Launching of four new Thematic Maps

The above mentioned four thematic maps are;

• 1:300,000 scale Geochemical Atlas (Vol. Env 1 Sheet 20: Rakwana - Tangalla),

• 1:250,000 scale Four-quadrant Provisional geological map covering the entire country,

• 1:50,000 scale Three Quaternary Geological maps, namely, Kalutara, Balapitiya-Ambalangoda and Matara and

• (1:150,000) scale Mineral Map of the Central Province

of the four maps, the GSMB Geochemical Atlas covers  southern part of the Southern Province  and NW and NE parts of the Sabaragamuwa and Uva Provinces respectively, depicts the distribution of chemical elements of the area, enabling professionals to determine, inter alia, the influence on soil fertility, forestry, water quality and human-animal health. Considering the area it covers, this map, will undoubtedly be a much sought-after document for development plans of Hambantota and its vicinity. The GSMB plans to generate a series of Geochemical Maps at the same scale by continuing this geochemical mapping programme island-wide and compile the National Geochemical Atlas that could contain nearly twenty maps.

This Atlas will be an extremely valuable multi-user data base and consequently a powerful tool for scientists and national-level planners from different sectors such as land-use, urban planning, environmental management, monitoring industrial pollution and mitigating endemic health problems, in mineral exploration and academic studies of the upper continental crust.

The four-quadrant Provisional Geology map provides a synoptic view of the country’s rock types, their associations, geological structure, drainage patterns, etc. and therefore will be an essential map for mega development projects. At its scale of 1:250,000, in addition to its manifold geologic value, it would also be an ideal start-up map to demarcate new electoral boundaries.                                           

The three Quaternary Geological maps namely, Kalutara, Balapitiya-Ambalangoda and Matara, at 1:50,000 scale, contain valuable geological information useful for various disciplines including mineral and ground water exploration, civil and geotechnical engineering, etc.

The Central Province Mineral Resources map could no doubt be used to augment its development portfolio by adding mineral based industries. The GSMB plans to prepare similar maps covering all Provinces.

The Maps Launching Ceremony  was   held at BMICH on 16th October 2017   in line with the Sri Lanka Next  Program organized by the Ministry of Environment and Mahaweli Development  and   his Excellency Maithripala Sirisena, President of the Democratic Socialist Republic of Sri Lanka graced this occasion as its Honoured Chief Guest.
