Structure of the eastern margin of the East African Orogen in central Madagascar by Collins, Alan, Fitzsimons, Ian, Hulscher, B., Razakamanana, T.

“…The island of Madagascar straddles the poorly understood eastern margin of the East African Orogen, which is characterised by a high-grade gneissic basement that was structurally and thermally reworked during the Neoproterozoic collision of the Dharwar craton of India with the Congo/Tanzania/Bangweulu craton of Africa. …”

The age and petrogenesis of alkaline magmatism in the Ampasindava Peninsula and Nosy Be archipelago, northern Madagascar by Cucciniello, C., Tucker, R., Jourdan, Fred, Melluso, L., Morra, V.

“…The Ampasindava alkaline province consists of a series of circular and elliptical intrusions, lava flows, dyke swarms and plugs of Cenozoic age emplaced into the Mesozoic-Cenozoic sedimentary rocks of the Antsiranana basin (NW Madagascar) and above the crystalline basement. The magmatism in the Ampasindava region is linked to a NW-SE trending extensional tectonic setting. …”

Pan-African granulites of Madagascar and southern India: Gondwana assembly and parallels with modern Tibet by Fitzsimons, Ian

“…The highest metamorphic gradients of 25-50°C km-1 were attained at 0.58-0.53 Ga in a microcontinental block that was sandwiched between two collisional sutures and is now exposed in Madagascar and southern India. The 50 Myr duration of extreme pressure-temperature (P-T) conditions and lack of coeval mantle magmatism suggest that metamorphism was driven by radiogenic heat accumulation beneath a long-lived orogenic plateau. …”

Linking coral river runoff proxies with climate variability, hydrology and land-use in Madagascar catchments by Maina, J., de Moel, H., Vermaat, J., Bruggemann, J., Guillaume, M., Grove, C., Madin, J., Mertz-Kraus, R., Zinke, Jens

“…To achieve these, we developed models to simulate hydrology of two watersheds in Madagascar. We examined relationships between environmental proxies derived from massive Porites spp. coral cores (spectral luminescence and barium/calcium ratios), and corresponding time-series (1950–2006) data of hydrology, climate, land use and human population growth. …”

Out of Africa: detrital zircon provenance of central Madagascar and Neoproterozoic terrane transfer across the Mozambique ocean by Fitzsimons, Ian, Hulscher, B.

“…This palaeogeographic change and its environmental consequences are poorly understood, but new detrital zircon ages from Madagascar and published data from elsewhere provide evidence for multiple ocean basins and two-stage collision. …”

'Candidatus Phytoplasma malaysianum', a novel taxon associated with virescence and phyllody of Madagascar periwinkle (Catharanthus roseus). by Nejat, Naghmeh, Vadamalai, Ganesan, Davis, Robert E., Harrison, Nigel A., Sijam, Kamaruzaman, Dickinson, Matthew, Abdullah, Siti Nor Akmar, Zhao, Yan

“…This study addressed the taxonomic position and group classification of a phytoplasma responsible for virescence and phyllody symptoms in naturally diseased Madagascar periwinkle plants in western Malaysia. Unique regions in the 16S rRNA gene from the Malaysian periwinkle virescence (MaPV) phytoplasma distinguished the phytoplasma from all previously described 'Candidatus Phytoplasma' species. …”
