚不明确,这制约了对地幔组成,交代作用过程,熔/流体性质等问题的理解。
山东地区有强碱性玄武岩分布,前人已开展了部分关于山东强碱性玄武岩的岩石学、地球化学研究,具有一定的研究基础(罗丹等,2009;Zeng et al.,2010,陈立辉等,2012;何叶等,2019;Zeng et al.,2021),为开展进一步研究工作提供支撑,但研究程度不深,因此,对其成因的认识较浅,而对其成因的定量厘定有助于更好的理解源区性质和霞石岩成因。鉴于此,笔者以山东碣石山(无棣大山)、栖霞大方山两个区域霞石岩为例,根据已有的实验岩石学研究结果,估算霞石岩源区物质组成以及原始母岩浆地球化学组分。
华北克拉通是中国最大最古老的克拉通,保留有>3.8 Ga的基底,其北以中亚造山带南缘为界,东南以中生代大别–苏鲁造山带为界限。根据年龄、构造演化、岩石组合和P-T-t轨迹,华北克拉通可进一步分为东部块体、西部块体和中央造山带。
研究区属于华北克拉通东部块体,处于华北克拉通的东南缘,以郯庐断裂为界,进一步分为郯庐断裂以西的鲁西地区和郯庐断裂以东的胶东地区。山东地区新生代岩浆活动发育,主要分为24.0~10.3 Ma和8.7~0.3 Ma两个时期(罗丹等, 2009)。早期岩浆活动强烈,主要分布在郯庐断裂带附近的狭窄区域,以弱碱性玄武岩(碱性橄榄玄武岩)为主;晚期岩浆活动以孤立的小火山为主,零星分布在远离郯庐断裂带的区域,以强碱性岩石(碧玄岩、霞石岩)为主,如栖霞大方山、栖霞马山、蓬莱老黑山以及鲁西无棣大山的霞石岩(图1)。
笔者选取山东栖霞大方山、鲁西碣石山两个地区新生代强碱性玄武岩为研究对象。栖霞所处大地构造位置:华北地台(Ⅰ级),胶辽台隆(Ⅱ级)、胶北隆起(Ⅲ级)与胶莱凹陷(Ⅲ级)两个Ⅲ级构造单元的结合部位。 地层属华北地层(Ⅴ),晋冀鲁豫地层区(Ⅴ4),鲁东地层分区(Ⅶ 4)。组成胶北隆起区的结晶基底为太古界胶东群,下元古界的荆山群和粉子山群深变质岩系,以不整合关系覆于其上。晚元古界蓬莱群,零星出露的中生界莱阳群、青山群、王氏群,残存在平顶山上的晚第三系火山岩流及第四系松散堆积物组成小区的盖层。栖霞位于华北地台鲁东地盾胶北隆起区中部的南缘与胶莱凹陷北缘之接合部位,横跨两个Ⅲ级构造单元。综观全区,可见为中间台隆,两侧台拗的构造格局。该区岩浆活动强烈,岩浆岩十分发育,主要形成于太古代、元古代和中生代,多呈岩基、岩株和岩脉产出。区域内较大规模的桃村断裂、马家窑断裂、栖霞断裂、盛家断裂皆具多期性、多变性和不均一性,它们既影响和改造着结晶基底的构造演化(张国刚等,2008)。碣石山位于山东省无棣县,地处郯庐断裂带西侧,华北盆地东南缘。该区以前寒武纪花岗片麻岩和片岩为基底,盖层为中生界与第三系的断陷盆地沉积,第四系为冲积相沉积(罗丹等,2009)。
所选样品新鲜,少数样品橄榄石斑晶发生局部伊丁石化蚀变。栖霞大方山霞石岩在镜下为斑状结构,斑晶主要为自形–半自形橄榄石,基质为橄榄石,钛磁铁矿、辉石以及方形霞石等,具有响岩结构,短柱状辉石充填在霞石之间(图2c~图2f)。无棣碣石山霞石岩为暗褐色,含有大量的橄榄岩捕虏体(图2b),捕虏体直径为1~2 cm,熔岩在镜下为斑状结构,斑晶为自形–半自形橄榄石斑晶和他形磁铁矿,基质由微粒矿物(橄榄石、钛磁铁矿)和玻璃质组成(图2g~图2j)。
笔者对采集自山东无棣碣石山以及大方山地区的12个霞石岩样品进行了详细的室内研究工作,对薄片进行镜下观察,开展全岩主量元素、微量元素分析测试,熔样及测试方法详见张珺杰等(2020)。
