摘要:
黑尖山铁矿床是新疆东天山阿齐山—雅满苏成矿带中典型的海相火山岩型铁矿床。黑尖山矿床围岩安山质熔岩中发育大量不规则的富铁团块，可分为钠长石磁铁矿型、钠长石钾长石磁铁矿型、钾长石磁铁矿型、绿帘石磁铁矿型和石英磁铁矿型5种类型，可能代表了在岩浆-热液成矿过程中不同演化阶段的产物，对黑尖山铁矿床成矿过程及形成环境有指示意义。本文对上述5类富铁团块中的磁铁矿进行了主量元素分析，为了精确地测出磁铁矿中铁的总量，采用差分法加入不确定的O含量，并加以ZAF矩阵校正。对比5类富铁团块中磁铁矿Ti含量，钠长石磁铁矿型最高、钠长石钾长石磁铁矿型和钾长石磁铁矿型较高、绿帘石磁铁矿型和石英磁铁矿型最低，且Ti含量与Fe含量为正相关关系；绿帘石磁铁矿型和石英磁铁矿型富铁团块Fe含量特征与矿石中磁铁矿Fe含量相近。上述特征表明钠长石磁铁矿类型是残余富铁熔体中最早的结晶产物，钠长石钾长石磁铁矿和钾长石磁铁矿类型具有岩浆热液转变的特征，而绿帘石磁铁矿和石英-磁铁矿类型则是受热液完全交代的产物，说明矿床形成于岩浆-热液成矿作用。各类富铁团块内磁铁矿的Fe含量均大于相对应蚀变环边磁铁矿的Fe含量，表明富铁岩浆结晶与热液活动分异同期发生。
Abstract:The Heijianshan iron deposit represents a typical submarine volcanic rock-hosted deposit of the Aqishan-Yamansu ore belt in Eastern Tianshan Mountains. Abundant irregular iron-rich agglomerates are developed in the brecciated andesite lava (wall rock), and they can be subdivided into five types, i.e., albite-magnetite type, albite-K-feldspar magnetite type, K-feldsparmagnetite type, epidote-magnetite type and quartz-magnetite type, likely representing evolving products of the magmatic-hydrothermal ore-forming process, which can constrain the ore-forming process and metallogenic environment of the Heijianshan iron deposit. Magnetite compositions of the five types of agglomerates were analyzed using electron microprobe analysis. For the purpose of obtaining precise Fe content, the content of undetermined O was added by difference method and the ZAF matrix correction was conducted. The Ti values of the five types of agglomerates display a positive relationship with the Fe values. Magnetite of the albite-magnetite type has highest Ti content, the albite-K-feldspar magnetite and the K-feldspar-magnetite types show medium Ti content, whereas the epidote-magnetite and quartz-magnetite types are characterized by the lowest Ti content. Also, the Fe content of the epidote-magnetite and the quartz-magnetite types is similar to that of the ores. These features indicate that the albite-magnetite type seems to have been the earliest crystallization product from a residual iron-rich melt, the albite-K-feldspar-magnetite and K-feldspar-magnetite types display features of magmatic-hydrothermal transition, whereas the epidote-magnetite and quartz-magnetite types represent products of hydrothermal alteration. The Fe content of magnetite of each type of agglomerate is higher than its content of the corresponding alteration zone, suggesting a simultaneous relationship between the crystallization of iron-rich agglomerates and hydrothermal activities.

