Abstract

Sediment characteristics and distribution analysis along the Chandipur Coast in Odisha, India was performed using a variety of techniques that include sedimentary characteristics including variation in grain size, shape and character of quartz grain surfaces (determined in light microscope and electron microscope scanning). Samples were taken from various locations representing high-tide areas and low-tide areas for analysis of the grain size, intended to determine physical properties and textural parameters such as mean, sorting, skewness and kurtosis. Grain size distribution research was conducted to characterize sedimentary transportation behaviours. CM diagram defines the rolling, saltation and graded suspension process for sediment deposition at the beach. Linear Discriminant Function (LDF) indicates the superiority of marine environment with lower deposition areas. Scanning Electron Microscope (SEM) was used to examine the quartz grains to determine the origin of the sediments and to establish the physical and chemical processes that occurred during their period of deposition in recent coastal sediments.

摘要

印度奥里萨邦昌迪布尔海岸沿线的沉积物特征和分布分析是使用多种技术进行的，这些技术包括沉积特征，包括石英颗粒表面的粒度、形状和特征的变化（通过光学显微镜和电子显微镜扫描确定）。从代表高潮区和低潮区的不同位置采集样品用于分析粒度，旨在确定物理特性和纹理参数，例如平均值、排序、偏度和峰度。进行了粒度分布研究以表征沉积迁移行为。CM图定义了海滩沉积物沉积的滚动、跃移和分级悬浮过程。线性判别函数（LDF）表明沉积面积较低的海洋环境的优越性。扫描电子显微镜 (SEM) 用于检查石英颗粒以确定沉积物的来源，并确定它们在最近沿海沉积物中沉积期间发生的物理和化学过程。
