Microscale Observations by Digital Imaging for Physical Analysis of a Lake Deposition Sample : an Experimental Study

Abstract

Micrographic studies are considered as one of the important tools for analysis of physical characteristics of sediment depositions. Recent development of digital technology plays very important role for analysis of physico-cheminal and mineralogical compositions of the sediment depositions. In this study the present author attempted to analysis some physical characteristics of late Holocene lake deposition by digital imaging and image processing. For that purpose Rudrasagar lake of Tripura was selected for field work and sample collection. In the sedimentology laboratory a section was prepared from the collected sample for micro-photography under reflected light. Image analysis at micro level was done by multi-processing techniques with several sophisticated image processing software.
