As part of Central Asian Orogenic Belt(CAOB), the Central Tianshan zone plays a crucial role in the reconstruction of the tectonic evolution of the CAOB. Furthermore, it is bordered by the Tarim Craton to the south, and the comparable evolutionary history between them enables the Central Tianshan zone to provide essential information on the crustal evolution of the Tarim Craton. The eastern segment of the Central Tianshan tectonic zone is characterized by the presence of numerous Precambrian metamorphic rocks,among which the Xingxingxia Group is the most representative one. The granitoids gneisses, intruded into the Xingxingxia Group, consist of two major lithological assemblages:(1) biotite-monzonitic gneisses and(2) biotite-plagioclase gneisses. These metamorphosed granitoid rocks are characterized by enrichment in Si O2, Al2O3 and K2O and depletion in Mg O and Fe O T. The Rittmann index(r) spreads between 1.44 and2.21 and ACNK(Al2O3/(Ca O + Na2 O + K2O)) ranges from 1.03 to 1.08, indicating that these granitoid gneisses are high-K calc-alkaline and peraluminous. Trace element data indicate that the studied samples are enriched in LREE with moderate REE fractionated patterns((La/Yb)N= 10.5–75.3). The concentrations of HREE of the garnet-bearing gneisses are significantly higher than those of garnet-free gneisses. The former show pronounced negative Eu anomalies(Eu/Eu*= 0.32–0.57), while the latter are characterized by negligible negative Eu anomalies to moderate positive Eu anomalies(Eu/Eu*= 0.80–1.35). In addition, the enrichment of LILE(Rb, Th, K, Pb) and depletion of HFSE(Ta, Nb, P, Ti) of the examined granitoid gneisses are similar to typical volcanic-arc granites. Zircons U–Pb dating on the biotite monzonitic gneiss yields a weighted mean206Pb/238 U age of 942.4 ± 5.1 Ma, suggesting their protoliths were formed in the early Neoproterozoic, which is compatible with the time of the assembly of supercontinent Rodinia. The zircons have a large e Hf(t) variation f

The Dunhuang Block,located in the eastern Tarim Craton,widely exposes Precambrian TTG gneisses and metamorphosed supracrustal rocks.A suite of metasedimentary rocks of the Dunhuang Group in the Hongliuxia area on the eastern margin of the Tarim Craton are characterized by moderate contents of quartz,plagiodase,and biotite,with minor amounts of garnet or kyanite,most of which have experienced strong deformation,resulting in welldeveloped amphibolite-facies *** examined samples are characterized by moderate FeO+MgO and TiO contents,and AlO/SiO and KO/NaO ratios with low Chemical Index of Alteration(CIA)and high Index of Compositional Variability(ICV)values,suggesting that the protolith sediments originated from continental island arc *** U-Pb ages of magmatic-type detrital zircons from the Hongliuxia metasedimentary rocks range between 2476 Ma and 1950 Ma,with a peak at 2417 *** zircons of metamorphic origin yielded an age peak at 1832 Ma,which may represent a tectono-thermal event in the Paleoproterozoic,Considering that the main age populations of the analyzed samples are consistent with the tectono-thermal events in the Tarim Craton during the early Paleoproterozoic,we propose that the Tarim Craton was possibly the major source for the protolith sediments of the metasedimentary rocks in the Hongliuxia area,Zircon Hf isotopic compositions (ε(t)=-5.8 to+2.9)suggest voluminous addition of juvenile materials to the crust and minor reworking of old materials in the eastern Tarim Craton during the Mesoarchean(T=2.8-2.9 Ga).The metasedimentary rocks of the Hongliuxia area provide dear constraints to the evolution of the Tarim Craton,A possible tectonic model is that multiple thermal events(～2.4 Ga,2.2 Ga,2.0 Ga and 1.8 Ga)occurred in the study area,and the time period of Mesoarchean was important for crustal growth in the eastern Tarim Craton,whereas the～1.83 Ga metamorphism might represent a thermal event assodated with the Tarim Craton wit

