Analysis reveals sediment composition and foraminiferal chemistry in a coastal region, indicating environmental impacts.

The aim is to analyze the shell chemistry of foraminifera and sediment characteristics along a coastal stretch in Ernakulam.
Collection of thirty sediment samples from Munambam to Kuzhupilly beach
Estimation of calcium carbonate, sand, silt, and clay content
Identification of heavy minerals through sediment analysis
Energy Dispersive Spectroscopy (EDS) for rare trace elements in foraminifera
Ammonia beccarii was the only foraminiferal species identified in the area
Sample MB19 showed significant chemical anomalies in foraminifera and heavy minerals
Higher silt content and dark-colored sediments observed in sample MB19
Rare earth element Thulium (Tm) found in Ammonia beccarii at location MB19
Presence of Bromium (Br) mineral identified in the sediments of MB19.
