Melt Enhanced Deformation in Migmatites of Higher Himalayan Crystallines (HHC), India
Authors: Singh Sandeep , Kushwaha Aman 
Published: January 2023

Abstract
Migmatites of Higher Himalayan Crystallines (HHC) along different river valleys are present above the Vaikrita Thrust in the upper package. They have experienced anatexis and protracted growth of in situ melt between ca. 46 Ma and ca. 20 Ma. Melt-filled conjugate set of extensional crenulation cleavage (ECC) of late-stage deformation indicating extension parallel to the preexisting foliation (Sm) and shortening normal to foliation plane. The field evidence indicates that ECC was formed during partial melting and later filled by the melt. During partial melting, the deformation got enhanced because of the accumulation of strain due to the prolonged presence of melt. That caused the increase in the melt pressure eventually leading to crossing the critical limit and forming extensional crenulation cleavage and making it the conduit for the emplacement of melt within the migmatite zone. The phenomenon of melt-filled ECC is due to melt-enhanced deformation occurring at the time of orogen parallel extension. The presence of episodic fluxing of melt as evident from U-Pb ages of zircon is very well be correlated with the building up of partial melt leading to an increase and drop of the melt pressure due to draining followed by rising of melt from the system along with the newly formed ECC until the next event. This episodic nature of fluxing appears to be a convenient mode to extract melt from partially melted terrains of migmatites leading to chaotic structures.

Abstract
Gold mineralization associated with quartz veins and sulfide minerals has been reported in Banded Iron Formation (BIF) at Girar, Bundelkhand Craton, India. The BIF is deformed with the development of tight-isoclinal folds in high strain zones and hosts four types of quartz veins viz., (i) folded veins, (ii) band parallel veins, (iii) low angle cross-cutting veins, and (iv) high angle crosscutting veins. Folded and band parallel veins are continuous with each other and spatially restricted to zones of tight-isoclinal folds in BIF. Shape of quartz aggregates in the folded and band parallel veins is interlobate, and these veins contain pyrite and chalcopyrite as dominant sulfide minerals along with gold. Microstructure of quartz grains and presence of fragments of BIF in sulfide mineral-gold bearing folded and band parallel veins indicate that the formations of these veins were related to a single deformation episode. Spatial association of folded and band parallel veins to intensely folded zones in BIF is attributed to epigenetic nature of sulfide and gold mineralization.
Petrologic Evolution of Post-collisional Magmas of Spinel-lherzolite Subcontinental Mantle Contaminated by Continental Crust; Palandöken (Erzurum) Volcanic Rocks in the East Anatolia, Turkey
Authors: Kürüm S. , Sar A. , Nas N. 
Published: January 2023

Abstract
The Palandöken volcanics are made up of a thick volcanic sequence consisting dominantly of tuffs and intercalated lava flows in Erzurum-Tekman basin. According to the data obtained from geochemical analyses, the silica contents of the lavas range from 47.44 % (basalt) to 67.68 % (dacite) and Mg# 11-53%. While alkaline (latite and benmoreite) and subalkaline lavas are generally enriched in large ion lithophile elements (LILE) and light rare earth elements (LREE) in conformity with each other, they show significant negative Nb, Ta anomalies and very weak Eu anomaly. There are also examples (N15, N19) in these rocks that differ in their elements behavior. These geochemical characteristics indicate that, starting from the source magma, various differentiation processes like magma mixing and melt effect, occurred. Whereas the Nd (143Nd/144Ndi) isotope values of the volcanic rocks vary in a narrow range of 0.51281 and 0.51267, Sr isotope (87Sr/86Sri) values have a relatively wider range between 0.70362 and 0.70500, and εNd(t) values (+0.71 to +5.14). Isotope and geochemical data; supports that these volcanics were formed by the partial melting of spinel-lherzolite subcontinental lithospheric mantle-derived magma at different rates, but assimilation of continental crust also played an important role, along with magma mixing and fractional crystallization, which constitute the main differentiation process.
Palandöken volcanic rocks have similar geochemical characteristics with the nearby Ilica, Kandilli and Yolçatý volcanics in general and their properties are compatible with eastern Anatolian magmatism that was formed in a geodynamic setting of post-collisional extension.

