The Geological Survey of India (GSI) is a scientific agency of India.It was founded in 1851, as a Government of India organization under the Ministry of Mines, one of the oldest of such organisations in the world and the second oldest survey in India after the Survey of India (founded in 1767), for conducting geological surveys and studies of India, and also as the prime provider of basic ...
The Geological Survey and Mineral Exploration of Iran or in brief GSI is a government agency responsible for conducting geological and mineral surveys throughout the country, collecting the results of activities carried out in this field, establishing coordination, preparing and publishing geological maps of Iran.
A geologic map or geological map is a special-purpose map made to show various geological features. Rock units or geologic strata are shown by color or symbols. Bedding planes and structural features such as faults , folds , are shown with strike and dip or trend and plunge symbols which give three-dimensional orientations features.
National Geological Monuments are geographical areas of national importance and heritage, as notified by the Government of India's Geological Survey of India (GSI), for their maintenance, protection, promotion and enhancement of geotourism. [1] [2] [3]
Digital geologic mapping is the process by which geological features are observed, analyzed, and recorded in the field and displayed in real-time on a computer or personal digital assistant (PDA). The primary function of this emerging technology is to produce spatially referenced geologic maps that can be utilized and updated while conducting ...
The goal of this department is to conduct research in geology, mapping, hydrology, biology, and related sciences; evaluate hazards associated with floods, droughts, hurricanes, subsidence, human activity, and climate change; map the onshore and offshore geologic framework; assess mineral resources and develop techniques for their discovery ...
The Geological Strength Index (GSI) system, proposed in 1994 by Evert Hoek, is used for the estimation of the rock mass strength and the rock mass deformation modulus.. The GSI system concentrates on the description of two factors, rock structure and block surface conditions.
A geological survey is the systematic investigation of the geology beneath a given piece of ground for the purpose of creating a geological map or model.Geological surveying employs techniques from the traditional walk-over survey, studying outcrops and landforms, to intrusive methods, such as hand augering and machine-driven boreholes, to the use of geophysical techniques and remote sensing ...
