Electronic probe analyses were performed on 343 and 406 sedimentary amphibole single-mineral samples extracted from five sampling points in the Huanghe River estuary and six in the Changjiang River estuary. The profiles of amphibole single-mineral major elements were determined for the two rivers using these samples. The cation coefficients and related parameters of 749 amphiboles were calculated based on 23 oxygen standards, and their crystal structure molecular formulae and related characteristic crystallochemical values were determined. The results show that the sedimentary amphiboles of the two estuaries belong to the calcic amphibole subgroup, where the majority is Magnesiohornblende, accounting for more than 70%, followed by Tschermakite. A genetic mineralogical analysis was carried out on the genesis type, magmatic source, and crystallization temperature and pressure environment of the amphiboles in the Huanghe River and Changjiang River estuaries, showing that most of the calcic amphiboles in these estuaries originated from metamorphic rocks, followed by magmatic rocks. Amphiboles of magmatic genesis in the Huanghe River and Changjiang River estuaries were largely crust-mantle type. Most of the metamorphic amphiboles originated in a metamorphic environment below moderate temperature and pressure. The amphiboles of the Huanghe River estuary mainly originate from the orogenic belt in the Northern Loess Plateau. The amphiboles of the Changjiang River estuary mainly originate from the middle and upper reaches of the Changjiang River, where the amphiboles mainly form as a result of magmatic and hydrothermal activity, as well as metamorphism. The chemical composition and characteristic values of sedimentary amphiboles in the Huanghe River and Changjiang River estuaries are stable, and can be used as standardized substances for terrestrial sediments.

对从黄河口五个采样点和长江口六个采样点提取的343个和406个沉积闪石单矿物样品进行了电子探针分析。使用这些样品确定了两条河流的闪石单矿物主要元素的剖面。根据23种氧标准品计算了749种安非他命的阳离子系数和相关参数，确定了其晶体结构分子式和相关的特征结晶化学值。结果表明，两个河口的沉积闪石属于钙化角闪石亚组，其中以菱镁矿占多数，占70％以上，其次是Tschermakite。对成因类型，岩浆源，黄河和长江河口的闪石的结晶温度和压力环境，表明这些河口的钙质闪石大部分来自变质岩，其次是岩浆岩。黄河口和长江口岩浆成因的闪石主要为地幔幔类型。大多数变质闪石起源于低于中等温度和压力的变质环境。黄河口的闪石主要来自黄土高原北部造山带。长江口的闪石主要来自长江中上游，这些闪石主要是由于岩浆和热液活动以及变质作用而形成的。
