Magnetic iron compounds can also be found in igneous and metamorphic rocks.

Evolution of the Ganga — Brahmaputra Delta: Ancient land surfaces especially from the prehistoric era can be difficult to discern so this technique is useful for evaluating an areas potential for prehistoric surfaces and archaeological evidence.

Geoarchaeologists use this uniqueness in trace element geochemistry to trace ancient patterns of resource-acquisition and trade.


Radiation Measurements 32 1: References Abstract Archaeological studies in the upper and lower part of the Ganga-Bhaghrathi-Hugli delta were taken up to understand the nature of site formation and human adaptation in a dynamic fluvial zone.

Geographical Review of India 69 3: These readings are often used to detect buried soil horizons. For example, researchers can look at the trace element composition of obsidian artifacts in order to "fingerprint" those artifacts.

In the field, the same reaction is used on detector sticks, which are compared to a colour chart.

Journal of Coastal Research 16 2: Phosphate and orthophosphate content with spectrophotometry[ edit ] Phosphate in man-made soils derives from people, their animals, rubbish and bones. Quaternary Research 71 3: Archaeology of Coastal Bengal. They can then study the trace element composition of obsidian outcrops in order to determine the original source of the raw material used to make the artifact.

Evolution of the lower Gangetic Plain landforms and soils in West Bengal.

Identify buried soils in depositional sequences. Implications for science-policy interaction Quaternary International 2: Particle size analysis[ edit ] The particle size distribution of a soil sample may indicate the conditions under which the strata or sediment were deposited. Some workers Eidt especiallythink that the ratios between these pools can give information about past land use, and perhaps even dating.

Origin of the Australians.

Late Quaternary sedimentary environment geoarchaeological dating landform evolution in the Bengal Lowland. Archaeological Survey of India, New Delhi. Holocene and Modern sediment budgets for the Ganges — Brahmaputra river system, evidence for high stand dispersal to floodplain, shelf, and deep-sea depocentres.

Loss on ignition testing[ edit ] Loss on ignition testing for soil organic content. Artibus Asiae l Particle sizes are generally separated by means of dry or wet sieving coarse samples such as tillgravel and sandssometimes coarser silts or by measuring the changes of the density of a dispersed solution in sodiumpyrophosphate, for example of the sample finer silts, clays.

We suggest that high resolution chronology using Optically Stimulated Luminescence OSL and radiocarbon dating can be quite effective in the study of archaeology and human environment relationship in the Ganga-Brahmaputra Delta GBD.

If more than one tin is needed they are arranged offset and overlapping to one side so the complete profile can be rebuilt offsite in laboratory conditions. Identifying hearth areas and the presence of burning residues in deposits.
