The current study aimed to describe textural characteristics, heavy mineral composition, and grain microtextures of the sediment from three micro-environments (foreshore, berm, and dune). A total of forty-one (41) representative surficial sediment samples have been collected from fifteen (15) locations along the beach area between the Sarada and Gosthani rivers on the east coast of India, where the length of the stretch is more than 100 km. The study reveals that most of the coastal sediment is medium to fine sand with relatively high ratios of coarse sand at Yarada beach, and the nature of the sediment is moderately to well sorted. These characteristics indicate a high energy environment. The heavy mineral analysis of the sediment in the current study was done for coarse (+60#) and fine (+230#) size fractions. Studying the weight percentage (WT%) reveals that a high percentage of heavy minerals is associated with fine fractions. Ilmenite, sillimanite, garnet, zircon, and rutile are the major heavy minerals identified in the current investigation. The concentrations of these heavy minerals show great variations from south to north of the study area. From an economic point of view, a considerable amount of heavy minerals (average 48.41%) are present on both sides (north and south) of the Gosthani River mouth. In the Sarada Estuary, the concentration of the economic heavy minerals was found under the minimum economic range. The grain microtextures of the major heavy minerals from the different locations along the study area demonstrate the variation in grain microtextures, which is controlled by the chemical and mechanical processes. These microtextures reflect moderate to high wave energy on the beach area, in addition to high mechanical impact on the grains from the estuary point.

当前的研究旨在描述来自三个微环境（前陆，河床和沙丘）的沉积物的质地特征，重矿物成分和颗粒微纹理。从印度东海岸的萨拉达河和哥萨尼河之间的海滩地区的十五（15）个地点收集了总共四十一（41）个代表性地表沉积物样本，这些河段的长度超过100公里。研究表明，大多数海岸沉积物是中度至细砂，而雅拉达海滩的粗砂比例相对较高，沉积物的性质适中至分类良好。这些特征表明高能环境。在当前研究中，对沉积物的重矿物分析是针对粗颗粒（+ 60＃）和细颗粒（+ 230＃）进行的。研究重量百分比（WT％）表明，高百分比的重矿物与细颗粒有关。钛铁矿，硅线石，石榴石，锆石和金红石是当前调查中确定的主要重矿物。这些重矿物质的浓度从研究区域的南到北显示出很大的差异。从经济角度看，哥斯达尼河口的两侧（南北）都存在大量的重矿物（平均48.41％）。在萨拉达河口，发现经济重矿物的浓度低于最小经济范围。研究区域不同位置的主要重矿物的晶粒组织表明了晶粒组织的变化，这是由化学和机械过程控制的。
