TL;DR: In this article, the authors investigated the weathering geochemistry and mineralogy in a lateritic soil cover in relation to the close hydrographical system at Goyoum (East Cameroon).
317 citations
TL;DR: In this paper, the role of organic colloids on mineral weathering and transport of elements in natural waters was investigated in a small catchment (Nsimi-Zoetele, Cameroon).
316 citations
TL;DR: In this paper, a statistical study of granulite facies rocks was carried out, where 32 samples with ages ranging from 2,900 to 200 Myr for Sm, Nd, Rb and Sr and 143Nd/144Nd and 87Sr/86Sr ratios.
Abstract: In a statistical study of granulite facies rocks, we have analysed 32 samples with ages ranging from 2,900 to 200 Myr for Sm, Nd, Rb and Sr and 143Nd/144Nd and 87Sr/86Sr ratios. The Sm/Nd ratio is found to be constant compared with the highly variable Rb/Sr ratio. Using the model age formalism, we show that, in many cases internal differentiation of continental crust follows external differentiation with a large time interval.

TL;DR: In this article, the results of ultrafiltration experiments (0.20 μm-300,000 Da-5000 Da-1000 Da) performed on natural rich-organic waters (30-40 mg l−1 of dissolved organic carbon) sampled in wetland area of Cameroon (Nsimi-Zoetele site).
201 citations
TL;DR: In this article, a suite of cumulate features cropping out in the mantle harzburgites of Oman are investigated. But compatible elements show that it is unlikely that all these cumulates are derived by different degrees of fractional crystallization from the same liquid.

TL;DR: In this article, a model for the Cenozoic development of the region of SE Asia and the SW Pacific is presented and its implications are discussed, accompanied by computer animations in a variety of formats.
2,272 citations
TL;DR: In this paper, the average ratio of Sm/Nd is about 0.19 in the upper continental crust, and has remained so since the early Archean, thereby precluding the likelihood of major mafic-to-felsic or felsicto-mafic trends in the overall composition of the sedimentary mass through earth history.
1,594 citations
TL;DR: The Sundaland region was assembled by closure of Tethyan oceans and addition of continental fragments in the Cretaceous and Cenozoic as discussed by the authors, and a marked change in deep mantle structure at about 110°E reflects different subduction histories north of India and Australia since 90-Ma.
777 citations
TL;DR: Paleosols (fossil soils) are preserved throughout the geologic record in depositional settings ranging from alluvial systems to between basalt flows as mentioned in this paper, and a variety of semi-quantitative and quantitative tools have been developed to examine past weathering and pedogenesis, and to reconstruct both paleoenvironmental and paleoclimatic conditions at the time that the paleosols formed.
766 citations
TL;DR: In this article, a plate tectonics model is presented to explain the tectonometamorphic characteristics of the European Variscides and the subsequent complex intracontinental deformation (380-290 Ma).
