• Naranag granites are two-mica granites exhibiting peraluminous characteristics. • Partial melting of metasedimentary sources in a syn-collisional tectonic environment. • These granites are analogous to the Pan-African thermal event. Granites represent a fundamental component of the continental crust and provide valuable insights into crustal growth, recycling, and tectono-magmatic evolution through Earth’s history. The Early Paleozoic granitoids in the Himalaya are of particular significance as they record the influence of the Pan-African event (ca. 600–500 Ma), a major tectono-thermal event related with the assembly of Gondwana. Despite the occurance of numerous Pan-African granitoids across the Himalaya, several intrusions remain poorly characterized. One such body is the Naranag granites (NG) of the northwestern Himalaya, exposed over ∼15 km² in Ganderbal District, Kashmir. This study integrates detailed field relationships, petrographic observations, and whole-rock geochemistry to investigate the petrogenesis, source characteristics, and tectonic setting of the Naranag pluton. Field observations reveal that the Naranag granites are medium to coarse grained, whitish grey, and largely undeformed, with quartz, k-feldspar, plagioclase, and biotite ± muscovite minerals present. Pegmatitic and aplitic veins with tourmaline reflect late-stage magmatic evolution. Petrographic features, including graphic textures, perthitic intergrowths, and the presence of garnet and tourmaline, confirm a peraluminous, two-mica (S-type) affinity. Geochemical analyses show high SiO₂ (68.7–70.5 wt.%), elevated alkalis (Na₂O + K₂O = 8.3–9.1 wt.%), high alumina saturation indices (ASI =1.65–1.77), and enrichment in large ion lithophile elements (e.g., Rb, Ba, K, Pb) with depletion in high-field-strength elements (e.g., Nb, Ta, Ti). These features, along with negative Ba–Sr anomalies and decreasing MgO, Al₂O₃, TiO₂, and CaO with increasing SiO₂, reflect partial melting of metagraywacke-dominated lower crust under water-undersaturated conditions, followed by fractional crystallization of feldspars and biotite. Tectonic setting plots (Rb–Y–Nb; Rb vs. Y + Nb) and calc-alkaline affinity indicate emplacement in a syn-collisional to volcanic arc setting, consistent with other Early Paleozoic granitoids of the Himalaya, such as the Hant and Dalhousie granites, and comparable Pan-African intrusions globally. The Naranag granites thus represent a crust-derived melt generated during crustal thickening and orogenic heating associated with the Pan-African tectono-thermal regime. Their geochemical affinity and mineralogical signatures provide evidence for widespread Early Paleozoic granitic magmatism across the Himalaya linked to the assembly of Gondwana. This study highlights the significance of the Naranag granites as a key but previously underexplored record of Pan-African magmatism in the northwestern Himalaya. Future isotopic and geochronological investigations are recommended to refine their emplacement age and further constrain the relative contributions of crustal versus mantle sources in their genesis.

Deciphering Magma Mingling Processes in the Zouzan Pluton, Eastern Iran: Multi-Method Constraints from Zircon Geochronology, Nd-Sr Isotopes and Amphibole-Apatite Chemistry on Mafic Enclave Formation
Seyed Ali Mazhari, Santosh Kumar
Acta Geologica Sinica English Edition, 2026
The Zouzan pluton in the Lut Block (eastern Iran) comprises coeval gabbro–diorite and felsic intrusions that contain abundant mafic enclaves (MEs). Integrated zircon U‐Pb dating, whole‐rock Sr‐Nd isotopes and amphibole‐apatite chemistry are used to investigate ME formation. Zircon ages indicate synchronous emplacement of the gabbro–diorite, MEs, and granodiorite ca. 40 Ma. The MEs plot along a Sr‐Nd isotopic mixing line between mantle‐derived gabbro–diorite and more crustally contaminated granodiorite, supporting a magma‐mixing origin. Mineral chemistry, however, reveals more complex interactions. Apatite in MEs is acicular with trace element compositions intermediate between those of mafic and felsic magmas, indicating rapid crystallisation from a hybrid melt. Amphiboles display two distinct compositional groups: one matching gabbro–diorite amphiboles and the other resembling those in the granodiorite. This bimodality suggests that ME formation involved incomplete mixing, crystal transfer between magmas and variable re‐equilibration rather than simple hybridisation. A dynamic model is proposed in which mafic magma globules were injected into a partly crystallised felsic chamber, producing mingling, quenching and crystal exchange that ultimately shaped the petrographic and geochemical features of the Zouzan pluton.

