Chavara and Manavalakurichi are the two important areas with heavy mineral deposits in India. Surface samples were collected from five locations, each from Chavara and Manavalakurichi, and were analyzed for their textural parameters and mineralogy. Sediments from both regions are characteristically fine and medium sand. Chavara (CH) sands are moderately well sorted, whereas Manavalakurichi (MK) sands are moderately sorted to moderately well sorted sediments. Linear discriminate functions (LDF) calculated using the textural parameters show deposition environments of aeolian and shallow marine. Ilmenite predominantly exists along with other heavy minerals such as zircon, sillimanite, rutile, monazite, leucoxene, and garnet. The heavy minerals show an increasing trend towards, but its grain size becomes finer and well sorted. The berm and upper foreshore regions shows high concentration of heavy minerals.

印度南部查瓦拉和马那瓦拉库里奇海滩沉积物的质地和矿物学-对比分析

Chavara和Manavalakurichi是印度两个拥有大量矿藏的重要地区。从Chavara和Manavalakurichi的五个地点收集了地表样品，并对其结构参数和矿物学进行了分析。来自两个地区的沉积物都是典型的细砂和中砂。Chavara（CH）沙粒的分类适中，而Manavalakurichi（MK）沙粒的分类适中，沉淀物也属于中等。使用纹理参数计算的线性判别函数（LDF）显示了风沙和浅海沉积环境。钛铁矿主要与其他重矿物一起存在，例如锆石，硅线石，金红石，独居石，白二烯和石榴石。重矿物显示出增加的趋势，但是其晶粒尺寸变得更细且分类更好。