1. 引言
砷(As)在自然界普遍存在，是国际癌症研究机构(IARC)列出的第Ⅰ类明确致癌物(WHO, 2011；Shahid et al., 2018)。饮用水砷浓度最敏感的毒性阈值尚未确定，世界卫生组织推荐的饮用水砷浓度限值为10 μg/L(WHO, 2011)。美国环境保护署(EPA)和国家研究委员会(NRC)指出，长期饮用浓度低至5 μg/L甚至3 μg/L的水可能会对人类健康造成慢性影响，引发癌症(Taheri et al., 2017)。饮用高砷地下水是人类遭受砷暴露风险的主要途径，全球有超过1亿人承受高砷地下水的暴露风险，其中中国有1900万(Duan et al., 2017; Li et al., 2017；Cao et al., 2018；Shahid et al., 2018)。
高砷地下水在全球分布广泛，南亚、东南亚是地下水砷污染的典型地区，已经开展过深入而广泛的地球化学研究，解析高砷地下水的形成演化过程，追溯砷的来源及其溶出释放机制(Tang et al., 1996；Wang et al., 1998；Deng et al., 2009; Xie et al., 2012；Li et al., 2013；Gan et al., 2014；Hu et al., 2015；Gupta et al., 2017；Zhang et al., 2017；Han et al., 2017；Li et al., 2018；Gillispie et al., 2019；Gao et al., 2020)。含砷矿物氧化溶解及还原活化是高砷地下水形成的主要机制(Gupta et al., 2017; Zhang et al., 2017; Shahid et al., 2018; Gillispie et al., 2019; Stopelli et al., 2020)。中国高砷地下水主要分布在大同盆地、江汉平原、河套盆地、银川盆地等内陆平原区；淮河流域是中国新发现的高砷地下水集中分布区，高砷地下水分布范围广，影响人口众多。根据2010年代开展的淮河流域地下水分析数据统计预测，淮河流域大部分地区的砷暴露风险概率大于0.4，统计发现流域内各村庄监测水井As浓度超过10 μg/L的比例达17%，最高检测值为620 μg/L(Li et al., 2017)。
高砷地下水的形成是在水岩相互作用过程中多因素共同作用的结果。淮河流域富砷地下水砷污染系原生成因，以前的研究工作主要集中在地下水As的水文地球化学分布、饮水型砷中毒地方病的地理分布等方面(Zhang et al., 2010；Chen et al., 2013; Li et al., 2017)。淮河流域高砷地下水的研究程度低，缺乏对高砷地下水的形成过程及其影响因素的深入解析，高砷地下水的形成演化机制不明。本次研究选择淮河平原代表性的高砷地下水小尺度流场，针对以往研究的薄弱环节，运用地下水水文地球化学分析方法，主要研究目标为：(1)分析典型高砷地下水的水文地球化学特征，评估其污染风险；(2)解析高砷地下水的形成演化过程；(3)追溯砷污染物的来源及溶出释放过程。开展高砷地下水的形成演化过程研究，为淮河流域高砷地下水的治理与公共健康风险控制提供科学依据。
2. 研究区概况
淮河流域地处中国东部，流域西起桐柏山、伏牛山，东临黄海，南以大别山、江淮丘陵、通扬运河及如泰运河分界，北以黄河、泰山为界与黄河流域毗邻，地理坐标：111°55′~121°25′E，30°55′~36°36′N，面积为27万km2。该流域处于中国南北气候过渡带，属暖温带半湿润季风气候区，年平均气温11~16℃。其地质构造上位于华北板块、扬子板块、秦岭造山系3个构造单元的交接地带(Zhang et al., 2015) (图 1)。

Geological background, sampling sites and hydrogeological profile of Taihe County of Anhui Province in Huaihe River Basin研究区安徽省太和县位于淮河流域中部，以冲积平原地貌为主，海拔高程一般15~50 m，地势由西北向东南微倾。研究区分布最广的地下水类型为松散岩类孔隙水，水文地质分区划分为淮河中游淮北冲积平原区。自新近纪(23 Ma)以来，淮河流域形成了巨厚的新近系、第四系松散沉积物，为区域地下水的形成与分布提供了良好的水文地质条件。研究区地下水系统自上而下划分为浅层、中深层、深层含水系统(Li et al., 2018)。浅层地下水赋存于50 m以浅的全新统、上更新统地层，与大气降水、地表水关系密切，地下水埋深一般为2~4 m，均在极限蒸发深度以内，蒸发是浅层地下水的主要排泄途径。中深层地下水赋存于50~150 m的中、下更新统地层，深层地下水主要赋存于150~500 m的新近系(图 1)。由于中、深层地下水埋藏较深(埋深大于50 m)，含水层之间有着黏性土层相隔，不能直接接受大气降水的补给，径流缓慢，人工开采是深层地下水的主要排泄途径。
3. 调查研究方法
太和县是淮河平原典型的高砷地下水分布区(图 1)，本次研究选择太和县马集镇及相邻区的高砷地下水小尺度流场为天然实验场，采集测试地下水样品。本次研究采用精度为1 km×1 km(局部1 km×0.5 km)的近似网格法布设采样点。本次研究于2019年5、9月采集样品，共采集地下水样64件。采集的地下水样品，主要取自研究区井深不到50 m的浅井，水位埋深4~50 m，含水层为第四系砂层、细砂层、粉砂层。
地下水样品水化学分析了As、K+、Na+、Ca2+、Mg2+、Cl-、SO42-、HCO3-、F-、Br-、总碱度和总酸度。阳离子(Na+, K+, Ca2+, Mg2+)采用电感耦合等离子体发射光谱法(ICP-OES)测定，阴离子(HCO3-, SO42-, Cl-, F-, Br-)用离子色谱法测定，总碱度、总酸度采用酸滴定法测定，地下水As浓度测试采用荧光光谱仪(AFS-820，中国)，As检出限为0.05 μg/L，精密度＜1.0%。样品测试分析由中国地质调查局南京地质调查中心实验测试中心完成。研究区地下水化学分析结果见表 1。

