Geology, fluid inclusions, isotope geochemistry, and geochronology of the Paishanlou shear zone-hosted Gold Deposit, North China Craton

Ore Geology Reviews, 2005
Abstract The Paishanlou gold deposit lies along the northern margin of North China Craton gold province, the third largest Au province in China. The deposit is mainly hosted in Archean metamorphic rocks of the Jianping Group and is structurally controlled by two sets of ductile shear zones.

Effect of filling material on dynamic response and energy dissipation in sandstone with double weak interlayers

Results in Engineering
With the extension of China's transportation infrastructure into the complex geological areas in the west, the presence of numerous weak interlayers in the geology has posed significant challenges to the construction of tunnel transportation.

Frictional behavior of talc-calcite mixtures [PDF]

, 2015
Faults involving phyllosilicates appear weak when compared to the laboratory-derived strength of most crustal rocks. Among phyllosilicates, talc, with very low friction, is one of the weakest minerals involved in various tectonic settings.

A new uncertainty analysis method based on geostatistical simulation and a case study

Case Studies in Construction Materials
The stability of slopes might be influenced by numerous uncertainty factors. In this study, three uncertainty factors are considered in the slope stability analysis, which are locations of weak structural surfaces, structures of soil-rock mixtures ...
