Title: Evolutionary features of Caledonian magmatic rock and its relationship to uranium mineralization in the northern Danfeng area
Abstract:Caledonian magmatism in northern Danfeng area has experienced three tectonic stages as compression,transition and tension and formed granite batholith,granite stock and granitic pegmatite vein respect...Caledonian magmatism in northern Danfeng area has experienced three tectonic stages as compression,transition and tension and formed granite batholith,granite stock and granitic pegmatite vein respectively.These rocks are obvious different in mineral component,texture and structure.Movement direction of magma is from north to south and from east to west with oblique uplifting.The transportation of magma is synchronous to the differential crystallization,diagenesis and ore-forming of uranium mineralization.The mineralization is located in biotitic granitic pegmatite veins which is formed in the final tension stage.This uranium forming mechanism can well explain the phenomenon that the deposit,occurrence,mineralizing occurrence found at present mainly distribute in the biotite granitic pegmatite veins between the contact zone of granite stock and southern granite batholith,and can be used as the criteria to select target for uranium prospecting in the area.Read More