根据热力学原理，水岩反应中矿物的溶解与沉淀由各种矿物在地下水中的饱和指数(SI) 决定，利用SI可以识别水质和水化学演化过程(Zhu et al., 2011；Han et al., 2014；Taheri et al., 2017)。SI的数学表达式为:
其中IAP是离子活性积，Ks是矿物的平衡常数。SI＜0、SI = 0、SI＞0分别为矿物处于溶解、平衡、沉淀阶段的热力学判据，通常认为0.5＞SI＞-0.5为近饱和状态。
地下水化学分析以SPSS 19.0为平台对数据进行描述统计、相关分析、回归分析，以Phreeqc 3.40为平台选择确定矿物相，计算矿物饱和指数，专题图以Coreldraw X4、AquaChem 3.70为平台制作。
4. 结果与分析
4.1 地下水质量评价
根据地下水化学测试分析结果，依据国家地下水质量标准GB/T 14848-2017分类标准(MLR，2017)，地下水中As、Cu、Mo、Ba、Na+、Cl-、SO42-、HCO3-、CO32-、NO3-、NO2-、F-、COD、I、TDS、Mn、HBO2等的均值、标准差与质量分类见表 1。影响太和马集研究区松散岩类孔隙水水质的主要无机组分是砷、钡、钠、氯、氟、碘、锰、硝酸盐、硫酸盐、硼、溶解性总固体，其中砷、氟、锰、钠、硼是最主要影响因子，单项指标超过地下水质量Ⅲ类标准的样品比例均超过50%(表 1、表 2)。

依据世界卫生组织推荐的饮用水质量标准(WHO, 2011)，影响研究区地下水水质的主要因素是As、F浓度。研究区浅层地下水砷浓度为(5.75±5.42) μg/L，呈现明显的空间变异性；超过世界卫生组织饮用水推荐准则值(10 μg/L)样品比例为23%，呈现高暴露风险。地下水氟浓度为(1.29±0.40) mg/L，超过推荐限值(1.5 mg/L)样品比例达31%。
4.2 地下水离子浓度与水化学类型
本次研究采集分析的地下水均为浅层孔隙水，含水岩组为全新统和上更新统含水岩组。根据水化学分析结果，研究区浅层地下水的总溶解固体(TDS)浓度为(719.29±310.20) mg/L，其中大部分样品为低盐度淡水(＜1000 mg/L)，26%在微咸水(1000~3000 mg/L)范围内。地下水的化学成分受主要离子(SO42-、Cl-、HCO3-、Na+、Ca2+、Mg2+)控制。阴离子成分以HCO3-为主，SO42-和Cl-次之，浓度分别为(617.93±220.25)、(83.73±73.09)、(54.03±58.81) mg/L。阳离子以Na+为优势离子，其次为Ca2+、Mg2+，浓度分别为(186.04±120.17)、(46.17±27.91)、(39.48±12.39) mg/L。
研究区测试样品总碱度(516±169) mg/L，总酸度(20.00±4.63) mg/L，地下水呈碱性。测试样品总碱度与HCO3-浓度极显著正相关，相关系数R=0.997(P≤0.01)，故水样中总碱度表现为HCO3-碱度，总碱度大小总体上反映了HCO3-含量的大小。高砷地下水总碱度主要分布在400~700 mg/L(图 2)，研究区碳酸盐岩矿物风化作用和离子交换反应升高了地下水的碱度。

