As the western boundary fault of the Songliao Basin and the eastern margin of the Da Xing' an Mountains, Nenjiang-Balihan Fault Belt is located in the central part of northeastern China, the eastern segment of the Central Asian Orogenic Belt It extends along the boundary between the Heilongjiang and Jilin provinces, and the Inner Mongolia Autonomous Region, with the NNE striking, and then goes into the Hebei Province to the south, connecting with the Pingchang-Sangyuan Fault, with a total length over 1200km. The Nenjiang-Balihan Fault Belt is considered traditionally to be a huge deep-seated fault, and characterized by a normal fault or detachment fault. So far, some regional geophysical research on this fault zone is focused on its northern segment, the Nenjiang Fault, including the bouguer gravity anomaly, the aeromagnetic anomaly, and the deep reflection seismic profile, which revealed the regional distribution of the Nenjiang Fault System and indicated that Nenjiang Fault System should be a huge low-angle normal fault or detachment fault. In the southern segment of this fault belt, it is called the Hongshan-Balihan Fault, which has been studied as the eastern margin detachment fault of the Kalaqin (Harkin) Uplift. The study on the middle part of the Nenjiang-Balihan Fault Belt is rare. We newly found a S-L typed ductile shear zone at the Lingxia, Baicheng City, the middle-southern part of the Nenjiang-Balihan Fault belt, and compared this ductile shear zone with that at the Louzidian area, in the southern part of the Nenjiang-Balihan Fault belt. Based on the field investigation, measurements of structures in the field, micro-structural studies, finite strain measurements, a study on preferred crystal orientations of quartz determined by Electron Back Scatter Diffraction and muscovite Ar-40/Ar-39 chronology of the deformed rocks in the ductile shear zone, we suggested that the deformation features of the Lingxia and Louzidian ductile shear zones are similar, and that they represent one continuous fault, i.e., the middle-southern segment of the Nenjiang-Balihan Fault Belt, which experienced a sinistral strike-slip ductile shearing in the Early Cretaceous (similar to 130Ma). In this study, we found a ductile shear zone at the Nierji area, in the northern-middle section of the Nenjiang-Balihan Fault Belt. By the measurement of structural elements, the micro-structure studies and the finite strain measurement, the Nierji ductile shear zone shows similar NE striking and sinistral strike-slipping shearing to that from the Lingxia and Louzidian ductile shear zones, but presents L-typed extensional shearing which is different from the S-L typed shearing in the Lingxia and Louzidian areas. The zircon U-Pb dating on the granitic L type tectonite at the Nierji area shows that; 1) all zircons have a high value of Th/U (0. 06 similar to 1. 25) and exhibit euhedral crystal shapes and an oscillatory zoning in CL images, indicating their magmatic origin; 2) these zircon ages are divided into two ranges, 258 similar to 403 Ma (n = 5) and 207 similar to 174Ma (n = 15, with a mean value of 190. 0 +/- 6.1Ma); 3) the old age group of 258 similar to 403Ma generally displays a core-rim texture in CL images, indicating multiple Paleozoic magmatic events having been in this area, and the two core ages of similar to 190Ma was found in the young age group of 207 similar to 174Ma, suggesting that this area underwent a stronger Early Jurassic magmatic intrusion event and the protolith of Nierji shearing zone formed in the early Middle Jurassic (similar to 170Ma), not the previous Permian. The laser Ar-40/Ar-39 muscovite dating shows a relatively well plateau age of 158. 99 +/- 0. 61 Ma. The micro-structural observation, the rotated K-feldspar porphyroclasts and S-C fabrics demonstrate the sinistral shear sense of the ductile shear zones, and the recrystallization types of feldspar show bugling recrystallization (BLG) and the recrystallization types of quartz display a transition stage of subgrain rotation to grain boundary migration recrystallization (SR-GBM). Therefore, we suggest that the metamorphic grade of the shear zone in the Nierji shearing zone should have reached high greenschist facies conditions and deformation temperatures of around 500 degrees C, which is obviously higher than the blocking temperature of muscovite (300 similar to 400 degrees C). Hence, the Ar-40/Ar-39 age of muscovite from the Nierji shearing zone should be a cooling age. We think that the sinistral strike-slipping event at the Nierji area occurred in the Middle to Late Jurassic and the Nierji shear zone underwent fast uplifting at 158. 99 +/- 0. 61 Ma. Combined with the newly published chronological data from the Heilongjiang blueschists (have been called as Helongjiang Group) in NE China and the famous Tancheng-Lujiang Fault Belt and its northern extension in the East China, and the study on the speed and direction of movement of the West Pacific Plate, we suggest that; 1) the Nenjiang-Balihan Fault Belt maybe undergo three main deformation stages, including the Middle to Late Jurassic sinistral extensional strike-slip shearing stage (similar to 160Ma), the middle Early Cretaceous sinistral strike-slip or oblique slip shearing stage (similar to 130Ma) and the late Early Cretaceous extensional stage; 2) these two strike-slip shearing stages are similar to those from the Tancheng-Lujiang Fault Belt and its northern extension (Dunhua-Mishan and Jiamusi-Yitong Fault Belts), and the formation time of the early shearing (similar to 160Ma) is later 10Myr than the time of subduction (similar to 170Ma) between the Jiamusi and Songliao Blocks; 3) the early formation stage of the Songliao Basin was controlled by the Middle to Late Jurassic sinistral strike-slip fault, which are related to the speed and direction of oblique subduction of the West Pacific plate under Eurasian continent and responsive collision during the Jurassic times.
