摘　　要：A significant phase of global warming appeared during the Llandovery and productive Silurian hot shale was preserved all over the world.The lower Silurian shale is the main effective source rock for most of the Paleozoic hydrocarbon in Iran and the Arabian platform.Silurian hot shales have become prospective resources for new energy such as shale gas.The regional distribution and shale gas potential of the lower Silurian hot shale in southern Iran and the Arabian plate are determined using outcrops and exploration well samples data from previous studies.The studied area has a high organic content(on average more than 2%),maximum burial depth is 5300 m,shale thickness of 30-200 m,organic matter maturities(most comparable),clay minerals content ranging from 20%to 57%,quartz content ranges from 20%to 49%,feldspar content ranges from 10%to 15%and calcite content ranges from 1.48%to 5%which all favor shale gas generation and accumulation.We concluded that southern Iran and east-central Saudi Arabia are two of the most sustainable and favorable locations for shale gas exploration and production for lower Silurian hot shale after assessing all of the key characteristics.
