“…Paleostress analysis using fault-slip data from lower Cuddapah lithounits around these faults indicate strike-slip to extensional tectonic regimes, suggesting fault controlled initiation of the Kurnool sub-basin (Tripathy and Saha, 2013). These analyses along with the occurrence of intracratonic alkaline magmatism in the Eastern Dharwar craton during the late Mesoproterozoic, e.g.…”

“…However, faults such as Gani-Kalva and Kona faults ( Fig. 1), affect the older succession (Chitravati Group) as well as the younger stratigraphic units of the Kurnool Group with indications of fault reactivation (Tripathy and Saha, 2009;Saha and Tripathy, 2012;Tripathy and Saha, 2013). The multiple events of brittle to brittle-ductile deformational imprint, particularly mechanical twins in calcite, in the neighborhood of Gani-Kalva and Kona faults are analysed here to understand their significance in contemporaneous local and regional tectonics.…”

“…Based on outcrop scale fault-slip criteria such as stratigraphic offset, slickensides, rough and smooth surface, tension gashes, fault related folds, fault drag, normal faults along releasing bend and outcrop scale faults, the GKF has been shown as having oblique normal sense of displacement with maximum footwall throw in the west, that progressively diminishes toward the east ( Fig. 2; Tripathy and Saha, 2013). The fault at its westernmost part cuts through the basement granite gneiss around Veldurti.…”

“…1a), is one of the largest of the Purāna (Holland 1907) Paleo-to Meso-Proterozoic sedimentary basins of India. It has been extensively studied for well over a century with regard to its structure, tectonics, igneous activity, sedimentation, stratigraphy, geochronology and mineral wealth (e.g., King 1872; Nagaraja Rao et al 1987;Anand et al 2003;Chetty 2011;Patranabis-Deb et al 2012;Tripathy and Saha 2013;Basu and Bickford 2013;Bickford et al 2013;Collins et al 2014;Deb and Pal 2014). Despite these studies, the origin and evolution of the Cuddapah Basin still remains unclear with diverse models in vogue viz.…”

Petrogenesis of Mesoproterozoic lamproite dykes from the Garledinne (Banganapalle) cluster, south-western Cuddapah Basin, southern India

et al. 2015

We report mineral chemistry and whole-rock major and trace-element geochemistry for a recent find of Mesoproterozoic (~1.4 Ga) lamproites from the Garledinne (Banganapalle) cluster, south-western part of the PaleoMesoproterozoic Cuddapah Basin, southern India. The Garledinne lamproites occur as WNW-ESE-trending dykes that have undergone varying degree of pervasive silicification and carbonate alteration. Nevertheless, their overall texture and relict mineralogy remain intact and provide important insights into the nature of their magmas. The lamproite dykes have porphyritic to weakly porphyritic textures comprising pseudomorphed olivine macrocrysts and microphenocrysts, titanian phlogopite microphenocrysts, spinel having a compositional range from chromite to rarely magnesiochromite, Srrich apatite and niobian rutile. The Garledinne and other Cuddapah Basin lamproites (Chelima and Zangamarajupalle) collectively lack sanidine, clinopyroxene, potassic richterite, and titanite and are thus mineralogically distinct from the nearby Mesoproterozoic lamproites (Krishna and Ramadugu) in the Eastern Dharwar Craton, southern India. The strong correlation between various major and trace elements coupled with high abundances of incompatible and compatible trace elements imply that alteration and crustal contamination have had a limited effect on the whole-rock geochemistry (apart from K 2 O and CaO) of the Garledinne lamproites and that olivine fractionation played an important role in their evolution. The Garledinne lamproites represent small-degree partial melts derived from a refractory (previously melt extracted) peridotitic mantle source that was subsequently metasomatised (enriched) by carbonate-rich fluids/melts within the garnet stability field. The involvement of multiple reservoirs (sub-continental lithospheric mantle and asthenosphere) has been inferred in their genesis. The emplacement of the Garledinne lamproites is linked to extensional events, across the various Indian cratons, related to the break-up of the Proterozoic supercontinent of Columbia.

A new approach for paleostress analysis, using the nine-dimensional space fault slip inversion method, was performed in the southeastern flank of the Jordan-Dead Sea Fault. Five major tectonic episodes with different kinematics were successfully detected from the inversion of a new fault slip data, which thereby caused reactivation of inherited crustal structures and established new ones. These episodes prevailed since Late Cretaceous times, and their chronological constraints were established essentially from the stratigraphic ages of the affected rocks and the crosscutting relationships of successive striae locally observed on the fault planes. During the Late Cretaceous to late Eocene, the area was under a compressional/strike-slip stress regime with a~E-W trending σ 1 . At Oligocene, a strike-slip stress regime with NW-SE striking σ 1 occurred. Both compression regimes correspond to the so-called Syrian Arc Deformation that gave rise to distinctive folds in Jordan and its surrounding areas. An extension with~N-S to NE-SW trending σ 3 followed the late Oligocene compression event and took place during Miocene time, most probably linked to the opening of the Red Sea-Suez Rift. Late Cenozoic tectonics show the occurrence of two successive compressions, NW-SE then both NE-SW and~N-S, which generally reflect a continental collisional setting between the Arabian and Eurasian plates.
