Abstract:

     We are applying to petroeum geoscience, the theory of a Triassic hypervelocity impact crater forming the Songalio Basin, northeastern China by Buthman ( 2023) as evidenced by satellite gravity exhibiting clear circular geometries, with radial wheel and spoke like geometries; and E-2 magnetics show simple high-susceptibility. The magnetics exhibit a 90 km transient crater, a 185 km inner ring, with calculated instantaneous energy of 3.62 times ten to the 23rd joules induced into the Earth at impact.  

 Thin continental crust together with the lithosphere behave as a rigid plate which float on and deform the underlying plastic asthenosphere. Upon impact the asthenosphere oscillates above the upper mantle. The elastic effects behave as a ripple in a pond. The multiple rings in large impact basins are the ripple effects of the sine wave The purpose of his presentation is to apply a model of ring propagation, Y=sin(x)/ x in predicting an anticline associated with the Daquing  supergiant oil field ( 21.9 BBLO)  located in the Songalio Basin in northeastern China ,defined from center point to outer rim, and using the square root of 2 spacing equation developed from observations of impact craters of Mercury and the Earth’s Moon.   A more detailed application of the aforementioned ring prediction  is described in detail in Impact Crater Tectonics  by Buthman 2023

 The Songalio impact basin spacing calculations yield a 185km diameter 2^nd anticline deformation penetration in the lithosphere . Impact structural deformation of extensional forces paired with tectonic subduction and rifting resulted in nonmarine depositional environments from the Mesozoic  .

 The Daquing oil field, located at the 354 km. diameter, is intensely faulted and folded with thinned crust Hydrocarbon lacustrine source rocks were deposited 92 MYA ( Upper Cretaceous ) and  thermally matured at relatively shallow burial depth of  2-3 km. due to the high geothermal gradient and expelled  hydrocarbons 65 MYA ( Upper Cretaceous) ,  filling fluvial and deltaic feldspathic and graywacke sandstones in structural traps ( Wanli, 1985)

In addition , volcanics  located at the 875km. diameter derived from reservoirs formed by impact effects of crustal and upper mantle reflected and rarefaction shock waves leading to tensile failure and magmatism resulting  in the mantle bulge and high heat flow critical in  the hydrocarbon maturation , timing, and expulsion.