山东无棣碣石山霞石岩以及栖霞大方山霞石岩全岩主量元素、微量元素分析均在中国科学院海洋研究所大洋岩石圈与地幔动力学实验室完成。测试的主量元素氧化物包括:SiO2、TiO2、Al2O3、TFe2O3、MnO、MgO、CaO、Na2O、K2O、P2O5,主量元素粉末采用偏硼酸锂碱熔法熔样,并采用安捷伦 5100 型电感耦合等离子体光谱仪进行测试(ICP-OES)。
将样品放入 105 ℃烘箱中干燥 2 h,而后在铂金坩埚中称取约 50 mg 烘干样品粉末,加入约 250 mg 的偏硼酸锂,将这两种物质搅拌均匀。将盛有样品的铂金坩埚放入马弗炉中,在 1050 ℃的条件下加热 2 h,直至样品与偏硼酸锂混合物完全熔化。将铂金坩埚从马弗炉中取出并在 1000 ℃的本生灯上进一步加热,加热过程中不停晃动铂金坩埚,使熔融的混合物汇聚成一滴熔体。利用淬火原理,将样品熔体的液滴倒入 5% HNO3溶液中并在室温下溶解。最后,稀释样品溶液质量至称取样品质量的约 2000 倍,等待上机测试。
烧失量(LOI)分析过程如下:称取约 500 mg 样品,将样品放入马弗炉,1000 ℃条件下加热 30 min,样品取出后放入干燥器中冷却后再称取重量,加热前后样品的质量损失与样品质量的比值即为烧失量。
微量元素分析使用混合酸溶样法,流程为:将50 mg样品粉末放入Teflon溶样弹中,加入反王水和氢氟酸,将溶样弹放入高压釜中,在 190 ℃条件下加热溶解12 h。将样品溶液取出后,放在电热板上加热蒸干,随后加入1ml浓硝酸重复蒸干两次;依次加入1 ml 二次HNO3、4 ml MilliQ H2O,放入高压釜中, 190 ℃条件下加热2 h复溶;最后用2% HNO3稀释样品溶液质量至称样质量的2000倍,等待上机测试。样品测试使用安捷伦 7900型电感耦合等离子体质谱仪(ICP-MS)。分析测试过程中使用的标样为美国地质调查局(USGS)标准参考物质BCR-2 和 BHVO-2,测试结果和前人推荐的参考值基本一致(表1)。
山东霞石岩具有较低的SiO2和Al2O3 含量(表1),分别为40.64%~42.41%和9.60%~11.13%,TiO2含量为2.51%~2.83%、MgO含量为9.69%~13.50%、CaO含量为9.54%~12.98%,全碱含量Na2O+K2O值为5.43%~6.93%。在硅碱图上主要落在似长石岩、碱玄岩以及碧玄岩区域(图3),与前人的分析测试结果基本一致(罗丹等,2009;Zeng et al.,2010,陈立辉等,2012;何叶等,2019;2021)。在主量元素谐变图上,山东霞石岩SiO2与CaO、MnO、TFe2O3之间呈负相关关系,与P2O5、TiO2、Na2O、K2O含量呈正相关关系(图4)。
山东霞石岩的稀土元素含量较高1054×10−6~1613×10−6。在球粒陨石标准化稀土元素配分图上(图5a),轻重稀土元素分异明显 (La/Yb)N值为23.8~41.1,无明显负Eu、Ce异常。在原始地幔标准化微量元素配分图上(图5b),碣石山、大方山霞石岩表现出类似于洋岛玄武岩(OIB)的地球化学特征,即富集不相容元素,亏损K、Pb、Zr、Hf、Ti等,Hf/Hf*值为0.62~0.74、Ti/Ti*值为0.51~0.79,与已发表山东碣石山与大方山特征相似,但Ti/Ti*值更高。此外,碣石山以及大方山霞石岩Zr/Hf值为48.0~52.0,远高于原始地幔值 (Sun et al., 1989),所有的霞石岩都具有较高的Ce/Pb值(>21.0)。