Magnetic Susceptibility and Its Correlation With Plagioclase and Whole-Rock Geochemistry of Neoarchean Granitoids From E-W Corridor of Bundelkhand Craton, Central India: Implication on Granite Series and Possible Link to Mineralization
Gajender Kumar, Santosh Kumar
Geological Journal, 2026
Based on field relationships, magnetic susceptibility (MS), phase petrology, and whole‐rock elemental geochemistry, we deduce the redox state, granite series, and mineralization potential of Neoarchean granites ( sensu lato ) from the E‐W crustal corridor of the Bundelkhand Craton, Central India. A fine‐ to medium‐grained, equigranular granites (FMEG) compositionally similar to sanukitoids are associated with mafic microgranular enclaves, whereas the high‐K, low‐magnesian, granites (HKLMG) are coarse‐grained and contain hornblende and biotite as major hydrous ferromagnesian minerals. The oxidized A‐type granites (OAG) are medium‐grained and contain biotite as only mafic mineral. A significant variation in MS value, colour, composition, and texture has been observed for the studied granites. We used MS values between Quirtile‐1 and Quirtile‐3 to reduce the external effect. The MS values for sanukitoids range from 6.34 to 11.34 × 10 −3 SI units (Avg.‐ 8.44 × 10 −3 SI units), 1.42 to 6.16 × 10 −3 SI units (Avg.‐ 4.22 × 10 −3 SI units) for HKLMG and 0.47 to 5.22 × 10 −3 SI units (Avg.‐ 1.68 × 10 −3 SI units) for OAG. The MS values and whole‐rock geochemistry of sanukitoids indicate their crystallization at elevated oxygen fugacity ( f O 2 ; −12.33 to −14.69), buffered above FMQ + 1, typically corresponding to magnetite series granites. However, the HKLMG and OAG buffered near FMQ, representing transition between oxidizing and moderate reduced f O 2 condition, corresponding to magnetite‐ilmenite series granites. High whole‐rock Nb/Ta (> 6), and Zr/Hf (> 30) ratios and plagioclase chemistry for sanukitoids suggest that the melt was water enriched and escaped fluid‐melt interaction. These granites have the potential for Cu‐Mo mineralization. In contrast, HKLMG and OAG show evidence of crustal interaction at emplacement levels, lower Fe 2 O 3 /FeO ratios (< 0.4), low MgO (< 1 wt.%), and geochemical signatures consistent with barren to weakly fertile granites. The integrated MS‐plagioclase‐geochemical framework presented here demonstrates its effectiveness in discriminating granite redox series and assessing mineralization potential in the Precambrian cratonic terrains.

Petrogenesis of Pachakkadu Pyroxenites from the Pakkanadu-Mulakkadu Alkaline Complex, Southern India: Implications on Arc-related Alaskan-type Magmatism
Rajendra Prasad Kanchi, Vittal M., V. Sai Krishna Priya, Ch. Narshimha, Lingaswamy Veeramalla, Sreenu Kunsoth, Santosh Kumar, M. Srinivas
Journal of the Geological Society of India, 2025
This study presents the field observations, petrography, pyroxene-biotite and whole-rock elemental geochemistry of pyroxenites from Pachakkadu region of Pakkanadu-Mulakkadu Alkaline Complex, Southern India, referred herein as Pachakkadu pyroxenite. At outcrop scale, the pyroxenites are engulfed into the intruding syenite magma. The pyroxenites are coarse- to medium-grained, inequigranular, cumulate rocks, modally composed of clinopyroxene (77–88 vol. %) with subordinate amphibole, biotite/phlogopite, plagioclase, and accessories like magnetite, titanite, and secondary calcite. The subordinate amount of subhedral to anhedral biotite and resorbed plagioclase, associated with coarse cumulus clinopyroxenes, most probably developed due to the assimilation of pyroxenite by the intruding syenite magma. The clinopyroxenes represent diopside and bear high Mg# (Mg/(Mg+Fe+2) = 0.71–0.74), rich in calcium (20.55–22.07 wt.%) but depleted in Na2O (1.65–2.42 wt.%) and Al2O3 (0.79–3.14 wt.%), which reveal the subalkaline, arc-related Alaskan type cumulus phase. Biotites in pyroxenites are reequilibrated primary Fe-biotites having alkaline affinity enriched in siderophyllite. Geochemically, the pyroxenites exhibit low content of SiO2 (39.50–40.48 wt. %), Al2O3 (4.58–8.34 wt. %), CaO (6.66–10.24 wt. %), and high MgO+FeO (28.56–31.26 wt. %). The total alkali content ranges from 0.48 to 2.49 wt. %. The observed variations of Ni (146.11–299.95 ppm) and Cr (652.56–4766.6 ppm) against Mg# (0.67–0.83) reflect clinopyroxene fractionation from a mantle-derived mafic magma. The evidences suggest that the Pachakkadu pyroxenites are fractionated products forming the cumulate with a minor amount of evolved intercumulus (residual) liquid as fine-grained crystals and accumulation of early fractionated minor plagioclase and Fe-Ti oxides.
