“…K, N org , C org , Ti, Al and Si) are characteristic of the soils developed upon the volcanosedimentary setting that can be found around the ultramafic Koniambo outcrop ( Fig. 1; Houles et al, 2018;Vincent et al, 2018). The second cluster is thus considered to represent the volcano-sedimentary source to the studied sediments and the results of the HCPC analysis show that the reference station (ST16) is the most exposed to this source (Fig.…”

“…The Chasseloup Bay is located downstream of a volcano-sedimentary setting mainly composed of Acrisols, Cambisols Vertisols and Fluvisols (Fritsch, 2012) that are characterized by medium to high Si, Al, Mg and K concentrations (i.e. up to 40-45 wt%, 7-8 wt%, 4-4.5 wt%, 0.4-0.5 wt%, respectively; Vincent et al, 2018). The Kataviti Bay is located at an intermediate position, downstream of both types of ultramafic and volcano-sedimentary settings (Fig.…”

Pyrite contribution to Ni and Fe speciation is low and restricted to the sediments close to the shore Clay minerals are the major host for Fe and Ni across the shore-to-reef gradient Fe-rich smectite, glauconite, chrysotile and greenalite/berthierine are the major Fe and Ni-bearing clay minerals identified Greenalite/berthierine is the most Ni-rich clay mineral identified and it is considered to have formed in-situ upon early diagenesis Green clay authigenesis might represent a major process for trace metals cycling in shallow lagoon sedimentary settings *Highlights (for review : 3 to 5 bullet points (maximum 85 characters including spaces per bullet point) Lagoon sediments, trace metals, speciation, green clays, TEM, XAS.

“…Cambisols and Vertisols; Fig. 1; do not show significant differences between Cr and Mn concentrations(i.e.340-1500mgŊkg − 1 forCrand820-1000mgŊkg − 1 for Mn; Vincent et al, 2018). The contribution of these soils to trace metals inputs towards the sediments in the Vavouto Bay can thus not explain the higher Cr concentrations in the sediments close to the shore, which are thus mainly attributed to the continental inputs related to the Fer-ralsols at the top of the Koniambo regolith.…”

“…Biological nitrogen-fixation by Acacia species has been previously reported to reach optimal rates on extremely contrasting soils (Vincent et al, 2018). Bakhoum et al (2016) reported beneficial effects of M. plurifarium ORS3588 inoculation on S. senegal growth that could be attributed to the rhizobial inoculant that was used and its highest performance in comparison to indigenous microorganisms.…”

Senegalia senegal (L.) Britton (Fabaceae) is a widespread, multipurpose tree capable of colonizing disturbed Sub-Saharan mining sites given its adaptations to arid lands. The purpose of this study was to determine the potential of the association of microbial and/or manure amendments with S. senegal seedlings for the effective rehabilitation of the environment post mining. A multi-year factorial experiment involving this species was conducted in a nursery and on waste rock dumps (Essakane gold mine, NE Burkina Faso). Inoculation with arbuscular mycorrhizal (AM) fungi (native isolate Rhizophagus aggregatus DAOM2277128; commercial isolate Rhizophagus irregularis DAOM197198) and Mesorhizobium plurifarium strain ORS3588 was conducted on S. senegal seedlings. These were planted in black polythene bags filled with three substrate types: 100% sandy soil (substrate A); 75% sandy soil, 25% manure (substrate B); and 50% sandy soil, 50% manure (substrate C). Seedlings were then out-planted on waste rock to determine whether microbial inoculation improves their growth and survival rates. Under nursery conditions, manure-enriched substrates harboured less nodulation and AM colonization, but substantially increased plant height, and dry mass compared to un-amended substrate. Inoculation on manure-enrich substrates did not consistently increase root AM colonization and plant growth parameters among treatments. Plants that were inoculated with R. aggregatus alone or with R. irregularis or Mesorhizobium plurifarium ORS3588 showed the greatest increase in growth variables. On un-amended substrates, inoculation with R. aggregatus in combination with M. plurifarium or R. irregularis significantly enhanced root colonization rates, without altering plant growth parameters. Yet, inoculation with R. irregularis or M. plurifarium alone did not elicit increases in these parameters, although nodulation was greatly improved by the latter treatment. In field conditions, plant growth and survival were reduced under high rate manure amendments, likely due to less AM colonization and root nodulation that was observed for these treatments in nursery before out-planting. Strongly colonized plants on the un-amended substrate and moderately amended substrate showed greater survival after out-planting. Our results support the general conclusion that microbial inoculation and manure-enriched substrates are a viable option for mining site rehabilitation using S. senegal. They also suggest that manure amendments in forest nurseries should be cautiously applied given that high rates may impede establishment of plant symbioses, thereby affecting their performance on waste rock dumps following out-planting.