幔源岩浆上升过程中,可能会受到陆壳混染或经历结晶分异特征。因此,在讨论源区特征之前,需探究岩浆是否代表原始岩浆的特征。碣石山、大方山具有较低的SiO2含量为39.2%~42.4 %,较高的MgO含量为8.0%~14.3%、CaO含量为8.4%~13.0%;具有较高的Ni 和Cr含量,含量分别为106×10−6~482 ×10−6和120×10−6~487×10−6,表明其幔源特征,而地壳混染不明显。碣石山、大方山霞石岩显示强烈的Pb、K负异常和Nb、Ta富集,与典型大陆地壳亏损Nb、Ta等高场强元素,具有明显的Pb正异常特征不同(Rudnick et al.,2014)。样品Ce/Pb值最低为14,Nb/U值最低为27.43,最高值为111.6,远高于大陆地壳(Ce/Pb=6.1,Nb/U=3.9)(Rudnick et al.,2014;Cai et al.,2021),表明样品陆壳混染可忽略不计。大方山霞石岩中发现有大量的地幔捕虏体,表明岩浆上升迅速,进一步支持较弱的地壳混染特征。因此,碣石山、大方山霞石岩未受到明显陆壳混染,这与前人对霞石岩的认识一致(罗丹等,2009;Zeng et al.,2010,陈立辉等,2012;何叶等,2019;Zeng et al.,2021;Zhang et al.,2023)。
值得注意,山东霞石岩样品Mg#与Cr、Ni,MgO与Al2O3之间具有一定相关性(图6b~图6d),表明存在橄榄石和单斜辉石分离结晶作用。碣石山比大方山更高的Mg#,可能表明大方山霞石岩经历了更高程度的岩浆演化。然而,大方山霞石岩没有明显的Eu异常,且MgO-CaO/Al2O3没有明显的负相关关系,因此,斜长石分离结晶不存在或程度较低(图6a)。鉴于样品可能经历不同程度的岩浆演化,笔者选取演化程度相对低的碣石山样品(JSS11-07)中Mg#最高的样品近似代表山东霞石岩母岩浆成分。
为进一步探究霞石岩源区特征,笔者根据实验岩石学所得的部分熔融分配系数(Zanetti et al., 2004; Adam et al., 2006),分别计算橄榄岩和辉石岩部分熔融形成的熔体SiO2含量,橄榄岩和辉石岩初始SiO2成分引自Workman et al. (2005)。模拟部分熔融形成的熔体元素含量过程根据Donnelly et al. (2004)。
$ C_{L}=C_{0}/(D_{0}+F(1-P)) $
$ P=p_{1}Kd_{1}+p_{2}Kd_{2}+p_{3}Kd_{3}… $
式中:CL代表元素在熔体中的浓度;C0代表该元素在未熔前的源岩中的浓度;D0为源岩总分配系数;F为部分熔融程度;P为源岩熔融掉的矿物组合的总分配系数;p1为熔体中矿物1的标准重量分数,Kd1为给定的某个元素在矿物1和熔体之间的分配系数,其他以此类推。值得注意的是,实际地质过程比模拟过程复杂得多,模拟过程可能与实际情况有一定差别,且初始成分、分配系数等的选择也会影响模拟结果趋势变化,导致计算结果与实际样品间部分元素含量差异。
结果表明,随着部分熔融程度的升高,SiO2含量增加;当部分熔融程度为0.1%时,两个源区产生的熔体SiO2含量分别为48.5%和50.4%(表2),远高于山东霞石岩SiO2含量。因此,橄榄岩或辉石岩部分熔融可能难以形成山东霞石岩母岩浆(以JSS11-07为例)。但已有实验表明,碳酸盐化橄榄岩/辉石岩部分熔融产生的熔体相对于非碳酸盐化橄榄岩/辉石岩,具有较低的SiO2,较高的CaO含量和Zr/Hf值(Wyllie et al.,1976;Wendlandt et al.,1980;Dasgupta et al.,2006;Rajdeep et al.,2007;Dasgupta et al.,2009;程志国等,2016),可能与山东霞石岩母岩浆特征相似。因此,笔者基于实验岩石学数据,分别计算含碳酸盐岩橄榄岩、辉石岩发生不同程度部分熔融形成的熔体成分。计算结果表明:当15%左右碳酸岩+橄榄岩中或20%左右碳酸岩+辉石岩源区发生部分熔融产生的熔体与山东霞石岩SiO2含量近似(表2)。但是,已有的实验数据表明,碳酸盐化橄榄岩部分熔融形成的TiO2含量低于山东霞石岩TiO2含量(Guzmics et al.,2012)。此外,当碳酸盐化橄榄岩/辉石岩部分熔融产生主量元素含量范围与山东霞石岩一致的初始熔体成分时,二者的微量元素相差甚远(图7)。因此,碳酸盐化橄榄岩/辉石岩部分熔融产生的熔体可能经历了其他过程,才能形成山东霞石岩。