The Chinese Altai–East Junggar collage in southern Altaids is one of the largest and most important metallogenic provinces in China. It is composed of five major types of Middle to Late Paleozoic metal deposits:(1) VMS Cu–Pb–Zn,(2) porphyry Cu–Au,(3) magmatic Cu–Ni-sulfide,(4) skarn Cu–Mo–Fe and(5) orogenic Au. Tectonically, the development of these metal deposits was closely associated with accretionary and convergent processes that occurred along the southern margin of the Central Asian Orogenic Belt(CAOB). The formation of the deposits involved three main stages, briefly described as follows:(i) Those formed during extensional back-arc volcanism along the Paleozoic active margin of the CAOB. They are Late Devonian to Early Carboniferous polymetallic volcanogenic massive sulfide deposits, together with some broadly contemporaneous Fe–Cu skarns, located in the accreted Qiongkuer-Talate Terrane in the western Altai;(ii) Carboniferous to Permian terrane accretion and arc magmatism, resulting in widespread metalliferous ores of different types such as copper-bearing porphyries and Alaskan-type Cu–Ni–PGE zoned ultramafic bodies developed in arcs in the Buerjin-Ertai and Erqis terranes, and Cu–Fe skarns formed in the Erqis flysch basin;(iii) Continuing accretion in the Permian leading to the development of the Dulate arc in the southern Altai associated with the formation of Cu–Mo skarns and orogenic-type gold vein systems. The Chinese Altai–East Junggar collage typically demonstrates the various classic metalliferous ores formed during the processes of subduction-accretion and arc generation.

Different genotypes of Bambara groundnut (Vigna subterranea L. Verdc) grow well under conducive environmental conditions, provided that adequate soil moisture is available during vegetative and reproductive phases. However, drought stress is the major limiting factor to bambara production, which accounts for up to 40% of yield losses. This situation could worsen due to drastic and rapid changes in the global climate. Landraces grown by farmers are low-yielding. Understanding the physiological response of different genotypes to drought stress is key to achieving food security through crop improvement and diversification. This study focused on variations in the response of Bambara groundnut genotypes to intermittent drought stress during the crop’s critical growth (vegetative and reproductive) stages. The experiment was undertaken at CSIR-Crops Research Institute Screen-house. The treatments were used in a factorial experiment with three replications in a randomized complete block design. The Bambara genotypes showed considerable variability in tolerance to drought stress. Drought stress during vegetative and reproductive stages significantly reduced crop growth indices, the leaf relative water content, chlorophyll content and leaf area. Drought stress during vegetative and reproductive stages had a more severe impact on the seed yield of genotype Nav Red, reducing it by 69% and 13%, respectively. Farmers should pay more attention to adopting drought-tolerant and high-yielding varieties for improved Bambara groundnut productivity and livelihoods.

The Dunhuang Block, located in the eastern margin of the Tarim Craton, possesses a wealth of information about the geological evolution of the Tarim Craton. In this study, we conducted detailed petrological,geochemical and geochronological investigations on garnet-bearing amphibolites as well as granites in the Dunhuang Block, which record important metamorphic and magmatic events that are poorly constrained. Based on field occurrence, geochronological and geochemical characteristics, the garnetbearing amphibolites can be divided into two groups. Group I garnet-bearing amphibolite displays typical features of island arc basalts, which may formed at ～1.83 Ga in a collisional setting during the assembly of the Columbia supercontinent, whereas group II has geochemical characteristics of ocean island basalt which may formed at ～1.61 Ga in an ocean island setting. The ca. 1.83 Ga amphibolite has positive εHf(t)values(+4.4 to +8.9), with T DM1 model ages of 2.02–1.83 Ga, indicating an important addition of juvenile mantle-derived materials during the formation of its protolith. The ca. 1.61 Ga amphibolite has εHf(t)values ranging from-0.6 to +5.6 and corresponding T DM1 model ages varying from 2.03 Ga to 1.84 Ga,which suggest that juvenile mantle-derived materials were dominantly contributed to the formation of its protolith but were later contaminated by crustal materials. The U–Pb ages obtained from the rims of the zircon grains in amphibolites and granites recorded a tectonothermal event at ca. 400 Ma, which is coeval with the widespread magmatism in the Beishan orogen. We thus propose that these two groups of garnetbearing amphibolites were possibly not related to each other during Paleoproterozoic time, and a late Paleozoic orogenic event brought them together during which both of them underwent metamorphism.

