Porphyry copper deposits（PCDs） supply the majority of the world's copper（Cu） as well as significant amounts of molybdenum（Mo） and gold（Au）. The formation of these deposits is controlled by a variety of geological factors, among which the magmatic oxidation is one of the focuses of current research. This study investigates the redox characteristics of arc magmas by analyzing the ratio of vanadium（V） to scandium（Sc） and its correlation with the oxygen fugacity （fO2） of magmas from arcs of various crustal thicknesses globally. We compiled an extensive dataset of published V/Sc values and studied the partition coefficients of Vand Sc between minerals and silicate melts across various magmatic environments. The results demonstrate that fractional crystallization of magnetite markedly reduces V/Sc values of the residual melt. Furthermore, magnesium number（Mg#） at the onset of magnetite fractionation is strongly positively correlated with fO2of the equilibrium magma. Based on this,the oxidation of arc magmas from different crustal thicknesses can be evaluated. The result suggests that magmas generated in crusts thicker than 20 km tend to be more oxidized with increasing crust thickness. This trend is attributed to enhanced intracrustal differentiation processes involving garnet and amphibole, particularly in mature island and continental arcs. In contrast,magmas in thinner arc crusts（<20 km）, which are significantly influenced by subducted slab materials, display higher oxidation states than most of their thicker crust counterparts. These findings suggest that both subduction dynamics and crustal thickness play a vital role in determining the oxidation state of arc magmas and, consequently, their capacity to generate PCDs. Highly oxidized, primitive arc magmas are less favorable for PCD formation due to that they tend to experience magnetite fractionation and thus sulfide saturation in the early stage of magma evolution, a process leading to copper depletion.

目的研究应用磁共振Dixon技术对全肝进行无创脂肪定量测量的临床价值。方法收集94例患者临床资料。使用Siemens 3.0T Magnetom Verio磁共振机,将T1WI_VIBE_DIXON序列采集的全肝数据导入MATLAB软件,利用插入的脂肪定量后处理算法计算,生成脂肪体积分数图。由同一位磁共振诊断医师以横轴位肝门层面为中心层面,沿肝脏边缘勾画出全肝轮廓为感兴趣区,并在中心层面上下连续取3个层面进行测量,将所得7个测量值的中位数作为最终结果。所有被检者的磁共振检查与肝穿刺活检术相隔时间在1周内,由同一位病理学医师做诊断并记录脂肪变肝细胞的百分数。结果以肝穿刺活检术的脂肪变病理分级结果为金标准,94例样本分为轻度组45例,中度组28例,重度组21例,各组间的Dixon全肝脂肪定量结果有显著差异(X^2=75.975,P<0.001)。同一样本的Dixon全肝脂肪定量数值<肝穿刺脂肪定量数值(Z=-4.368,P<0.001),但两者呈显著正相关(r=0.824,P<0.001)。应用Dixon技术测量全肝脂肪体积分数进行分级诊断时,诊断"轻度"时灵敏度、特异度、Youden指数、阳性预测值和阴性预测值分别为88.90%、100.00%、88.90%、100.00%和90.74%;诊断"中度"时分别为96.40%、89.39%、85.79%、79.41%和98.33%;诊断"重度"时分别为90.48%、98.63%、89.11%、95.00%和97.30%。结论磁共振Dixon全肝脂肪定量与肝穿刺活检脂肪定量的结果一致性较好,两者均能反映脂肪肝的严重程度。应用无创的磁共振全肝脂肪定量代替有创的肝穿刺活检脂肪定量,有一定的临床推广价值。
