In order to adopt the best safety procedures, man-made earthquakes should be differentiated as a function of their origin. At least four different types of settings can be recognized in which anthropogenic activities ...

Macro-microscopic tectonic analysis and lithologic features show that the gold-bearing breccia bodies in the Shuangwang gold deposit, for hydrofracturing of the deep-sourced and alkali-rich fluids in the Devonian sodi...
The formations of many mesothermal gold-quartz deposits are closely re1ated with fluid pressure. In the course of ore-forming of gold deposits, fractures act as values, promoting cyclic fluctuations in fIuid pressure ...

The conduit system of heat fluids in diapiric belt of Yinggehai basin is dominantly vertical faults and fractures . Detailed research on the formation mechanism and their occurrence features shows that the faults and ...
Hydrofracturing has been found in a numbr of sedimentary basins throughout the world, which pay an important role in the migration of hydrocarbon and compaction of deposits in overpressured impermeable muddy rock. The...
Hydraulic fracturing occurs in diverse fields of geosciences. We introduce effects of fluid buoyancy into the CGDD (Christianovich-Geertsma-DeKlerk-Daneshy) model of hydranlic fracturing. In the model, a two-dimension...

Since it was used as a stimulating technique of oil or gas wells to raise productivity and recovery ratio in the late 1940s, the hydrofracturing technique has become an extensively adopted method of in-situ stress mea...
