dc.description.abstract |
A unique carbonate rock developed naturally as a natural barrier presumably
appropriate for advanced marine ecosystems including microbiotas in shorelines. A
great deal of progress has been made in recent years to investigate the chemical
characteristics of beachrocks. Beachrocks found in Krakal-Sadranan Beach can be
categorized into non-beachrocks, unconsolidated beachrocks (similar to carbonate
sands), and well-consolidated beachrocks, which mainly consist of rocks and
minerals. A depletion of Sr concentration in the beachrocks indicates that the
diagenetic processes have progressed from the land to the seashore, most likely
post-deposition of the beachrock and carbonate sand. An increased concentration of
Rare-Earth-Element (£REE), both heavy REE (Tb, Dy, Y, Ho, Er, Tm, Yb and Lu) and
light REE (La, Ce, Pr, Nd, Sm, Eu and Gd) signals that the beachrock deposition
process happened at oxidative environmental conditions. Unmanned aerial vehicle
(UAV) drone mapping, geological analysis, and geophysical surveys were
conducted to detect the underground structure of the beachrocks and to emphasize
the coastal mapping based on targeted beachrock.The mechanism of beachrock
formations obtained in this study would be a novel concept and applicable for the
coastal zone improvements and preservations for further studies.
