中文摘要：

黄土是陆地上分布较广、沉积连续的第网纪沉积物，在古气候和全球变化研究中发挥了重大的作用。本文对印度德干高原Panchgini地区黄土进行了地球化学和地球物理学研究，测试了常量元素、稀土元素（REE）、粒度以及系统的环境磁学等参数。实验结果表明：德干高原Panchgini地区黄土与典型风积黄土的粒度组成相似，表明它们具有相似的成因；此外，常量元素含量和稀土元素分配模式都与中国典型黄土相似，上述证据小仪明确了该地区黄土的存在，也表明它们拥有相似的物质来源模式和沉积过程；系统的环境磁学测量表明Panchgini地区黄土中主要的强磁性矿物为磁铁矿，弱磁性矿物为针铁矿和赤铁矿，同时存在一部分顺磁性物质，磁性矿物粒径整体较粗，粒级主要集中在假单畴（PSD）和多畴（MD）之间。

英文摘要：

The widespread loess deposition has been recognized for its excellent geological record regarding paleoclimate and paleomagnetic investigation. The discovery of loess sections have been reported at the alpine steppe area of the Himalayan Mountain chain in India, however no loess deposit has been reported in the area of the Deccan Plateau, in the central south of India. The Deccan Plateau is characterized by thick （ over a thousand meters） basalt lava and about 25m of Fe-rich laterite on the top. The Panchgini loess section （17°55.298′N, 73°48.255′E; altitude 1329m） is located in the Panchgini Tableland, in the northwest of the Deccan Plateau. This loess deposit is found on the top of Fe-bearing laterite. The thickness of the loess section is 60cm. Six samples （Y1- Y6） were collected at 10cm intervals from the land surface down to the top of laterite. Several regular parameters for loess study were measured including particle size, Rare Earth Elements （REE） , major elements and environmental magnetism. Detailed magnetic measurement has been made, such as low and high-frequency magnetic susceptibility, anhysteretic remanent magnetization （ARM） , isothermal remanent magnetization （IRM） , and saturation isothermal remanent magnetization （SIRM）. In addition, magnetic hysteresis loops and thermomagnetic curves （Magnetization with temperature M-T and magnetic susceptibility with temperature K-T） has been measured in order to detect the different kinds of magnetic minerals. The results show great similarity with Chinese loess, for example, grain size frequency distribution curves, accumulation curves and rare- earth elemental distribution patterns. A high degree of major elemental similarity between Indian loess and typical aeolian Chinese loess suggests that both originate from a similar source, or may share a similar formation process involving the thorough mixture of dust particles. The magnetic results show that magnetite is a predominant magnetic mineral in the loess, also indi
