Natural gas hydrates in the Qinghai-Tibet Plateau: Characteristics, formation, and evolution
ABSTRACT: The Qinghai-Tibet Plateau (also referred to as the Plateau) is the largest area bearing alpine permafrost region in the world and thus is endowed with great formation conditions and prospecting potential of natural gas hydrates (NGH). Up to now, one NGH accumulation, two inferred NGH accum...
