Bedrock geology of DFDP-2B, central Alpine Fault, New Zealand [PDF]

New Zealand Journal of Geology and Geophysics, 2017
During the second phase of the Alpine Fault, Deep Fault Drilling Project (DFDP) in the Whataroa River, South Westland, New Zealand, bedrock was encountered in the DFDP-2B borehole from 238.5–893.2 m Measured Depth (MD). Continuous sampling and meso- to microscale characterisation of whole rock cuttings established that, in sequence, the borehole ...

Adverse Geology Identification Through Mineral Anomaly Analysis During Tunneling: Methodology and Case Study

Engineering, 2023
Accurate and effective identification of adverse geology is crucial for safe and efficient tunnel construction. Current methods of identifying adverse geology depend on the experience of geologists and are prone to misjudgment and omissions.

Laboratory Research on Fracture-Supported Shielding Temporary Plugging Drill-In Fluid for Fractured and Fracture-Pore Type Reservoirs

Journal of Chemistry, 2017
Based on fractures stress sensitivity, this paper experimentally studies fracture-supported shielding temporary plugging drill-in fluid (FSDIF) in order to protect fractured and fracture-pore type formation. Experimental results show the FSDIF was better

Earthquake geology of the Mondy fault (SW Baikal Rift, Siberia)

Journal of Asian Earth Sciences, 2023
The Mondy Fault is a 90 km long E-W trending active structure belonging to the southwestern part of the Baikal rift system, connecting the Tunka depression to the East to the Hovsgol rift to the West. The fault is well expressed in the morphology and formed during the Neogene within a transtensional strain regime (left-lateral + normal ...

Geology of the southern Mesa Central of Mexico: recording the beginning of a polymodal fault system [PDF]

Journal of Maps, 2020
The Mesa Central (MC) of Mexico presents a noticeable feature as is the three-dimensional (3D) deformation of Cenozoic volcanic rocks. To figure out when this unusual deformation began, we constructed a geological map at 1:100,000 scale, with detailed stratigraphy, and thirteen new U-Pb ages in the southern MC.