在许多火成岩杂岩中碱性硅酸盐岩都与碳酸岩伴生产出,如非洲部分地区霞石岩。已有众多明确的证据表明,碳酸岩和硅酸岩之间存在成因关系(Lee et al.,1997;Woolley et al.,2008;Brooker et al.,2011;Guzmics et al.,2012)。霞石岩和碳酸岩被认为可能是共同的母岩浆中产生的两种熔体液态不混溶的结果。自坦桑尼亚Oldoinyo Lengai喷发期间形成的钠质碳酸岩熔岩流中发现存在硅酸盐碎屑开始,这一认识已引起普遍关注,并被用来解释霞石岩和碳酸岩之间的共生关系:即原生碳酸盐化硅酸盐岩浆可能分离成两个共存但互不混溶的熔体,一个是最终形成碳酸岩的碳酸质熔体,另外一个是最终形成霞石岩的硅酸岩熔体。实验岩石学同样在硅酸岩熔体中发现类似的淬火碳酸盐液滴(Wyllie et al.,1998;Guzmics et al.,2012),证实液态不混溶过程的存在,且一致认为富含碳酸盐的地幔熔体是在相对低压(1~1.7 Gpa)的地壳环境下形成不混溶的熔体(Koster et al.,1968;Lee et al.,1997;Kjarsgaard et al.,1998;Guzmics et al.,2012)。笔者推断山东霞石岩可能经历类似的过程,根据不混溶实验岩石学得出的分配系数D碳酸岩/硅酸岩,计算碳酸岩熔体的地球化学成分,进而把霞石岩熔体(JSS11-07为参考)和计算所得的碳酸岩熔体混合,反推原始母岩浆成分。定量计算结果表明,随着硅酸岩熔体含量的增加,原始母岩浆的SiO2由4.19%增加到41.86 %,其他主量元素含量及变化规律(图8,表3),分配系数引自(Martin et al.,2013)。
根据上述原始母岩浆的SiO2成分,结合表2,得出10%~80%碳酸岩+橄榄岩或20%~90%碳酸岩+辉石岩源区发生一定程度部分熔融产生的熔体组成,可能代表山东霞石岩原始母岩浆成分。为验证这一推论,下文将进一步开展微量元素定量计算。
为进一步探究源区特征,笔者选取不同源区组成定量模拟计算不同程度部分熔融的熔体组成。计算结果表明:碳酸岩+辉石岩部分熔融产生的微量元素特征与根据微量元素数据反算得出的液态不混溶之前初始熔体成分差别较大,而10%~40%碳酸岩+橄榄岩发生3%~5%低程度部分熔融形成的熔体与初始熔体成分相似(图9)。因此,笔者认为母岩浆是10%~40%碳酸岩+橄榄岩发生低程度(3%~5%)部分熔融的结果,进一步印证上文根据主量元素计算得出的关于源区组分的推测。相较于部分熔融形成的熔体,初始熔体具有明显的Sr正异常,可能是由于母岩浆含有较多的方解石。
山东无棣碣石山和栖霞大方山均未发现与霞石岩伴生的碳酸岩,与上述东非地区霞石岩与碳酸岩伴生现象不一致,且山东霞石岩未呈现出与高温高压实验类似的碳酸质球粒或包体。此外,碳酸岩与霞石岩伴生常出现在张性环境,如东非裂谷,极少出现在俯冲环境(Ray et al.,1999,万欣,2015),笔者总结了以下几点可能原因:①碳酸岩熔体低密度、低粘度的物理性质,导致其在不利于喷发的环境下迅速弥散,热量迅速降低,而居留在地壳之中。②碳酸岩熔体向上运移过程中,由于压力降低,碳酸盐化矿物发生分解(Canil et al.,1990);或碳酸盐熔体在到达地表之前与周围矿物发生脱碳酸盐化反应,最终转化为CO2(Wyllie et al.,1975;Wallace et al.,1988;Dalton et al.,1993)。③碳酸岩熔体与周围岩石发生交代反应,最终转变成其他成分固定在一定深度范围内,例如碳酸岩熔体-橄榄石相互作用,碳酸岩熔体作为交代介质被上覆橄榄岩进一步固定(王静等,2023)。显生宙以来,华北克拉通东部经历多期次俯冲事件,山东位于华北克拉通东南缘,是典型的挤压环境(汪在聪等,2023),可能是研究区未发现与霞石岩伴生的碳酸岩的原因。
