Responsibilities

 

Geoelectrical and Seismic branch is one of the main research branches of the Geological Survey of Bangladesh. The branch is responsible for the investigation of solid minerals like coal, limestone, hard rock, metallic mineral etc. in the subsurface of the country. Determination of the stratigraphy and structure of the subsurface are also the part of the above investigation. Collected data are processed by using computer software and analyzed with a view to determine the occurrence of minerals in the subsurface and computer their probable depth and lateral extension. In addition, the branch is also involved with ground water survey and identification of arsenic free aquifers in arsenic polluted areas. Finally, reports are submitted to the authorities with proper recommendation for further follow up work.

 

Achievements

 

The branch has made following achievements:

1)       By using Refraction seismic survey the occurrence and depth of coal bearing Gondwana sediments in Barapukuria and Dighipara areas of Dinajpur district are determined. Configuration and nature of the basins have also been delineated.

2)       In addition, determination of stratigraphy and structure of the subsurface and outline of the basins in different locations of the     northwestern part of the country have been marked.

3)       Investigation of limestone at shallow depth by using Electrical resistivity surveys along Takerghat to Jaflong areas near International Boundary under the district of Sylhet and for hard rock in Madhyapara area of Dinajpur district have been done.

4)       Investigation of ground water at shallow depth using resistivity and Ip surveys have been carried out in Mongla port area of Bagerhat district and the hill tracts district of Rangamati, Bandarban and Khagrachhari.

5)       Moreover, resistivity method has also been to investigate arsenic-free aquifers in the Upazilas of Kachua and Rajoir under the district of Chandpur and Madaripur respectively.

 

As a follow-up of the above investigations, a number of report have been submitted in the Geological Survey of Bangladesh. Some of them already been published in the Geological Survey of Bangladesh record series. Others are selected for publication or will be published in due time. Some reports have been published in the Geological Survey of Bangladesh record series. In addition, some relevant articles have been published in different local and international journals. The name of the reports and articles are as follows:
