Data underlying the article: A geometrical method for quantifying mixing fractions in three-component groundwater mixing: experimental evidence from Ferrarelle aquifers

In this file the chemical analyses of groundwater samples from Ferrarelle aquifers (Riardo plain, southern Italy) and related data elaborations are reported. The data elaborations consist in correlations computing and fractions estimation of the investigated groundwater three component mixing. The dataset consists in four sheets: 1) "Row data" sheet reports the monthly chemical analyses of sampled groundwater from each well analyzed for major ions, minor and trace elements (IC and ICPMS analyses). 2) "correlation matrix" sheet reports the correlations computed among all the analyzed chemical variables. 3) "algebraic mixing computations" reports the computing of three component mixing fractions through the traditional mass balance equations and the related uncertainties. 4) " EMMA mixing computations" reports the computing of three component mixing fractions through EndMember Mixing Analysis (EMMA method) and the related uncertainties.

本文件收录了采自意大利南部里亚尔多平原费拉雷莱含水层（Ferrarelle aquifers）的地下水样品化学分析结果，以及相关数据处理成果。本次数据处理包含两项内容：一是相关性计算，二是对研究区地下水三组分混合过程的占比进行估算。本数据集包含四个工作表：1. 「原始数据（Row data）」工作表：收录了各监测井地下水样品的月度化学分析数据，涵盖主要离子、微量与痕量元素的检测结果（采用离子色谱（IC）与电感耦合等离子体质谱（ICPMS）完成分析）。2. 「相关性矩阵（correlation matrix）」工作表：收录了所有被测化学变量间的计算相关性结果。3. 「代数混合计算（algebraic mixing computations）」工作表：基于传统质量平衡方程，完成三组分混合占比的计算，并给出了相关不确定度。4. 「EMMA混合计算（EMMA mixing computations）」工作表：采用端元混合分析（EndMember Mixing Analysis, EMMA）方法完成三组分混合占比的计算，并给出了相关不确定度。