Abstract
Mining of Coal is one of the chief sources of power generation globally to meet the energy demand. However, the mining operations and power production leads to the generation of overburdens and fly ash in huge quantities. These became severe threat to the environment during backfilling via leaching of contaminants and forming acid mine drainages. To understand the chemical characteristics of overburden, seven locations from the Ib valley coalfield were sampled. Also, a fly ash sample was collected from NTPC, Kaniha, Odisha. Subsequently, laboratory-based experiments were conducted under controlled condition to estimate the leachate characteristics of the overburden and overburden-fly ash (30%) composite samples through various leaching agents viz., distilled water, rain water and 0.1N acetic acid. Overburden samples were found to be slightly acidic in nature, whereas fly ash was almost neutral. The mean concentration of the metals in the OBs showed a decreasing trend of Fe&gt;Al&gt;K&gt;Mg&gt;Ca&gt;Na&gt;Mn&gt;Cr&gt;Cu&gt; Zn&gt; Co&gt;Ni&gt;Cd&gt;Pb. The leachability potential is found to be high with acetic acid followed by rainwater and distilled water. The estimated possible total metal leachate from the 0.1% (0.1219 Million tonnes) of total overburden generated during 2017-18 in Mahanadi coalfields (MCL) was found to be 0.00023%. The results from the metal indices i.e. contamination factor showed that the overburdens are critically contaminated with Se followed by Cd, As and Cu, as their associated shale have quite low values. Also the potential ecological risk (PER) for the overburdens is low if Se, Cd, and Cu are excluded.

Published: January 2023

Abstract
Detailed petrographic, dense minerals and petrofacies investigations were performed on forty nine medium-to fine grained, well-cemented and moderately to well-sorted sandstone samples from the Joyan Member of the Jaisalmer Formation. The grains are sub-angular to sub-rounded in shape, with some well-rounded quartz grains. The framework composition of sandstone consists mostly of monocrystalline and polycrystalline quartz, low-to high-grade metamorphic and sedimentary rock fragments, as well as subordinate feldspar with low plagioclase to total feldspar ratios and accessory minerals. Petrographic investigations reveal that sandstones from the Joyan Member of the Jaisalmer Formation are sublitharenite to litharenite. The sandstone composition suggests that the detritus are derived from the metamorphic, plutonic-volcanic felsic, and recycled sedimentary rocks. Dense mineral analyses also confirm the possibility of mixed provenance for the Joyan Member Sandstone. The sandstone petrofacies indicates their derivation from cratonic interiors, as well as recycled orogenic and quartzose recycled provenances under humid climatic conditions. The petrographic, sedimentological, and dense mineral analyses in agreement with palaeocurrent data suggest that the Joyan Member Sandstone was primarily derived from Erinpura-Godhra-Mount Abu-Sirohi (Balda) granites and Malani volcanics, with a contribution from Archean Aravalli (Berach) granitoids and Aravalli and Delhi orogens. The shift in sediment supply from Aravalli (Berach) granitoids and Aravalli and Delhi orogens to Erinpura-Godhra-Mount Abu-Sirohi (Balda) granites and Malani volcanics supports sedimentation in a tectonically active basin.

Abstract
The groundwater level (GWL) declination is the critical problem in the Rajasthan. So, the implementation of appropriate groundwater (GW) management strategies are required in the Rajasthan state. Before that, it is necessary to know the areas where these are essential and for that identification of critical locations and their prioritization is very important. In the present study, innovative approach is used for prioritization of divisions and districts in these prioritized divisions (PRDIVs) of the Rajasthan. Innovative approach is applied by analyzing trends in the four seasonal GWL time series. Results showed that, in north-eastern, eastern and central Rajasthan, significant declination in GW and significant increasing trends in GWLs is observed in some districts corresponding to all seasons. Also, divisions are prioritized as: Jaipur, Bharatpur, Udaipur, Ajmer, Jodhpur, Kota and Bikaner, with first division having highest priority, second is having 2nd highest priority and so on. Prioritized districts in corresponding PRDIVs are also identified.

Published: January 2023

Abstract
The small Indian mongoose, Urva auropunctata, is one of the most notorious invasive species in the world. In Japan, the mongoose was introduced to Amami, Kyushu (Kiire region), and Okinawa Islands. Currently, an eradication program for the Amami population is proving successful. To prevent reinvasion and conserve biodiversity, it would be advantageous to investigate the origin and dispersal history of introduced mongoose populations in Japan. We determined the mitochondrial genome of a mongoose from the Okinawa population and confirmed that the systematic status of the mongoose is Urva auropunctata. We also found two haplotypes of cytochrome b in the Amami population, one of which is common among the Okinawa, Amami, and Kiire populations. Based on our microsatellite analysis, the three populations were genetically different from each other. Furthermore, with a low pairwise FST value, the Kiire population was closer to the Okinawa than the Amami population. Our results suggest that the Okinawa population could be the source of the Amami and Kiire populations. These results align with historical records of mongoose in Japan and clarify its genetic status. Our results should aid the prediction of the pathway through which a new invasion will likely occur.

