Other Abstract

The Ludong region of eastern Junggar evolved as a relatively independent accretionary basin with larger volcanic rocks filling through the Carboniferous. During the late Early Carboniferous, Ludong region evolved in the set of post-collision stress relaxation period and developed regional volcanic reservoirs known as Batamayineishan Formation(Bashan Formation). The core and outcrop observations, geochemical and geophysical recognition indicate that the Bashan Formation in Ludong region is a set of defective potassium and rich sodium alkaline-sub alkaline volcanic rocks. There are five volcanic eruption cycles recognized in the Bashan Formation. With the tectonically relaxation, the volcanic activity in each cycle gradually weakens and forms various volcanic facies combinations in different areas. The distribution of volcanic faces is controlled by volcanic apparatus topography, and the andesite-basalts are developed in the western of the main volcanic edifice, while the eastern volcanic centers have erupted explosive volcanic breccia and overflow phase basalt or rhyolite. The interval between volcanic eruptions in Bashan Formation are conducive to development of local source rocks and volcanic weathering crust, which provides the necessary sources and reservoirs for the Carboniferous "self-generation and self-bearing" hydrocarbon accumulation of Ludong region.
