Sea beaches are always a good source of heavy minerals around the world. Cox’s Bazar has 120 km of unbroken sandy sea beach. The study includes the sea beaches of 5 upazilas (Moheshkhali, Kolatoli, Ramu, Ukhia, Teknaf) in Cox’s bazaar district for studying the concentration, identification and investigation of heavy mineral deposits along the sandy beaches. This study has concentrated on the physical properties, identification, and abundance of the heavy minerals fraction in sediments collected from the study area. Satellite imagery Landsat-8 OLI was used for remote sensing verifications. The image processing and crucial analysis carried out using Environment for Visualizing Images (ENVI), Arc GIS and Erdas Imagine software. Coastal areas adjacent to Teknaf upazila has a very significant amount of heavy mineral reserves, almost 16%. The study has identified around nineteen variety of heavy minerals from the collected samples in the study area. Ilmenite, Kyanite, Garnet, Rutile, Zircon, Magnetite, Augite, Hornblende, Enstatite, Epidote, Andalusite, Hypersthene, Diopside and Cassiterite have been found the most abundant in the entire study area. The Coastline of Bangladesh was surveyed completely to map the heavy minerals which are potential resources for our national economy.
在世界各地,海滩一直是重矿物的良好来源。考克斯巴扎尔有120公里的完整沙滩。该研究包括考克斯巴扎地区5个upazilas (Moheshkhali、Kolatoli、Ramu、Ukhia、Teknaf)的海滩,以研究沿沙滩的重矿床的浓度、鉴定和调查。本文主要对研究区沉积物中重矿物组分的物理性质、鉴定和丰度进行了研究。利用Landsat-8 OLI卫星图像进行遥感核查。使用环境可视化图像(ENVI), Arc GIS和Erdas Imagine软件进行图像处理和关键分析。毗邻Teknaf upazila的沿海地区拥有非常可观的重矿储量,几乎占16%。该研究从研究区域收集的样本中鉴定出了大约19种重矿物。其中钛铁矿、蓝晶石、石榴石、金红石、锆石、磁铁矿、奥辉石、角闪石、长辉石、绿帘石、红柱石、超辉石、透辉石、锡石最为丰富。对孟加拉国的海岸线进行了全面调查,以绘制我国国民经济潜在资源的重矿物地图。
