Geological Survey and Mineral Resources Authority
The Geological Survey and Mineral Resources Authority is one of the main units of the Ministry of Oil and Minerals, established by Presidential Decree No. (317) of 1999. It is concerned with the information related to the earth sciences in Yemen.
The establishment of the Authority dates back to the early seventies of the last century. Then, the Geological Survey and Mineral Resources Authority in 1999.
The main objectives
Conducting geological surveys and preparing geological and purpose maps.
Conducting mineral exploration and research activities, and conducting research related to Earth sciences.
Granting exploration, exploration and mineral exploitation licenses.
Monitoring the activities of mining companies.
Supervising the seismic and volcano monitoring center.
Preparation and implementation of plans and programs to promote open areas.
Providing technical information and services related to earth sciences to state institutions and investors.

Introduction to the geology of Yemen
Interest in the geology of Yemen began a long time ago, the first study of the geology of Yemen appeared in (1912) prepared by Botez (Botez).
The first serious and intensive geological study was conducted in the northern governorates by Geokins for the period (1960-1966), and the first integrated geological column for the layers of rocks in these provinces from the pre-Cambrian era until the quadruple.
The first preliminary geological map was prepared during the period (1975-1978) for the northern governorates on a scale (1: 50000) by Grolier Waverstreet.
Publication of the first geological book on the geology of the northern governorates of the Republic of Yemen by El-Anbaawy (El-Anbaawy, 1985a).
Detailed stratigraphic geologic studies were carried out successively by individual researchers or by the Geological Survey and Mineral Resources Authority until the World Stratigraphic Guide was published in 1998 as it is the most recent stratified reference currently.
The Republic of Yemen covers rocks ranging from the pre-Cambrian period to the modern era. About 2.9 billion years.
Yemen’s geology is also related to the regional structure of the Arab board in its different stages of development and is characterized by regional characteristics during successive geological eras since the Lower Proterozoic Era to the present.
Accordingly, the geology of Yemen can be briefly divided into:
1- Basement rocks. (Pre-Cambrian). Bottom protozoic
Sediment cover.
– Rocks under the Paleozoic Cambrian.
– Mizuzui rocks
– Kinosoy rocks.
3 – volcanic rocks
– Yemen Revelations (YTS)
– Yemen Volcanoes (YVS)
4 – quadrilateral deposits
– Old beach sediments
– River, religious and marine sediments.
Metallic Minerals in Yemen
Exploration studies carried out by the Geological Survey as well as local, Arab and foreign mining companies showed the discovery of many mineralized sites such as mineralization of gold, lead, zinc, copper, silver, nickel, iron and titanium. These studies showed that the geological environment and other factors in Yemen are somewhat similar to the ideal models recorded regionally and globally. Based on the geological studies carried out, investment opportunities in Yemen’s metallic minerals have been identified in several areas such as gold, copper, nickel, platinum, and zinc. – Lead, iron – titanium, rare earth metals, tungsten, tin, radioactive elements.
