Geological Survey & Mineral Resources Board
The Geological Survey and
Mineral Resources Board is a component of the
Ministry of the Oil and Minerals. The
predecessors to the GSMRB formed in the early
1970’s when there were several smaller entities
dealing with various geological and minerals
matters. When Yemen unified in 1990 these
entities amalgamated and after several name
changes was established as the Geological Survey
& Mineral Resources Board by republican decision
number (317) for the year 1999.
Responsibilities of the GSMRB
-
Conducting geological
surveying and the compilation of geological
maps.
-
Carrying out
exploration work and preparation of the
mineralogical maps.

studies and research concerning mineral
resources.

agreements for the exploration and
exploitation of mineral resources
and supervising the activities of companies
engaged in exploration and exploitation.
-
Analysis and
testing of mineral ores and industrial
minerals.

Issuing
licenses for the investors in the field of
mineral resources.
-
Supervision of
the widespread seismic station network.

Geological
& Thematic Maps
As
a result of several studies and geological
research carried out by the Geological Survey
and Mineral Resources Board (GSMRB),
in cooperation with foreign missions, there are
numerous types of maps available over the
Republic of Yemen. Geological,
Topographic, Hydrogeological, Volcanic &
Earthquake Hazard, Synoptic, Magnetic Anomaly,
Radiometric, Potential Exploration Groundwater
Resources and Thematic Maps are available in a
scales varying from 1:50,000 to 1:1,000,000.
Geological Maps at
a 1:100,000 scale
The
GSMRB
considers complete geological mapping of Yemen
at a scale of 1:100,000 to be of utmost
importance to stimulating mineral exploration.
This mapping commenced in 1990 with the
assistance of the BGR and more recently the
project has been taken over by the GSMRB.
To date 22 maps have been completed and a
further 200 are in progress.
Thematic
Maps in a scale of 1:50,000
A
thematic map displays selected kinds of
information relating to one or more specific
themes, such as environment pollution, water
management, soil, land-use, population density,
and so on. These maps show the distribution of a
wide variety of qualitative & quantitative
information which can be used to guide
sustainable development of ground and surface
water, location of waste disposal sites, and
land use planning. The GSMRB has compiled
thematic maps on water pollution, oil station
locations, quarries and crushers.
