Implication

Analysis uncovers sediment characteristics in an estuarine environment, indicating depositional processes.

Key Points

  • The research aims to analyze sediment characteristics and depositional environments at Marakkanam estuary.
  • Collection of sediment core samples using PVC pipes
  • Subsampling performed at regular intervals for analyses
  • Statistical calculations of grain size, standard deviation, skewness, and kurtosis
  • Heavy mineral analysis to determine mineralogy and provenance
  • Predominance of fine sand with well to moderately well-sorted sediment texture
  • Mean sediment sizes indicate fine sand prevalence (ranging from 2.24 to 2.62)
  • Moderately well to well sorted sediments suggested by standard deviation values (0.454 to 0.851)
  • Bimodal frequency distribution curves indicate variable depositional conditions
  • High concentrations of zircon, tourmaline, and rutile identified in heavy mineral analysis
