Tectonic System & Structural Geology
Late Paleozoic-Mesozoic structural style, deformation sequence, and formation process and mechanism of the checkboard structure in the eastern Junggar Basin
REN Xincheng, XIU Jinlei, LIU Lin, LIU Dezhi, TAN Xingyu, ZHANG Beihang
2023, 29(2): 155-173. doi: 10.12090/j.issn.1006-6616.2022113
Abstract (1438) HTML (513) PDF (48193KB)(146)
Abstract:

The eastern Junggar has experienced multistage intra-continental deformations since the late Paleozoic. The checkerboard structure is one of the most notable features of the Junggar Basin, especially the eastern Junggar Basin, and its formation and evolution is a microcosm of the intracontinental de...

Abstract (883) HTML (277) PDF (34952KB)(51)
Abstract:

The sedimentary lithology is complex in the middle sub-member of the first member of the Liushagang Formation(L1-M) of the Weizhou-11A oilfield in the southwest Weizhou depression of the Beibu Gulf Basin. The reservoir changes rapidly in both vertical and horizontal directions, and the distribution ...

Geo-hazards & Engineering Geology
Evaluation of landslide susceptibility in the gentle hill-valley areas based on the interpretable random forest-recursive feature elimination model

2023, 29(2): 202-219. doi: 10.12090/j.issn.1006-6616.2022128
Abstract (867) HTML (189) PDF (42802KB)(85)
Abstract:

This study aims to evaluate landslide susceptibility and explain the internal mechanism of gentle hill-valley through SHAP partial interpretation and PDP partial dependency map based on the random forest-recursive feature elimination model to provide references for geological disaster prevention and...

Study on fault-slip potential induced by water injection in the deep thermal reservoir of the Gaoyang low uplift, Hebei Province
ZHU Siyu, CAO Jiawen, FENG Chengjun, WANG Jiming, MENG Jing, QI Bangshen, ZHANG Peng
2023, 29(2): 220-235. doi: 10.12090/j.issn.1006-6616.2022093
Abstract (567) HTML (162) PDF (22377KB)(46)
Abstract:

Recently, water injection-induced earthquakes caused by faulting instability have become a prominent geological safety issue for safely exploiting deep geothermal resources. This study investigates whether the future large-scale development of deep geothermal resources in the Gaoyang uplift will des...

Characteristics and slope structure of the Beishan landslide group in Tianshui City
WANG Haojie, SUN Ping, ZHANG Shuai, WANG Tao, REN Jian
2023, 29(2): 236-252. doi: 10.12090/j.issn.1006-6616.2022052
Abstract (1068) HTML (429) PDF (77929KB)(124)
Abstract:

The Beishan area in Tianshui City is located in the transition zone between the mountainous area on the northern edge of the Qinling Mountains and the Loess Plateau. The solid internal and external dynamic coupling has induced large landslide groups with a zonal distribution, which seriously restric...

Factors inducing the Xigouwan landslide in the Three Gorges Reservoir area and the influence of antecedent precipitation
SHI Xuelei, HAN Xudong, YANG Xiuyuan, SUN Xiujuan, LI Yanyan
2023, 29(2): 253-263. doi: 10.12090/j.issn.1006-6616.2022049
Abstract (679) HTML (178) PDF (14053KB)(125)
Abstract:

Monitoring data over the years have shown that seasonal rainfall and reservoir level changes have always accompanied the accelerated deformation of the Xigouwan landslide, which makes it difficult to identify the dominant triggering factors of landslide deformation and poses a challenge to risk anal...

The advantage of the nonlinear mixed model and its application in typical seismically active areas in China
ZHOU Hanyang, DU Jianjun, ZHANG Shuting
