Intrusion-related gold mineralization: Inata gold deposit, Bélahourou district, Northern Burkina Faso (West-Africa)
Herman Ilboudo, Sâga Sawadogo, Abraham Seydoux Traoré, Martial Sama, Urbain Wenmenga, Martin Lompo
The Inata cluster of gold deposits is one of ten gold deposits currently in exploitation in Burkina Faso. The aim of
this work was to assess the influence and contribution of the magmatic events in the metallogenic system. Our
approach is based on detailed field observation and petrography of different lithologies encountered in the main
pi(...)

GHASP: an Hα kinematical survey of spiral galaxies - XI. Distribution of luminous and dark matter in spiral and irregular nearby galaxies using WISE photometry
M. Korsaga, C. Carignan, P. Amram, B. Epinat and T.H. Jarrett
We present the mass distribution of a sample of 121 nearby galaxies with high-quality optical velocity fields and available infrared Wide-field Infrared Survey Explorer(WISE) 3.4 μm data. Contrary to previous studies, this sample covers all morphological types and is not biased towards late-type galaxies. These galaxies are part of the Fabry-P(...)

The Belahourou granite pluton (Djibo Greenstone belt. Burkina Faso): Emplacement mechanism and implication for gold mineralization along a shear zone
Sâga Sawadogo, Séta Naba, Hermann Ilboudo, Abraham Seydoux Traoré, Samuel Nakolendoussé, Martin Lompo
The Belahourou granite pluton (BG pluton) is a magmatic body that belongs to the Djibo greenstone belt,
north Burkina Faso. Calc-alkaline in composition and 2132 ± 4 Ma in age (U-Pb zircon), this pluton is
bordered by the curved Belahourou-Souma (BS) sinistral shear-zone, NNW-trending in the northern half
of the pluton and WNW-trending in t(...)

Modeling of the Alteration Wedge in a Crystalline Basement Environment: Case Study of Burkina Faso Central Regions
Kafando Sayoba, Nakolendoussé Samuel, Nikiéma Julien
The alteration wedge is unevenly distributed in the central region of Burkina Faso. Outcrops of crystalline rocks can be seen everywhere on the sheet. Water drilling data made it possible to highlight this inequality. The frequency of the encountered alteration depths associated with the water productivity of the underlying aquifers made it po(...)

Hermann ILBOUDO, Abraham Seydoux TRAORÉ , Sâga SAWADOGO , Bokkum NONGUIERMA , Sienini TOUBANIA
The lithofacies of Gombélédougou area, in southern Burkina Faso are part of the Houndé greenstone stones belt that extends over 225km long and 40km wide.
Despite the narrowness of the study area, investigations based on both field and laboratory highlight a variety of rocks that contribute to fully update the geological data base of previous(...)

Geochemical and Geodynamic Constrain of Tholeiitic Volcanism and Related Intrusions in the Kampti Gold District, Southwest Burkina Faso: Implication for Mineral Exploration
Mathieu Nanema , Urbain Wenmenga & Hermann Ilboudo
The Kampti serie is a volcano-plutonic complex in the south-eastern corner of the Houndé belt, closed to the border with Ivory Coast. The stratigraphy comprises initially: a thick sequence of tholeiitic and pillowed basalt followed by pyroclastic projections derivated from bimodal volcanism; and flowing mostly to the south. The volcanic sequen(...)
