Trace Elemental Expression in Soil Substratum and Floral Species in Selected Lateritic Profiles in the Northern Part of Kolar Schist Belt, Dharwar Craton, India

Autor: B. N. Rashmi, B. C. Prabhakar, R. V. Gireesh

Publikováno v: International Journal of Geosciences. :1004-1024

Extensive laterite cappings are observed in the northern part of Kolar schist belt and they are underlain by pillowed metabasalt and partially weathered auriferous cherty intercalations. To appraise the possible distribution of trace elements in both

A Preliminary Biogeochemical Study over the Uraniferous Quartz-Pebble—Conglomerate Zone near Kalasapura, Chickmagalur District, Karnataka, Southern India

Autor: B. C. Prabhakar, B. N. Rashmi, R. V. Gireesh

Publikováno v: International Journal of Geosciences. :987-992

Quartz-pebble-conglomerate (QPC) bearing unconformable zone at the base of Bababudan Group of rocks in Dharwar Craton in southern India is well known for its stratigraphic significance and uraniferous nature. Over this QPC zone, soil cover is very th

Coeval felsic and Mafic Magmas in neoarchean calc-alkaline magmatic arcs, Dharwar craton, Southern India: Field and petrographic evidence from mafic to Hybrid magmatic enclaves and synplutonic Mafic dykes

Autor: R. V. Gireesh, Takashi Miyazaki, Mudlappa Jayananda, Kowete-U. Sekhamo

Publikováno v: Journal of the Geological Society of India. 84:5-28

We present field and petrographic data on Mafic Magmatic Enclaves (MME), hybrid enclaves and synplutonic mafic dykes in the calc-alkaline granitoid plutons from the Dharwar craton to characterize coeval felsic and mafic magmas including interaction o

Geochronological constraints on Meso- and Neoarchean regional metamorphism and magmatism in the Dharwar craton, southern India

Autor: Kowe-u Kapfo, Mudlappa Jayananda, T. Kano, R. V. Gireesh, Takashi Miyazaki, Hiroshi Hidaka, Tushipokla, Yukiyasu Tsutsumi

Publikováno v: Journal of Asian Earth Sciences. 78:18-38

This contribution addresses the time framework of the regional metamorphism in the three crustal provinces making the Archean Dharwar craton. We present results of texturally controlled in situ EPMA chemical dating of monazites, chemical dating of mo

Deformation pattern and vein development in Delhi Supergroup rocks, northeastern part of Delhi-Aravalli belt: Implication of late stage dilation

Autor: R. V. Gireesh, A. M. Bhola, G. K. Dinkar

Publikováno v: Journal of the Geological Society of India. 81:158-166

The Delhi Supergroup rocks of Mesoproterozoic age in the north-eastern part of Delhi-Aravalli belt are polydeformed. These rocks show meso and micro-scale stretched quartzo-feldspathic veins in the gneissic rocks in association with marble and amphib

Anatomy of 2.57 - 2.52 Ga granitoid plutons in the eastern Dharwar craton, southern India: Implications for magma chamber processes and crustal evolution

Autor: Mudlappa Jayananda, Kowete-U. Sekhamo, R. V. Gireesh

Publikováno v: Episodes. 35:398-413

We present results of field studies for magmatic processes of 2.57-2.52 Ga calc-alkaline plutonic bodies from three corridors in the eastern Dharwar craton (EDC) corresponding to different crustal levels. At deeper levels plutons are bounded by thick

Synplutonic mafic dykes from late Archaean granitoids in the Eastern Dharwar Craton, southern India

Publikováno v: Journal of the Geological Society of India. 73:117-130

We present a first overview of the synplutonic mafic dykes (mafic injections) from the 2.56–2.52 Ga calcalkaline to potassic plutons in the Eastern Dharwar Craton (EDC). The host plutons comprise voluminous intrusive facies (dark grey clinopyroxene
