This cartographic survey has been done from the samples of cores of polls achieved on longitudinal and transverse profiles as well as by the modelling, appropriated precisely in the concession of the mining of Bakwanga on the massif 12. Of these data of polls, we could achieve a cartographic survey and deduct the structure of this massive kimberlitic under survey. Let’s note that most polls on this massif, met the sand, sandstone, the epiclastic kimberlite, the xenokimberlite, the massive kimberlite and the limestone. In a general manner, to part the limestone, the dolomite, sandstone and the sand, three facies kimberlitics has been put in evidence in this publication and it, according to the percentage in kimberlitics elements, it is about of: - The kimberlite very tender epiclastic (0-25% of kimberlitic elements). - The little strengthened xenokimberlite (25-50% of kimberlitic elements). - The massive kimberlite (beyond 75% of kimberlitic elements).

Abstract
This cartographic survey has been done from the samples of cores of polls achieved on longitudinal and transverse profiles as well as by the modelling, appropriated precisely in the concession of the mining of Bakwanga on the massif 12. Of these data of polls, we could achieve a cartographic survey and deduct the structure of this massive kimberlitic under survey. Let’s note that most polls on this massif, met the sand, sandstone, the epiclastic kimberlite, the xenokimberlite, the massive kimberlite and the limestone. In a general manner, to part the limestone, the dolomite, sandstone and the sand, three facies kimberlitics has been put in evidence in this publication and it, according to the percentage in kimberlitics elements, it is about of: - The kimberlite very tender epiclastic (0-25% of kimberlitic elements). - The little strengthened xenokimberlite (25-50% of kimberlitic elements). - The massive kimberlite (beyond 75% of kimberlitic elements).

Abstract: (french)
Cette étude cartographique a été effectuée à partir des échantillons de carottes de sondages réalisés sur des profils longitudinaux et transversaux ainsi que par la modélisation, prélevée dans la concession de la minière de Bakwanga précisément sur le massif 12. De ces données de sondages, nous avons pu réaliser une étude cartographique et déduire la structure de ce massif kimberlitique sous étude. Notons que la plupart des sondages sur ce massif, ont rencontré le sable, le grès, la kimberlite épiclastique, la xénokimberlite, la kimberlite massive et le calcaire. D’une manière générale, à part le calcaire, la dolomie, le grès et le sable, trois faciès kimberlitiques ont été mis en évidence dans cette publication et cela, en fonction du pourcentage en éléments kimberlitiques, il s’agit de: - La kimberlite épiclastique très tendre (0-25% d’éléments kimberlitiques). - La xénokimberlite peu consolidé (25-50% d’éléments kimberlitiques). - La kimberlite massive (au-delà de 75% d’éléments kimberlitique).
