对爱奥尼亚海ODP 964站的粘土矿物学进行了研究，以重建地中海中部碎屑沉积物输入的变化，并重建过去1500 kyr的相应气候过程。ODP站点964的粘土矿物学表明，沉积物来源从以坡缕石-伊利石-高岭石粘土矿物组合为特征的撒哈拉沙漠向以伊利石-蒙皂石粘土组合为特征的亚平宁半岛（约70万年）发生了重大转变。在~ 700 kyr之前，低蒙皂石含量（10-20%）和高岭石、伊利石和坡缕石变化的强岁差周期表明，地中海中部的陆源沉积物主要来自撒哈拉尘，并受到非洲季风的强烈影响，来自亚平宁半岛的沉积物贡献较小。伊利石/高岭石的比例在北方夏季日照的最大值的增加表明，非洲季风ITCZ系统的北向位移的结果，从撒哈拉南部的灰尘输入减少。在1050和500 kyr之间，蒙脱石含量逐渐增加，这可能与欧洲南部的环境（植被）和/或水文变化有关，这些变化与MPT的发生有关，部分与亚平宁半岛的构造隆起有关。一个显着的增加，在陆源流量观察到约350 kyr，coeval与一个主要阶段的隆起在卡拉布里亚弧。
Clay mineralogy of ODP Site 964 in the Ionian Sea was investigated in order to reconstruct variations in detrital sediment input to the central Mediterranean Sea and to reconstruct the corresponding climatic processes over the last 1500 kyr. The clay mineralogy of ODP Site 964 indicates a major shift in sedimentary sources from the Saharan Desert, which is characterized by a clay mineral assemblage of palygorskite–illite–kaolinite, to the Apennine Peninsula, characterized by an illite–smectite clay assemblage, at ~ 700 kyr. Prior to ~ 700 kyr, the low smectite content (10–20%) and the strong precessional cycles in the variations of kaolinite, illite and palygorskite indicate that terrigenous sediment to the central Mediterranean Sea mainly originated from Saharan dust and was strongly affected by the African monsoon, with a minor contribution of sediment deriving from the Apennine Peninsula. An increase in the illite/kaolinite ratio in the maxima of boreal summer insolation indicates a decreased dust input from the southern Sahara as a result of the northward displacement of the African Monsoon-ITCZ system. A gradual increase in smectite content has been identified between 1050 and 500 kyr, probably associated with environmental (vegetation) and/or hydrological changes in southern Europe linked to the occurrence of the MPT, and partly to tectonic uplift in the Apennine Peninsula. A marked increase in terrigenous flux is observed at around 350 kyr, coeval with a major phase of uplift in the Calabrian Arc.
