Fractures have significantly impacted the preservation, enrichment, and productivity of shale gas in Longmaxi Formation complex structural area southern Sichuan Basin. Based on outcrop, core, imaging logging, inclusion analysis, acoustic emission experiments, burial thermal evolution history data, formation stage, preservation conditions fractures were comprehensively studied. Shear are main fe...

OBJECTIVE To determine the features of earthquake-related pelvic crush fractures versus non-earthquake fractures with digital radiography and multidetector row computed tomography. METHODS One hundred and sixty-seven survivors with pelvic crush fractures in the 2008 Sichuan earthquake were entered in our study as the earthquake-related group (139 underwent digital radiography, 28 underwent mu...

The paper presents the results of an analysis faults different ranks near Okhotnichya Cave in Pribaikalye, aimed at identifying their role formation and evolution cave its adjacent areas. This was done using rank-wise structural-paragenetic faults, which forms basis a specialized mapping tool for fault zones. Factual evidence obtained through several methods. speleoinitiating fracture network s...

Background: Conventional fixation methods of posterior wall acetabular fractures feature the use of plating and lagscrews. However, fixation of posterior wall fractures with buttress plating alone offers potential advantages by avoidingthe hardware complications related to hardware placement through the wall fragment. The purpose of this study wasto examine if buttress plating...

Shear failure is the dominant mode of earthquake-causing rock failure along faults. High fluid pressure can also potentially induce rock failure by opening cavities and cracks, but an active example of this process has not been directly observed in a fault zone. Using borehole array data collected along the low-stress Chelungpu fault zone, Taiwan, we observed several small seismic events (I-typ...

evidence acquisition a search of pubmed for studies on proximal fifth metatarsal fracture and jones fracture focusing on the classification and management was performed. the reference list of the retrieved articles was searched for additional related studies. conclusions lawrence and botte’s classification of proximal fifth metatarsal fractures is recommended by experts, due to its implication ...

Abstract The microseism induced by hydraulic fracturing is of great significance to the development geothermal reservoirs and site selection systems. In this study, taking field data from Qiabuqia as a geological reference, several models are developed for simulations based on included in commercial FracMan™ software suit. A series numerical carried out explore effects different fracture parame...

Abstract. We collected drone data to quantify the kinematics at extensional fractures and normal faults, integrated this information with seismological reconstruct stress field, critically compared results previous fieldwork assess best practice. As a key site, we analyzed sector of northeast rift Mt Etna, an area affected by continuous ground deformation linked gravity sliding volcano's easter...
