A Review of Tertiary Palynomorph Assemblage in Cuu Long Basin: Case Study of Palynomorphs in Miocene Oligocene Sediments

Nguyen Hoai Chung, Chu Duc Quang, Nguyen Thi Tham

Abstract


Tertiary deposits in Cuu Long Basin are very important because they contain fossil fuels such as oil and gas. More than 50% of oil and gas has been produced in Vietnam from Cuu Long Basin. Palynology is used as a valuable tool to support for depositional and age interpretation as well as well correlation. In this study, a Palynological study has been carried out on ditch cutting samples from a well which was drilled in Cuu Long Basin where situated in the southern Vietnam. Palynological result has revealed the palynomorph assemblages were dominated by typical tertiary palynomorphs such as Stenochlaena palustris, Acrostichum aureum, Polypodiisporites perverrucatus, Polypodiaceaesporites undiff, Osmundacidites, Crassoretitriletes vanraadshoveni, Magnastriatites howardii etc., and others fresh water to brackish algal, i.e. Pediastrum, Bosedinia and Botryococcus groups. The age of the rock succession is probably Late Miocene to Early Oligocene based on the presence of certain stratigraphically significant and age restricted taxa such as Florschuetzia trilobata, Florschuetzia meridionalis, Stenochlaenidites papuanus (Stenochlaenanidites laurifolia), Jussiena spp. Verutricolporites pachydermus, Gothanipollis basensis. Cicatricosisporites dorogensis, Lycopodiumsporites neogenicus, Meyeripolis nahankotensis.

The purpose of this paper aims to introduce the VPI Palynological zonation which is using to clarify the palynological characteristics in the southern shelf of Vietnam.
