“…The Taihua Complex in the Xiaoqinling area was traditionally regarded as a meta-volcanic sedimentary sequence, and was further subdivided into the Lower and Upper Taihua "Groups" according to rock types (Qi, 1992;Guan, 1996;Ding, 1996), similar to those in the Lushan and Xiong'er areas (Huang et al, 2010(Huang et al, , 2012. The Upper Taihua "Group" consists of quartzite, metapelitic gneiss and schist, marble and iron formation, whereas the Lower Taihua "Group" consists of meta-basic volcanic rocks (amphibolite) and intermediate to felsic gneisses (biotite-plagioclase gneiss and plagioclase-amphibole gneiss), with minor granulites (Qi, 1992;Ding, 1996).…”

“…The "crustal" model ages would be 2.72-2.98 Ga (DF05-9) and 2.68-3.08 Ga (DF08-7), respectively, using the average continental crustal 176 Lu/ 177 Hf value (0.015) (Supplemental Table 3 Table 3). Zircons from (Huang et al, 2010) are shown for comparison. Data plotted based on individual apparent 207 Pb/ 206 Pb ages (t 7/6 ); line bar shows the range of data based on the crystallization age (t) of rock; the evolution of depleted mantle (DM) is drawn by using a present-day 176 Hf/ 177 Hf = 0.28325 and 176 Lu/ 177 Hf = 0.0384 (Griffin et al, 2000).…”

“…However, it still remains unknown whether or not the southern segment of the TNCO (Fig. 1a) also underwent such a long-lived subduction, though available data indicate that the Taihua and Dengfeng Complexes experienced a series of magmatic events from the Late Archean to Early Paleoproterozoic (Wan et al, 2006;Diwu et al, 2007Diwu et al, , 2011Liu et al, 2009Liu et al, , 2012aHuang et al, 2010Huang et al, , 2012.…”

“…There are many published chronological and geochemical investigations on the Taihua Complex in the Xiong'er (Diwu et al, 2007;Huang et al, 2012) and Lushan (Wan et al, 2006;Liu et al, 2009;Xu et al, 2009;Huang et al, 2010) areas, but very few reliable geochronological and geochemical studies have been done on the Taihua Complex in the Xiaoqinling area (Fig. 1b) even though it is the largest outcrop of Precambrian basement in the southern segment of the TNCO.…”

“…On the basis of Sm-Nd isochrons, depleted mantle Nd model ages, Ar-Ar dating, and single-grain zircon evaporation Pb-Pb ages, it has been suggested that the Taihua Complex in the Xiaoqinling area was comparable with other areas (BGMR, 1982;Qi, 1992;Zhou et al, 1998). However, in situ zircon U-Pb dates for the Taihua Complex in the Lushan and Xiong'er areas showed different crystallization ages (Diwu et al, 2007;Liu et al, 2009;Huang et al, 2010Huang et al, , 2012, and it is important to examine whether or not rocks in the Xiaoqinling area can be correlated with either of these areas.…”

Geochemistry of meta‐mafic and meta‐tonalite‐trondhjemite intrusives from Jaintia and Karbi Anglong hills of Shillong Plateau, North East India: Implications on the evolution of the Proterozoic Shillong Basin

We present the whole‐rock and mineral chemical data of the Khasi meta‐mafic/basic‐trondhjemite intrusives (KMI) and meta‐tonalite‐trondhjemite (MTT) that coevally emplaced the Proterozoic Shillong Group (SG) of Shillong Plateau, northeast (NE) India and discuss their petrogenetic‐tectonic origin. The calc‐alkaline to tholeiite KMI are compositionally transitional between hornblende‐gabbro; hornblende‐diorite and minor‐hornblendite. They show Ta–Nb troughs and strong decoupling large‐ion lithophile/high field strength elements (HFSE) signature consistent with subduction zone‐related basic magmas. The calcic to calc‐alkaline, low‐Al2O3, and I‐type metaluminous Fe‐hedenbergite‐trondhjemite (KMT) exhibits similar trace and rare earth elements (REE) distribution to the KMI. The MTT on the other hand are depleted in trace elements and REE, and correspond with the I‐type granitoids, and are comparable to Proterozoic to Phanerozoic tonalite‐trondhjemite‐granodiorites. Gentle negative sloping of REE in KMI ([La/Lu]CN = 4.04 to 6.35) with moderate LREE, suggests partial melting or, fractional crystallization from a transitional source between garnet and spinel lherzolite. Although almost a flat pattern ([La/Lu]CN = 3.70 to 4.05) for MTT entails a high degree of partial melting from sources similar to Archaean Mafic Composite or Archaean Tholeiite. Trace elemental modellings ([Sr/Y] vs. Y and [La/Yb]N vs. YbN) for MTT infer low pressure (<15 kbar) and high degree partial melting of >50% in equilibrium with 10% garnet +90% amphibole residue. A relatively flat REE pattern with some elevated HREE of MTT compared to KMI suggests for depleted source. Bimodal plutonism and the prevalence of meta‐dacite‐rhyolite in SG invokes for tonalite‐trondhjemite‐dacite setting of a continental arc or, active continental margin tectonic setting. Emplacement of KMI initiated in a temporary relax‐extensional phase and MTT in a compressional regime. This is possibly caused by an over‐thickened crust later subjected to orogenic collapse, exhumation‐metamorphism, and decompressional melting. This event might have taken place between 1.0 to 0.5 Ga during the Pan‐African Orogenic crustal growth, linked to the amalgamation of Gondwana.

The end of the Neoproterozoic global ice age has promoted the evolution of the Earth's surface system and initiated the ‘Great Explosion of Life’. Glaciation deposits provide valuable insights into the extreme climate conditions. In the southern margin of the North China Craton (NCC), an Ediacaran glacial deposit named ‘Luoquan Formation’ has been recently described in Luonan County, Shaanxi Province. It has significant characteristics of dark grey and black glacial deposits. Through extensive research in sedimentology, geochemistry and geochronology, the glacial sedimentary evolution sequence of the Luoquan Formation has been established. This research also help to define the age of the formation and reveal its provenance and sedimentary environment. The study reveals that four lithofacies associations were identified in the Luoquan Formation: diamictites, carbonates, dropstone‐bearing rock and black shale. The Luoquan Formation has experienced three cycles of glacial advance–retreat. Sedimentological evidence suggests that the sedimentary environments of the Luoquan Formation evolved from subglacial (diamictite) to intertidal, then to intertidal lagoon, or from subglacial deposits to shoreface (inner shelf, subtidal), then to deep water basin and fine‐grained turbidite and ice‐rafting. The age of the Luoquan Formation is estimated to be 562–550 Ma constrained by indirect chronological and paleontological data, maybe representing an Upper Ediacaran glaciation that occurred later than the Gaskiers glaciation. The overall age profile of detrital zircons from the Luoquan Formation can be divided into six groups, ranging from 1.1 to 1.6, 1.85 to 1.95, ~2.1, ~2.3, ~2.5 and 2.65 to 2.9 Ga. These age groups are consistent with the Archean to Meso‐Neoproterozoic magmatic–tectonic events in the southern margin of NCC, indicating they are ascribed to an origination directly from the southern margin of NCC. The Luoquan Formation exhibits the characteristics of isochronous and different sedimentary facies, with the glacial front moving from north to south. The discovery of Luoquan Formation in Lianshuigou section not only reflects the important significance of the restoration and reconstruction of the Ediacaran ice age, paleoenvironment and palaeogeography of the NCC but also provides significant evidence to support the further subdivision and correlation within the Ediacaran glacial deposits globally.
