Abstract: | Water chemistry, sediment texture, clay mineralogy and foraminiferal contents from the bottom of Meda creek were studied to
assess the geo-environmental status of the creek. Water quality data for three seasons suggests domination of marine environment
as pH remained above 8 and salinity above 35‰ throughout. Clay dominate the bottom sediments, except near mouth. Montmorillonite,
illite and kaolinite are the major clay minerals in the sediments. In absence of any source rock in the catchment of the Meda
creek, the presence of illite and kaolinite indicates their transportation and depositions from near coastal waters during
high tides. Ammonia sp. is the most dominating foraminifera. Reworked forms as well as angular asymmetric forms of foraminifera were dominant
in clay rich areas of the creek. |
