Chlorine and bromine abundance in MORB: the contrasting behaviour of the Mid-Atlantic Ridge and East Pacific Rise and implications for chlorine geodynamic cycle
- A. Jambon, B. Déruelle, G. Dreibus, F. Pineau
- Geology
- 5 December 1995
We have analyzed MORB glasses from the Mid-Atlantic Ridge (64°N-20°S) and the East Pacific Rise (7–21°N) for chlorine with an electron microprobe and chlorine and bromine by NAA.… Expand
The Cameroon Hot Line (CHL): A unique example of active alkaline intraplate structure in both oceanic and continental lithospheres
- B. Déruelle, I. Ngounouno, D. Demaiffe
- Geology
- 1 August 2007
The Cameroon Hot Line (CHL) is an active N30°E tectono-magmatic alignment, extending from Pagalu Island to Lake Chad. Its oceanic sector is comprised of six major volcanoes, and the continental… Expand
A new tectonic model for the Cameroon Line, Central Africa
- C. Moreau, J.-M Regnoult, B. Déruelle, B. Robineau
- Geology
- 1 October 1987
Abstract The Cameroon Line, a major geological feature in Central Africa, has been considered successively as a series of horsts and grabens, a continental rift and a mega-shear zone. It is marked… Expand
The Cameroon Line: A Review
- B. Déruelle, C. Moreau, +5 authors A. Nono
- Geology
- 1991
Since the work of Von Baumann (1887) the Cameroon Line (Fig. 1) is known as a major geological feature in Central Africa. The Cameroon Line is an alignment of oceanic and continental volcanic massifs… Expand
Iodine abundances in oceanic basalts: implications for Earth dynamics
- B. Déruelle, G. Dreibus, A. Jambon
- Geology
- 1 February 1992
Abstract Iodine analyses by neutron activation have been performed on 32 oceanic basalts glasses, 1 phonolite and 3 subaerial arc basalts. The world-wide sample set encompasses all typical geodynamic… Expand
Regional O-, Sr-, and Pb-isotope relationships in late Cenozoic calc-alkaline lavas of the Andean Cordillera
- R. Harmon, B. Barreiro, +6 authors J. A. Viglino
- Geology
- Journal of the Geological Society
- 1 September 1984
Quaternary-Recent volcanism in the Andes has occurred in three regions: 45–33°S, 28–16°S and 2°S–5°N, each of which has a distinct plate tectonic setting and contains volcanic suites with different… Expand
Mount Cameroon: an active volcano of the Cameroon Line
- B. Déruelle, J. N'ni, R. Kambou
- Geology
- 1987
Abstract Mt Cameroon is a large volcanic horst which belongs to the Cameroon Line. The morphology of the massif depends on tectonic control. Mt Cameroon is built upon a Precambrian metamorphic… Expand
Petrology of the plio-quaternary volcanism of the South-Central and Meridional Andes
- B. Déruelle
- Geology
- 1 October 1982
Plio-quaternary volcanoes lay upon a continental crust which is thick and of Precambrian-Paleozoic age in the South-Central Andes (SCA, 18–28°S) whereas it is relatively thin and of Mesozoic-Cenozoic… Expand
Petrology of the bimodal Cenozoic volcanism of the Kapsiki plateau (northernmost Cameroon, Central Africa)
- I. Ngounouno, B. Déruelle, D. Demaiffe
- Geology
- 1 October 2000
The Kapsiki Plateau is the northernmost volcanic zone of the Cameroon Line. The volcanism (27‐35 Ma) is of alkaline type and has a typical bimodal lava series diversity with basalts and hawaiite as… Expand
Petrology of the Mio-Pliocene volcanism to the North and East of Ngaoundéré (Adamawa, Cameroon)
- O. F. Nkouandou, I. Ngounouno, B. Déruelle, D. Ohnenstetter, R. Montigny, D. Demaiffe
- Geology
- 2008
Basaltic flows and thirty-five plugs of felsic alkaline volcanic rocks (phonolites and trachytes) of Mio-Pliocene age are exposed to the north and east of Ngaoundere (Adamawa, Cameroon). The series… Expand
