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
Late Neoarchean to early Paleoproterozoic tectonic evolution of the southern North China Craton: Evidence from geochemistry, zircon geochronology and Hf isotopes of felsic gneisses from the Taihua complex
Xiaoliang Jia,Mingguo Zhai,Mingguo Zhai,Wenjiao Xiao,Yong Sun,R.T. Ratheesh-Kumar,He Yang,Ke-Fa Zhou,Jia-Ling Wu +8 more
TL;DR: In this article, the authors present new data on petrology, zircon geochronology, whole-rock geochemistry and isotopes of TTGs, granitic gneisses and felsic leucosomes of migmatites from the Taihua complex in the Xiaoqinling area.
Journal ArticleDOI
Mesoarchean to Paleoproterozoic crustal evolution of the Taihua Complex in the southern North China Craton
Xiaoliang Jia,Xiaoliang Jia,Mingguo Zhai,Wenjiao Xiao,Liang Li,R.T. Ratheesh-Kumar,Jia-Lin Wu,Jia-Lin Wu,Yin Liu +8 more
TL;DR: In this article, the La-ICP-MS zircon U-Pb age dating and Lu-Hf isotopic analysis are applied to the orthorgneisses, felsic leucosomes, and granites of the Taihua Complex, in order to provide constraints on its crustal evolution from the Mesoarchean to Paleoproterozoic (ca. 2.90-2.8
Journal ArticleDOI
Tectonic inheritance of the Indian Shield: New insights from its elastic thickness structure
TL;DR: A new evaluation of the elastic thickness (Te) structure of the Indian Shield, derived from isotropic fan wavelet methodology, documents spatial variations of lithospheric deformation in different tectonic provinces correlated with episodic tectono-thermal events.
