The following points highlight four sampler that are conventionally used for trapping pollen grains. The samplers are: 1. Rotorod Sampler 2. Burkard Personal Volumetric Sampler 3. Burkard Seven Day Volumetric Sampler 4. Andersen Two Stage Sampler. 1. Rotorod Sampler: The rotorod sampler (Fig.10.10) was originally devised by Perkins (1957) and has been somewhat modified by Harrington (1959). The device relies [...]
The deposit that contains pollen grains and spores suitable for identification and analysis include peats, lake sediments, soil and mor humus. Peats: Peats are the early stage of coalification which are formed due to accumulations of organic detritus largely of plant origin. Peats are developed into a stratified sequence due to the successive deposition of plant parts containing pollen and [...]
The parameters that used in the exploration of such hydrocarbons are discussed below: 1. Determination of Ancient Shore Lines 2. Sedimentology 3. Post Depositional Alteration of Palynomorphs 4. Biostratigraphy and Palaeo- Environmental Analysis 5. Palynological Assemblages of Coal Seams. 1. Determination of Ancient Shore Lines: The defining of ancient shore lines bears special significance in oil accumulation. It is generally [...]
