Journal ArticleDOI
A Rodinian suture in western India: New insights on India-Madagascar correlations
C. Ishwar-Kumar,B.F. Windley,Kenji Horie,Takenori Kato,Tomokazu Hokada,Tetsumaru Itaya,K. Yagi,C. Gouzu,Krishnan Sajeev +8 more
TL;DR: In this article, the authors report detailed evidence for a new paleo-suture zone (the Kumta suture) on the western margin of southern India, which contains garnet-biotite, fuchsite-haematite, chlorite-quartz, quartz-phengite schists, biotite augen gneiss, marble and amphibolite.
Journal ArticleDOI
Archean tectonics and crustal evolution of the Biligiri Rangan Block, southern India
R.T. Ratheesh-Kumar,M. Santosh,M. Santosh,Qiong-Yan Yang,Qiong-Yan Yang,C. Ishwar-Kumar,Nengsong Chen,Krishnan Sajeev +7 more
TL;DR: In this article, the authors investigate the tectonic evolution of one of the northernmost block- the Biligiri Block (BRB) through a multidisciplinary approach involving field investigation, petrographic studies, LA-ICPMS zircon U-Pb geochronology, Hf isotopic analyses, metamorphic P-T phase diagram computations, and crustal thickness modeling.
Journal ArticleDOI
India–Madagascar paleo-fit based on flexural isostasy of their rifted margins
R.T. Ratheesh-Kumar,C. Ishwar-Kumar,Brian F. Windley,T. Razakamanana,Rajesh R. Nair,Krishnan Sajeev +5 more
TL;DR: In this paper, the elastic thickness (Te) and Moho depth data were used to estimate the configuration of the Moho/Crust-Mantle Interface that reveals regional correlations with the thickness variations.
Journal ArticleDOI
Mesoproterozoic suturing of Archean crustal blocks in western peninsular India: Implications for India-Madagascar correlations
C. Ishwar-Kumar,M. Santosh,M. Santosh,Simon A. Wilde,Toshiaki Tsunogae,Toshiaki Tsunogae,Tetsumaru Itaya,B.F. Windley,Krishnan Sajeev +8 more
TL;DR: In this article, the authors present the results from an integrated study of the structure, geology, petrology, mineral chemistry, metamorphic P-T conditions, zircon U-Pb ages and Lu-Hf isotopes of metasedimentary rocks from the two sutures.
Journal ArticleDOI
Linking monazite geochronology with fluid infiltration and metamorphic histories: Nature and experiment
J.R. Shazia,Daniel E. Harlov,Katsuhiko Suzuki,S.W. Kim,M. Girish-Kumar,Yasutaka Hayasaka,C. Ishwar-Kumar,B.F. Windley,Krishnan Sajeev +8 more
TL;DR: In this paper, the age of a monazite-leucosome experiment at 800 degrees C and 2 kbar has been shown to be within the error bars of a mean age of 530 Ma within error bars.
