Chemical and mineralogical signatures of mudstones from the Agnone Flysch turbidite successions (late Tortonian to early Messinian) deposited in the Lagonegro-Molise foredeep basin reveal new insight for the sedimentary evolution of the southern Apennines during late Miocene. Geochemical and mineralogical signatures of the Verrino and Poggio Villanelle members of the Agnone Flysch mark a complex sedimentation history testifying to a multi-source area probably due to structural changes and depositional basin physiography. The studied mudstones show chemical variations in term of Ca vs. Si and Al. Mineralogical analyses confirm a decrease of carbonate minerals and an increase of silicate phases passing from Verrino Member to Poggio Villanelle Member samples. Compositional data of the mudstone samples of both members mainly record a derivation from felsic rocks due to the Calabrian terranes unroofing. Poggio Villanelle Member samples further show an enrichment in Cr, Ni, Fe e Mg in accordance with higher chlorite content suggesting a mafic supply probably related to an ophiolitic source successively exposed. Thus, those trends based on chemical and mineralogical data suggest a change in relative abundance of a detritus characterized by different compositions through time and space. Whole rock geochemistry of the studied mudstones indicate that they are from the first-cycle sediments.

Palaeoweathering processes in source areas were moderate as shown by CIA (Chemical Index of Alteration) and CIA’ (modified Chemical Index of Alteration) values of the mudstones of both members (Verrino and Poggio Villanelle members). The trends observed in the paleoweathering diagrams suggest source areas characterized by moderate weathering in non-steady-state conditions which have changed toward the upper portion of the sedimentary succession. Those changes are mainly related to the geodynamic conditions of the source areas where active tectonism allows erosion of all zones within weathering profiles developed on source rocks.

The paleocurrent data and the compositional analysis of the mudstones and sandstones indicate a provenance (supply) from the western, north-western, and south-western sectors of the basin where carbonate platforms and magmatic, metamorphic and sedimentary rocks cropped out.

沉积在 Lagonegro-Molise 前深盆地的 Agnone Flysch 浊积岩系列（托托阶晚期至墨西拿阶早期）泥岩的化学和矿物学特征揭示了中新世晚期亚平宁山脉南部沉积演化的新见解。Agnone Flysch 的 Verrino 和 Poggio Villanelle 成员的地球化学和矿物学特征标志着一个复杂的沉积历史，证明可能是由于结构变化和沉积盆地地貌造成的多源区。所研究的泥岩在 Ca 与 Si 和 Al 方面表现出化学变化。矿物学分析证实了从 Verrino 段到 Poggio Villanelle 段样品的碳酸盐矿物减少和硅酸盐相增加。两个成员的泥岩样品的成分数据主要记录了由于卡拉布里亚地体开顶而衍生自长英质岩。Poggio Villanelle 成员样品进一步显示了 Cr、Ni、Fe e Mg 的富集，这与较高的绿泥石含量一致，表明可能与蛇绿岩源连续暴露有关的镁铁质供应。因此，这些基于化学和矿物学数据的趋势表明，随着时间和空间的不同，以不同成分为特征的碎屑的相对丰度发生了变化。所研究泥岩的全岩地球化学表明它们来自第一旋回沉积物。Fe e Mg 与较高的绿泥石含量一致，表明镁铁质供应可能与连续暴露的蛇绿岩来源有关。因此，这些基于化学和矿物学数据的趋势表明，随着时间和空间的不同，以不同成分为特征的碎屑的相对丰度发生了变化。所研究泥岩的全岩地球化学表明它们来自第一旋回沉积物。Fe e Mg 与较高的绿泥石含量一致，表明镁铁质供应可能与连续暴露的蛇绿岩来源有关。因此，这些基于化学和矿物学数据的趋势表明，随着时间和空间的不同，以不同成分为特征的碎屑的相对丰度发生了变化。所研究泥岩的全岩地球化学表明它们来自第一旋回沉积物。

如两个成员（Verrino 和 Poggio Villanelle 成员）泥岩的 CIA（化学变化指数）和 CIA'（修改后的化学变化指数）值所示，源区的古风化过程是中等的。在古风化图中观察到的趋势表明，源区在非稳态条件下以中等风化为特征，已向沉积序列的上部变化。这些变化主要与源区的地球动力学条件有关，活动构造使烃源岩上发育的风化剖面内的所有带都受到侵蚀。

古水流资料和泥岩和砂岩的成分分析表明，该盆地西部、西北部和西南部有碳酸盐台地和岩浆岩、变质岩和沉积岩出露的物源（供应）。
