“…At the scale of the whole massif, we argue that they are nearly coeval and result from the same deformation mechanism. Such deformation features are widely developed in the Mesozoic extensional domes in eastern China, representing gravitational décollement and layer-parallel slip coeval with the doming (Faure et al, 1996, Faure et al, 1998, Faure et al, 2003, Lin et al, 2000and Lin et al, 2013.…”

As the oldest exposed basement and the typical sedimentary cover of the Yangtze craton, the Huangling massif is a suitable place to decipher the tectonics of South China block. Structural analysis shows that the Huangling massif has an elliptic domal shape with N-S striking long axis, an asymmetric antiform with a steep western flank and a gentle eastern flank. There, three litho-tectonic units are recognized, from inner to outer parts: (1) ArcheanPaleoproterozoic metamorphic rocks intruded by Neoproterozoic granitoids; (2) Neoproterozoic to Jurassic sedimentary envelope around the dome core; (3) Cretaceous terrigeneous alluvial-fluvial deposits, unconformably overlying the dome flanks. Coeval with the uplifting of the massif, the pre-Cretaceous strata on the western and eastern flanks of the Huangling massif were involved in a series of folds with nearly N-S axes and layer-parallel slip structures with top-to-the-W and top-to-the-E motion, respectively. The subsequent brittle normal faulting controlled the deposition of the graben or half-graben basins on both flanks. Cooling history reveals that the Huangling massif underwent uplifting between 160 Ma and 110 Ma with an average cooling rate of 2-3 °C/Ma. Moreover, the Huangling area was not significantly affected by the Early Paleozoic and Triassic orogenies of South China. Comparable with the contemporaneous extensional structures, such as metamorphic core complexs, syntectonic plutons bounded by ductile normal faults, and rift-related basins in eastern China, it is proposed that the Huangling massif, might be an extensional structure controlled by a weak crustal extension. In this case, it will represent the western front of the Late Mesozoic lithospheric thinning in entire eastern China. However the compressional model cannot be ruled out.

The South China Block (SCB) experienced a polyphase reworking by the Phanerozoic tectonothermal events. To better understand its Late Mesozoic tectonics, an integrated multidisciplinary investigation has been conducted on the Dayunshan–Mufushan composite batholith in the north‐central SCB. This batholith consists of two major intrusions that recorded distinct emplacement features. According to our structural analysis, two deformation events in relation to batholith emplacement and subsequent exhumation are identified. The early one (D1) was observed mostly at the southern border of the batholith, characterized by a top‐to‐the‐SW ductile shearing in the early‐stage intrusion and along its contact zone. This deformation, chiefly associated with the pluton emplacement at ca. 150 Ma, was probably assisted by farfield compression from the northern Yangtze foreland belt. The second but main event (D2) involved two phases: (1) ductile shearing (D2a) prominently expressed along the Dayunshan detachment fault at the western border of the batholith where the syntectonic late‐stage intrusion and minor metasedimentary basement in the footwall suffered mylonitization with top‐to‐the‐NW kinematics; and (2) subsequent brittle faulting (D2b) further exhumed the entire batholith that behaved as rift shoulder with half‐graben basins developed on its both sides. Geochronological constraints show that the crustal ductile extension occurred during 132–95 Ma. Such a Cretaceous NW–SE extensional tectonic regime, as indicated by the D2 event, has been recognized in a vast area of East Asia. This tectonism was responsible not only for the destruction of the North China craton but also for the formation of the so‐called “southeast China basin and range tectonics.”

The Late Mesozoic magmatic province is a prominent feature of the South China Block (SCB). However, the tectonic regimes associated with the magmatism are still elusive. A combined anisotropy of magnetic susceptibility and gravity study has been carried out to determine the fabric patterns and shape at depth of the Dayunshan‐Mufushan composite batholith in the north‐central SCB. This is a companion paper to Part 1 that presented the structural and geochronological data of this batholith. The magnetic fabrics in the batholith interior predominantly reflect magma flow structures. Two distinct patterns of the magnetic lineations are defined, around NNE‐SSW and WNW‐ESE trends for the early‐stage and late‐stage intrusions of the batholith, respectively. The gravity survey reveals that the early‐stage intrusion has a main feeder zone located below its northern part, while several linear feeder zones trending NNE‐SSW are inferred for the late‐stage intrusion. Integrating all results, a two‐stage construction of the batholith with distinct tectonic regimes has been established. It is concluded that the early‐stage intrusion experienced a southward magma transport during its emplacement, partially assisted by far‐field compression from the north at ca. 150 Ma. Conversely, the emplacement and exhumation of the late‐stage intrusion was accommodated by a NW‐SE crustal stretching involving a lateral magma expansion above the multiple feeder zones (likely corresponding to extensional fractures) and ductile shearing during 132–95 Ma localized mainly along the Dayunshan detachment fault. Finally, we discuss the geodynamic linkage between the paleo‐Pacific subduction and the Late Mesozoic tectonomagmatism in the SCB.
