Neogene differential structural inversion and hydrocarbon accumulation in the Yitong Basin, NE China

Hydrocarbon accumulation in the northwest Chaluhe Fault Depression, Yitong Basin, North China

“…Many structural traps developed in this belt. Meanwhile, the sedimentary and subsidence centres of the Yitong Basin were closed to this side, and many sand bodies of alluvial fans and near-shore subaqueous fans were developed along this margin (Tang et al 2013). Thus, the northwestern margin played a significant constructive role in the accumulation of hydrocarbons, as has been demonstrated by the successful discoveries of the Yi 59, Chang 43 and Chang 48 wells.…”

Lithology and U–Pb Geochronology of Basement of Cenozoic Yitong Basin in Northeastern China: Implication for Basin Architecture and New Horizon of Deep Natural Gas Exploration

“…The Yitong Basin (YB), which is located in northeastern China and distributed within a long, narrow region trending toward the northeast direction at 45-55 • , is approximately 140 km long and 5-20 km wide and spans a total area of 2400 km 2 [9]. This basin contains three tectonic units: The Chaluhe Fault Depression (CFD), Luxiang fault depression (LFD), and Moliqing fault depression (MFD) ( Figure 1).…”
