<b>Supporting Information for Characteristics of the river sediments originating from the Zhangguangcai Ridge, NE China and Their Geological Significance</b><p dir="ltr">河流沉积物因其对环境变化和快速物质更替的敏感响应，尤其是中小型河流（如中国东北松花江支流）是解读源汇过程和区域地质演化的重要档案。本研究聚焦于松花江四条支流的河流沉积物：阿诗河（AR）、拉林河（LR）、马义河（MYR）和牡丹河（MDR）。对这些河流沉积物进行了粘土矿物、地球化学、重矿物及碎屑锆石U-Pb地质年代学分析，以阐明其来源特征和风化过程。沉积物中的粘土矿物组合以伊利石为主（41.2%–64.5%），其次是高岭土和蒙脱石。伊利石-蒙脱石混层矿物的广泛分布表明源区化学蚀变有限且化学风化作用较弱。粉砂组分（<63微米）的地球化学成分在母岩中表现出长英质特征，但粘土组分（<2微米）则不表现出类似特征。与粘土组分相比，粉砂组分表现出较低的成熟度和更少的回收特征。值得注意的是，粉砂和粘土组分反映了明显不同的化学风化程度。粉砂分数的化学变质指数（CIA）值表明化学风化程

Supplementary Information/Data Tables: A snapshot of microplastic distributions across discrete sedimentary environments of an Arctic valley-fjord system<p dir="ltr">An understanding of patterns of microplastic loss and sedimentation is important for identifying microplastic hotspots and their evolution. Here we show accumulation of microplastics in an anthropogenically impacted glacier-valley-fjord system in Svalbard, Norway. Microplastics were found in the snowpack overlying the glaciers (1.2 ± 1.6 n L<sup>-1</sup>), inside an englacial meltwate
