Late Triassic sinistral shear in the East Gobi Fault Zone, -- &#; The East Gobi Fault Zone (EGFZ) is a structural corridor in southeastern Mongolia ().Areas within and adjacent to the EGFZ are well known for abundant mineral resources (e.g. the Oyu Tolgoi porphyry Cu–Au–(Mo) deposit; Perello et al., ).Despite being a region rich in mineral resources, tectonic models are largely speculative due the dearth of published studies

What is the difference between a parallel arc fault and a -- &#; If the damaged wires are close enough together, an arc may occur between the exposed wires. Because a parallel arc occurs between conductors at different voltages, the amount of current can vary widely, from very little to a very high amount (up to the short circuit current available for that circuit). A series arc occurs when electricity