Geochemical behavior of lithium(Li) in mantle processes is generally explained by:(1) Li diffuses into minerals from melts,faster in clinopyroxene than in olivine,creating isotopically lighter-Li clinopyroxene and heavier-Li olivine;(2) Partitioning of Li changes with temperature,and as cooling proceeds Li diffuses into clinopyroxene from olivine,also resulting in low-δLi clinopyroxene and high-δLi olivine,similar to the result of process(1),Our results obtained from highly carbonatite-metasomatized peridotite xenoliths from the Western Qinling reveal that the minerals of these xenoliths contain extremely high Li in a range of 2-16 ppm for olivine,2-43 ppm for orthopyroxene,and up to 75 ppm for ***,olivines have much lower 6’Li(down to - 42‰) relative to co-existent *** observations provide important insights into the behavior of Li during mantle *** explanation is that the fractionation of Li strongly depends on the metasomatic *** melts,particularly Na-rich carbonatitic melts,which have high Li contents(-200 ppm) but mantle levelδLi(3-5‰),tend to effectively transfer Li into olivine and Li into pyroxene,while silicate melts behave on the *** might be the existence of a reservoir with a high Li content but lowδLi,like eclogite,in the mantle since the Li released into the overlying mantle wedge during *** study reveals the disLinctive behavior of Li between the carbonatite and silicate metasomatism in the mantle.

The Xiadong ma fic–ultrama fic complex is located in the Central Tianshan Terrane, the southern part of the Central Asian Orogenic Belt. It is composed of dunite, hornblende clinopyroxenite, hornblendite and hornblende gabbro. Several dykes of hornblendite, hornblende gabbro and gabbroic diorite cut the main body. These rocks are characterized by adcumulate textures. The dunites contain high-Fo(92.3–96.6) olivines with rare orthopyroxene and plagioclase. Hornblende, chromite, and magnetite are common phases in all of the rock types. Geochemically, the rocks of the Xiadong complex display high Mg O contents and extremely low trace element abundances. Although the rocks of the main body show higher Mg O contents and lower trace element abundance compared to the dykes, both are characterized by flat REE patterns and enrichment of LILE relative to HSFE. These petrological, mineralogical and geochemical features indicate that the Xiadong complex is a typical Ural–Alaskan type complex. The cross-cutting and intrusive relationships of the rock units and their distinct geochemical features suggest that the main body represents a different pulse from the intrusive dyke. The positive whole-rock εNd(t) values, together with variable(87Sr/86Sr)i ratios, show a depleted mantle source metasomatized by subduction-related material. Zircon U–Pb dating on one hornblende gabbro from the main body of the complex yields a U–Pb206Pb/238 U age of 479 Ma, and zircons from three samples of the dykes yield ages of 477, 379 and 313 Ma. All the zircons have positive εHf(t) and slightly higher δ18O than normal mantle, and their Hf–O isotopic values are correlated to their ages. The older samples are comparable to those from the Permian ma fic–ultrama fic complexes in the Beishan Terrane, which were derived from a mantle source metasomatized by subduction of the South Tianshan ocean, while the younger samples are similar to those from the Paleozoic complexes in the Eastern Tianshan, which record

The Gongchang iron deposit, a typical Algoma-type banded iron formation(BIF) deposit located in the Eastern Block of the North China Craton(NCC), is hosted in Neoarchean metamorphic rocks, including amphibolite, biotite leptynite, garnet biotite schist, plagioclase-hornblende schist, garnet chlorite schist,muscovite quartz schist and actinolite magnetite quartzite. Geochemical data suggest that protoliths of the amphibolites and biotite leptynite should be basalt and dacite, respectively. SHRIMP U–Pb dating of zircons from the plagioclase-hornblende schist shows that the Gongchangling iron deposit was formed at 2554 ± 12 Ma. Major elements and REE data of the ores indicate that the Gongchangling BIF precipitated from seawater, and the ultimate iron and silica origins may have been related to nearby volcanic activity. The 18 O values of quartz from the BIFs range between 9.1 and 12.9‰, suggesting that exotic high 18 O fluids were involved during metamorphism. The pyrite have 34 S values of range between-3.5‰ and 14.7‰, suggesting that mineralization were originally from metamorphism. Comparison of the mineralization age of the Gongchangling BIF with those of other local BIFs in North China and other cratons throughout the world indicates that the Gongchangling BIF formed coevally with the global BIF mineralization at ～2.5 Ga. Taken together, these data suggest that the Gongchangling iron deposit was formed in a volcanic submarine environment in which hydrothermal fluids associated with volcanic activity supplied both iron and silica for the banded iron formations.
