Abstract
The Rosebel gold district belongs to the Paleoproterozoic Trans-Amazonian belt associated with sub-meridian crustal shortening. Here, we present new structural observations (cleavage, stretching lineations, veins, fault slip data, aeromagnetic map). The regional cleavage is steeply dipping and bears a steeply plunging stretching lineation. Finite strains are of flattening type. Fault slip data reveal a complex deformation history. The overall strain pattern in the area reflects vertical motions, a feature consistent with pop-down tectonics involving vertical stretch and burial of supracrustal deposits during horizontal shortening of a hot and weak continental lithosphere.

Summary
The Rosebel gold district belongs to the Paleoproterozoic Trans-Amazonian belt (Fig. 1). Related to a limited area, these data are important because the district is the only one currently exploited throughout the Trans-Amazonian belt rich in gold resources This feature, the large amount of unpublished data collected in the Rosebel mining district, and the large-scale structural correlations with western Africa and its important mining potential, are the bases of the present paper.