4.3.1 蒸发浓缩作用
Cl和Br也是地下水中普遍存在的溶质，由于Cl、Br在天然水中的保守行为和高溶解度，离子交换反应与矿物表面吸附等过程不能显著改变Cl和Br的浓度。岩盐(NaCl)矿物结构中不含较大的Br离子，其Cl/Br比值一般为104~105(摩尔比)，岩盐溶解随着氯离子浓度的增加将产生Cl/Br比值的快速增加；相比之下，地下水的蒸发过程可以改变地下水中Cl和Br的绝对浓度，但不会改变地下水岩盐饱和之前的Cl/Br比值。因此应用Cl、Br及Cl/Br比值可以识别区分地下水的溶解、蒸发等演化过程(Cartwright et al., 2006；Deng et al., 2009；Xie et al., 2012；Xing et al., 2013；Han et al., 2014；Taheri et al., 2017)。
研究区测试样品的Cl-浓度范围0.70~210 mg /L，均值(54.03±58.81) mg/L，Br-浓度范围为10.7~324 μg/L，均值(104±87.9) μg/L。Cl-浓度与Br-浓度显著正相关，相关系数0.75(P≤0.01)。样品的Cl-、Br-浓度较低，Cl/Br(mol)均值为1097±1044，比值变化范围51.0~4603。样品中大部分的Cl/Br比值超过600，显示显著的空间变异性；As超标地下水(＞10 μg/L)的Cl/Br比值范围544~3093，均值993。测试样品Cl/Br比值最高值超过4600，地下水Cl浓度不超过6 mmol /L，地下水溶解少量的岩盐是Cl/Br比值快速增大最可能的机制，较大的Cl/Br比值变化范围反映出各测试样品岩盐溶解量的不同。Cl/Br比与Cl浓度之间的关系(图 4)表明，蒸发作用、岩盐溶解作用是控制浅层地下水分布的主导过程，高砷地下水Cl/Br比值随Cl浓度的增加而相对不变，说明高砷地下水更大程度受到蒸发作用的影响。

Ca/Na、Mg/Na、HCO3/Na(mol)比值可以表示地下水矿化度的强弱，也可以得到地下水来源及水质演化的相关信息，在一定程度上为区域水文地球化学演化过程提供判断依据(Zhu et al., 2011; Liu et al., 2018)。从研究区地下水Mg /Na-Ca/Na、HCO3/Na-Ca/Na关系图(图 5)可知，随着Ca/Na比值的增大，地下水的Mg /Na、HCO3/Na比值逐渐增加。地下水主要阳离子浓度比值主要分布于蒸发盐矿物溶解与硅酸盐矿物风化作用之间，少部分分布于硅酸盐矿物风化作用与碳酸盐矿物溶解作用之间，表明研究区地下水受到蒸发盐溶解、硅酸盐风化、碳酸盐溶解等过程的共同影响。高砷地下水的离子比值主要分布于蒸发盐矿物溶解与硅酸盐矿物风化作用之间，显示高砷地下水更大程度受到蒸发盐溶解与硅酸盐矿物风化过程的影响。

Na/Cl比值(mol)是表征地下水中Na+富集程度的一个水文地球化学参数，可以用来反映离子交换程度(Xing et al., 2013；Han et al., 2014；Yang et al., 2016；Taheri et al., 2017)。淮河流域属于干旱—半干旱地区，蒸发作用强烈，导致岩盐在沉积层累积，岩盐溶解是平原盆地区地下水中Na+和Cl-的主要来源之一。如果岩盐溶解为Na+与Cl-的主要来源，则Na/Cl(mol)-的比值应为1∶1，高于此比值的Na+则可能有其他来源。本次研究全区采集地下水样Na/Cl比值为9.63±57.4，绝大部分样品远大于1∶1，呈现显著的空间变异性，Na/Cl比值随Cl浓度的增加呈下降趋势；高砷地下水(10＞As≥5 μg/L)、污染地下水(As≥10 μg/L)的Na/Cl比值分别为43.1±85.1、15.7±16.0，全部位于岩盐溶解线上方(图 6)。由此推断，研究区地下水的Na+并不仅仅来源于岩盐溶解，地下水总体上可能经历强烈的阳离子交换作用，而且高砷地下水的离子交换作用更为显著。

水岩相互作用控制着地下水中主要离子浓度及其赋存状态。本次研究利用PHREEQC 3.7计算矿物饱和指数，结果表明：近饱和矿物方解石(0.41)、文石(0.26)、菱镁矿(0.04) 的SI值接近0，处于准平衡状态；未饱和矿物岩盐(-6.52)、石膏(-1.99)、硬石膏(-2.23)、萤石(-1.02)的SI值小于-0.5，表明存在岩石溶解的趋势；白云石(0.70) 的SI大于0.5，存在化学沉淀的趋势(表 3)。地下水中Cl-、F-、SO42-部分源自岩盐、萤石及石膏、硬石膏矿物的溶解释出。

