Geology and foraminifera occurrence at Chiku 3, Gua Musang, Kelantan

This research entitled Geology and Foraminifera Occurrence at Chiku 3, Gua Musang, Kelantan. The area of mapping study is located at Chiku 3 area. Three objectives was provided which is to update the geological map of study area with scale of 1:25000, to identify the occurrence of foraminifera in study area and to identify its paleo-environment based on foraminifera occurrence. To complete this research, field observation and and sampling method were done during geological mapping activity. While for the specification part, foraminifera been process through crushing, sieving and drying method and then was analyzed through picking and sorting method for the naming of it species. From the geological mapping activity, study area consists of four lithology unit which is pyllite unit, tuff unit, mudstone unit and limestone unit. From the analysis, the occurrence of foraminifera in Chiku 3 was dominantly by benthic foraminifera. Besides, in order to identify its paleo-environment, the paleobathymetry determination is used by using benthic foraminifera as indicators. Based on paleobathymetry determination, the paleoenvironment of the area is from Middle Neritic zone – Outher Neritic zone with the depth around 30-200 m. Hence, this research was significant because the geological information can be used to construct a new geological map and the study of foraminifera occurrence are ideal because its paleo-environment can be identified
