The One

The Dougbafla gold deposit is located in the West-Central part of Côte d’Ivoire at about 240 km from Abidjan, on the Birimian greenstone belt of Fettèkro (West African craton). The lithologies of this deposit can be divided into three lithotectonic units which correspond to volcanic, sedimentary, and plutonic assemblages metamorphosed in the shale facies. Hydrothermalism, on the one hand, caused a pervasive alteration of the primary paragenesis marked by sericitic, silica, and carbonate alteration. On the other hand, it causes a vein alteration materialized by quartz veins. These hydrothermal alterations induced two types of gold mineralization in the Dougbafla deposit. These are: (i) disseminated gold and sulphide mineralization in the granophyre associated with sericite, silica and dolomite alteration in which no quartz vein has been reported; this type however is controlled by the intrusion of granophyre and (ii) a quartz vein mineralization controlled by deformation.

The article presents a new view on the problems of political stability in West African countries. For the first time was carried out a comparative analysis of the sustainability of the political systems of the two Francophone fastest growing countries in West Africa, Côte d’Ivoire and Senegal. The author analyzes the factors negatively influencing political stability social order, and those that reduce conflict potencial in these States. Internal and external threats to the political systems of Senegal and Сôte d’Ivoire are examined. The response of both countries to internal and external challenges is shown. The study proves that while external threats indanger Senegal’s political stability, such as the penetration of religious extremism, the crisis in Casamance, maritime piracy, drug traffic, for Côte d’Ivoire, on the contrary, main risks are internal: electoral, socio-political crises, the split of elites, arms smuggling, banditry. The study demonstrates that the level of social governance in Senegal is higher than in other West African countries, including Сôte d’Ivoire, due to the dualism of the political system: the coexistence of Western-style political institutions with local faiths (tariqas), as well as policy pursued by President M. Sall. aimed at achieving mutual compromise that ensure the peaceful settlement of conflicts and contradictions. The author concludes that a new approach to the development of a security strategy is required.
