Instruments used for Collection of Core Samples

The following points highlight the four main instruments that are used for collection of core samples. The Instruments are: 1. Hiller Borer 2. Russian Borer 3. Piston Sampler 4. Mackereth Sampler. 1. Hiller Borer (Fig.13.1): In this instrument the filling of sediment is done by turning the apparatus anti-clockwise. Here outer, loose jacket with a projecting lip remains stationary and [...]

Techniques for the Extraction of Pollen Grains

The following points highlight the two laboratory techniques for the extraction of pollen grains. The techniques are: 1. Pollen/Spore Extraction Pro­cedure 2. Absolute Pollen Counts. 1. Pollen/Spore Extraction Pro­cedure: It is not possible to use the entire core systematically for pollen extraction, hence samples are taken at selected depth intervals along the core. The selection of depth intervals is entirely [...]

Quaternary Pollen Records in Different Places of India

In this article we will discuss about the quaternary pollen records in different places of India. It was Huntington (1906) who initiated the pollen analysis in India from the sediments of Pangong Lake in Ladakh. Later, Wodehouse (1935), De Terra & Paterson (1939) worked out palynologically Indian Quaternary sediments. The investigations on pollen analysis to establish the Quaternary vegetation history, [...]
