Plant impact on the biogeochemical cycle of silicon and related weathering processes
- A. Alexandre, J. Meunier, F. Colin, J. Koud
- Geology
- 1 February 1997
Abstract The contribution of plants to the biogeochemical cycle of Si and related weathering processes was studied in an equatorial rainforest ecosystem (Congo) where the biologic turnover of Si is… Expand
In situ produced 10Be measurements at great depths: implications for production rates by fast muons
- R. Braucher, E. Brown, D. Bourlès, F. Colin
- Geology
- 30 June 2003
In situ cosmogenic 10Be values have been used to investigate a Brazilian quartz vein from the surface to a depth of 15 m. At depths greater than 1000 g/cm2, deep enough for neutron-induced reactions… Expand
Mineralogical control of organic carbon dynamics in a volcanic ash soil on La Réunion
- I. Basile-Doelsch, R. Amundson, +6 authors J. Meunier
- Geology
- 1 December 2005
In soil carbon dynamics, the role of physicochemical interactions between organic matter and minerals is not well understood nor quantified. This paper examines the interactions between soil organic… Expand
Long-term tropical morphogenesis of New Caledonia (Southwest Pacific): Importance of positive epeirogeny and climate change
- Violaine Chevillotte, D. Chardon, A. Beauvais, P. Maurizot, F. Colin
- Geology
- 29 November 2006
Extensive mapping of relict lateritic landsurfaces over the 1600 m of relief of mainland New Caledonia is used to evaluate long-term morphogenesis of the island since its emergence in the Oligocene.… Expand
Evidence for muon‐induced production of 10Be in near‐surface rocks from the Congo
- E. Brown, D. Bourlès, F. Colin, G. Raisbeck, F. Yiou, Sophie Desgarceaux
- Geology
- 15 March 1995
Distributions of 10Be in vein quartz from a lateritic weathering profile from the Congo provide evidence for significant in situ production of 10Be by reactions other than neutron-induced spallation.… Expand
Computing a null divergence velocity field using smoothed particle hydrodynamics

The development of iron crust lateritic systems in Burkina Faso, West Africa examined with in-situ-produced cosmogenic nuclides
- E. T. Brown, D. Bourlès, F. Colin, Z. Sanfo, G. Raisbeck, F. Yiou
- Geology
- 1 June 1994
We have investigated the development of iron crust laterites on the stable West African Craton in northern Burkina Faso using cosmogenic radionuclides produced in situ in quartz veins and pebbles.… Expand
Generalized Fountain Theorem and applications to strongly indefinite semilinear problems
- C. J. Batkam, F. Colin
- Mathematics
- 29 January 2013
Abstract By using the degree theory and the τ -topology of Kryszewski and Szulkin, we establish a version of the Fountain Theorem for strongly indefinite functionals. The abstract result will be… Expand
Occurrence of mycorrhizal symbioses in the metal-rich lateritic soils of the Koniambo Massif, New Caledonia
- N. Perrier, H. Amir, F. Colin
- Biology, Medicine
- Mycorrhiza
- 21 June 2006
The occurrence of arbuscular mycorrhiza (AM) was surveyed in ten endemic plant species of the Koniambo Massif (New Caledonia) and associated metal-enriched ultramafic soils along a topographic… Expand
Canopy structure and light interception in Quercus petraea seedlings in relation to light regime and plant density.
- L. Farque, H. Sinoquet, F. Colin
- Biology, Medicine
- Tree physiology
- 1 November 2001
Foliage structure was measured on 1- and 2-year-old Quercus petraea (Matt.) Liebl. seedlings grown in 100 or 18% sunlight at a planting density of 2.8 or 25 plants per m(2). A three-dimensional… Expand