金伯利岩作为地幔来源的富水、偏碱性的超基性岩浆,也常与碳酸岩和霞石岩伴生,三者被认为存在成因联系(Zanetti et al., 2004; Agashev et al., 2008)。金伯利岩携带的地幔包体可以提供深层地幔的信息,且金伯利岩是赋存金刚石的重要岩石,具有重要的经济价值,其来源及成因一直是地质学的研究重点(Haggerty et al., 1994)。目前,关于金伯利岩的成因及来源存在不同认识:①来自碳酸盐化硅酸盐熔体的液态不混溶作用(Koster et al., 1968; Lee et al., 1997; Kjarsgaard et al., 1998; Guzmics et al., 2012) 或者分离结晶作用(Wyllie et al., 1976; Harmer et al., 1998)。②碳酸盐化地幔部分熔融的结果(Zanetti et al., 2004; Nowell et al., 2004; Sparks et al., 2006; Coe et al., 2008)。
定量计算结果发现,当硅酸盐物质含量为30%时,初始熔体与金伯利岩的SiO2含量相似。为此,笔者将西伯利亚乌达奇纳亚东部金伯利岩与计算获取的碳酸岩化橄榄岩部分熔融形成的初始熔体的主微量元素数据进行对比(表4,图10),其中西伯利亚乌达奇纳亚东部金伯利岩样品为新鲜未受混染的样品(Kamenetsky et al., 2007; Yumi et al., 2021)。
通过对比发现,计算的部分霞石岩初始熔体主、微量元素组成与金伯利岩主、微量元素特征相似,都具有低SiO2、TiO2和Al2O3含量的特征;显示Zr、Hf负异常,表明笔者研究的霞石岩对应的初始熔体与金伯利岩具有相似性。但相较于霞石岩初始熔体,金伯利岩具有更高的MgO,更低的CaO(图8),霞石岩演化过程中存在单斜辉石和橄榄石分离结晶,可能是初始熔体相较于金伯利岩岩浆具有较低MgO含量的原因,而低CaO可能表明金伯利岩形成过程中还存在较小程度斜长石的分离结晶。笔者推测金伯利岩岩浆很可能代表部分霞石岩–碳酸岩组合的母岩浆,但更多细致、系统的对比研究工作有待进一步开展,以期为认识地幔岩浆和源区性质提供更多信息。
(1)山东无棣碣石山以及栖霞大方山霞石岩具有高Zr/Hf值,K、Zr、Hf、Ti的负异常,较低SiO2含量,以及较高MgO、CaO、Ni、 Cr含量,Mg#与Cr、Ni之间存在相关性,表明碣石山、大方山霞石岩存在橄榄石、单斜辉石的分离结晶,且大方山霞石岩比碣石山的霞石岩演化程度更高。
(2)定量计算结果显示,碳酸盐化橄榄岩/辉石岩部分熔融与山东霞石岩部分主量元素特征吻合,但不能满足其微量元素特征,母岩浆需经历液态不混溶,分别形成霞石岩熔体和碳酸岩熔体。
(3)通过实验岩石学数据以及霞石岩主、微量元素数据,反算霞石岩液态不混溶之前源岩熔体组分由10%~40%碳酸岩+橄榄岩经历约3%~5%的部分熔融形成。
(4)金伯利岩与山东霞石岩液态不混溶之前的初始熔体主、微量元素特征相似,推测金伯利岩岩浆很可能代表霞石岩–碳酸岩的母岩浆,但更多细致、系统的对比研究工作有待进一步开展,以期对地幔源区性质有更准确、全面的理解。