Published: January 2023

AbstractFlexible microelectronic devices have seen an increasing trend toward development of miniaturized, portable, and integrated devices as wearable electronics which have the requirement for being light weight, small in dimension, and suppleness. Traditional three-dimensional (3D) and two-dimensional (2D) electronics gadgets fail to effectively comply with these necessities owing to their stiffness and large weights. Investigations have come up with a new family of one-dimensional (1D) flexible and fiber-based electronic devices (FBEDs) comprising power storage, energy-scavenging, implantable sensing, and flexible displays gadgets. However, development and manufacturing are still a challenge owing to their small radius, flexibility, low weight, weave ability and integration in textile electronics. This paper will provide a detailed review on the importance of substrates in electronic devices, intrinsic property requirements, fabrication classification and applications in energy harvesting, energy storage and other flexible electronic devices. Fiber- and textile-based electronic devices for bulk/scalable fabrications, encapsulation, and testing are reviewed and presented future research ideas to enhance the commercialization of these fiber-based electronics devices.

AbstractIn the last few years, 3D printing has evolved from its original niche applications, such as rapid prototyping and hobbyists, towards many applications in industry, research and everyday life. This involved an evolution in terms of equipment, software and, most of all, in materials. Among the different available 3D printing technologies, the light activated ones need particular attention from a chemical point of view, since those are based on photocurable formulations and in situ rapid solidification via photopolymerization. In this article, the chemical aspects beyond the preparation of a formulation for light-induced 3D printing are analyzed and explained, aiming at giving more tools for the development of new photocurable materials that can be used for the fabrication of innovative 3D printable devices.

Published: January 2023

AbstractZn-based alloys have found increasing interest as orthopedic biodegradable implantable materials, hence it was the aim of this work to investigate the microstructure and corrosion behavior of Zn–0.5Al–xMg cast alloys with different Mg additions in simulated body fluid (SBF). The cast samples were prepared using a simple stir casting method and the molten alloys were poured in a cast iron mold. The SEM results showed that adding Mg greatly influenced the microstructure of the Zn-based alloys where the degree of fineness of the microstructure increased with a rise in the Mg content. Moreover, polarization measurements revealed that the Zn–0.5Al–0.6Mg alloy attained the lowest degradation rate of 0.33 mm/year as compared to the other investigated alloys which complies the requirements of ideal corrosion rates for biodegradable bone implants. This corrosion rate helps the implantable metal alloy to last in the body until healing of the bone tissue proceeds. The fine structure and uniform distribution of Aluminum oxide and MgZn2 intermetallic phases along the grain boundaries were most likely the main factors in the superior corrosion stability of the Zn–0.5Al–0.6Mg alloy in SBF. However, higher concentrations of Mg (1 wt%) lowered the corrosion resistance of the Zn–Al–Mg alloy which was attributed to the accelerated galvanic corrosion between Zn and Mg2 Zn11 phases and the inhomogeneous distribution of corrosion products on the alloy surface due to the increased grain size and the coarse structure of the Zn alloy.

AbstractIn this work, the effects of CoxZn1-xFe2O4(x= 0, 0.5, 1) nanofillers on the PVDF polymer were scientifically studied. The structure and magnetic and optical properties were studied. XRD confirms the synthesis of nanofiller in a single phase. FTIR confirms the formation of nanoferrites. HRTEM shows that the prepared nanoferrites have a cubic-like shape. Also, the size and agglomeration increase with Co-Zn Fe2O4nanoferrites compared to the other singles one. The effect of adding nanoferrites into PVDF matrix was studied using XRD, FTIR, FESEM, VSM, and UV-Vis. XRD and FTIR approved the complexation between PVDF polymer and nanoferrites. Also, addition of nanoferrites into PVDF leads to decrease the semi-crystalline nature of PVDF. FESEM showed that embedding nanoferrites into PVDF polymers creates pores and PVDF/Co-Zn Fe2O4increases the pore size on the PVDF surface. The magnetic properties of PVDF were enhanced by adding the nanofiller. For example, saturation magnetization was increased from 269.31E−6to 62.052E−3by adding CoFe2O4to PVDF polymer. Band gap calculation showed that PVDF/Co-Zn Fe2O4has the lowest band gap energy which makes it useful in photochemical and electronic applications.