在自然环境pH、Eh条件下，砷元素主要以无机氧化态As(Ⅴ)和还原态As(Ⅲ)元素价态存在。沉积物(土壤)中含砷矿物通常以砷酸盐、亚砷酸盐和硫化物等矿物相存在，在还原条件下，砷黄铁矿是砷的稳定宿主，其伴生砷与地下水砷分布高度相关(Hu et al., 2015; Taheri et al., 2017; Duan et al., 2017; Zhang et al., 2017; Shahid et al., 2018; Gillispie et al., 2019)。地下水动态、氧化还原电位(Eh)、酸碱度(pH)的变化影响沉积物砷的吸附-解析过程，进而影响水体砷的浓度，高pH、低Eh还原条件促进沉积物中砷的解吸和溶解进入地下水而在溶液中积累(高存荣等, 2010; 王杰等, 2015; Duan et al., 2017; Taheri et al., 2017; Zhang et al., 2017; Gillispie et al., 2019)。
地下水中的SO42-可能源自石膏溶解与硫化物氧化，全区地下水SO42-/Ca2+ (mol) 比值为0.76，地下水的SO42-不仅仅源于石膏矿物的溶解，还有硫化物的氧化。测试样品中的As和SO42-浓度之间正相关(相关系数R=0.584)。分析样品中As＜3 μg/L、3 μg/L≤As＜5 μg/L、5 μg/L≤As＜10 μg/L与As≥10 μg/L地下水的SO42-浓度均值分别为0.74、1.09、0.92与0.93 mmol/L，高砷地下水呈现相对高的硫酸盐浓度。
经X射线衍射物相分析，淮河流域浅层(0.2~1 m)沉积物主要矿物成分为石英、钾长石、方解石和黏土矿物，含量分别为47.1%、3.79%、8.27%和33.4%。部分样品中含有少量黄铁矿和菱铁矿，含量分别为2.5%和47.1%，未检测到赤铁矿，反映还原性地下水环境。据地下水化学数据与表层沉积物物相分析结果推测淮河流域沉积物中砷在还原条件下可能以含砷硫化物相存在，由于长期大量开采地下水，地下水流系统环境改变，破坏了含水层固液相动态交换的平衡，触发As从固相释放到地下水中。碳酸盐矿物的溶解通常会增加碱度(pH)值，在高pH条件下，含砷硫化物的氧化速率增加，地下水SO42-浓度增高，促进As向水体的释出。pH值的增大也促进As从金属氧化物(Fe、Mn)中解析从而增加水中As浓度(Duan et al., 2017; Taheri et al., 2017; Zhang et al., 2017; Gillispie et al., 2019)。因此推测含水层沉积物含砷矿物氧化溶解与还原活化是导致原生砷向地下水释出的主要过程。研究区地下水表现出的高矿化度和强烈蒸发作用可能与农业灌溉有较大关系，含水层中原生的矿物组分是造成高砷水的最主要原因。另外，高强度的深层地下水抽取灌溉也可能是导致的高砷水进入浅水含水层的原因之一。
5. 结论
高砷地下水的形成是多因素综合作用的结果，是一个复杂的水文地质过程。高砷地下水的形成是含砷矿物集聚、固相砷的溶解析出及富集砷的水文地质条件等在水岩相互作用过程中多因素综合作用的结果。本次研究选择流域内典型的高砷地下水小尺度流场为天然实验场，解析高砷地下水的形成演化过程，追溯砷的来源及其溶出释放机制。
(1) 研究区地下水砷含量为(5.75±5.42) μg/L，具有明显的空间变异性，超过世界卫生组织饮用水推荐准则值的测试样品比例为23%，呈现高暴露风险，饮用高砷地下水可能是威胁人类健康的主要途径。
(2) 根据水化学成分解析，研究区地下水经历蒸发作用、岩盐溶解、水岩相互作用等过程的共同影响。高砷地下水的化学类型主要为HCO3-Na型，高砷地下水更大程度受到蒸发作用、阳离子交换作用的影响。
(3) 研究区高砷地下水系原生成因，高砷地下水的As源自含水层沉积物原生砷的溶出释放。碱性环境下，含水层沉积物含砷矿物氧化溶解与还原活化可能是高砷地下水形成的主要机制。
