Characteristics of Source Rock of Shemshak Formation and Hydrocarbon Accumulation in Kashan Block, Iran

Abstract

Abstract: The Kashan block is a Precambrian metamorphic-based basin of Mesozoic and Cenozoic. Its source rock of Shemshak formation of Middle-Lower Jurassic on outcrop area is assured to be effective source rock by geochemical analysis of the abundance, type and maturity of organic matter, integrated with oil source correlation. The element evolvement for petroleum accumulation indicates that the region-al geological setting in this study area contributes to the formation and evolution of oil-gas reservoir. It is concluded that there exist both Tertiary reservoirs with source rock of Shemshak formation and primary reservoirs of it in Kashan block.

Key words: Iran, Qom basin, source rock, Shemshak fonnation, tectonic movement, burial history, hydrocarbon-generating history
