Pollen and Spore Atlas For The Cenozoic of The Malay Basin, Malaysia

By: Robert J. Morley and Jaizan Hardi Mohamed Jais

Preamble

This Pollen and Spore Atlas for the Cenozoic of Malaysia presents for the first time detailed descriptions with full nomenclatural details of 186 pollen, spore and algal form-taxa that are important in the evaluation of the palynostratigraphy and environment interpretation in the Oligocene to Pliocene succession of the Malay Basin. The Atlas will also be useful in the neighbouring areas of Sarawak and Sabah, and in Indonesia, Brunei, Vietnam, Thailand and Myanmar, where the Cenozoic sediments yield a similar pollen flora. The Atlas also discusses palynological sampling methods, processing, and interpretation of palynological data and presents a palynological zonation for the region building on earlier studies from the Malay Basin. It also discusses the mode of dispersal and deposition of pollen and spores into sediments and outlines the main vegetation types from which the pollen and spores are likely to have been derived.

The Atlas will be of use for stratigraphic palynologists working across the broad region, but also for workers on Quaternary palynology and archaeology, for whom a suggested name is given for each taxon in addition to the form-taxon name.

The 186 form-taxa represent all the main groups of pollen and spores, and are distributed as follows: alete, 1; monolete, 18; trilete, 21; polyplicate, 1; monosaccate, 2; bisaccate, 6; inaperturate, 3; monocolpate, 7; dicolpate, 3; tricolpate, 16; stephanocolpate, 1; monoporate, 3; diporate, 1; triporate, 32; stephanoporate, 7; periporate, 6; tricolporate, 26; stephanoporate and periporate, 8; heterocolpate, 2; syncolpate, 8; tetrads, 5; polyads, 1 and algae, 8.

The Atlas describes 7 new genera, 55 new form-species, 4 new forms and 10 new combinations as follows:
