| 中文摘要: |
| 南岭构造带东段自震旦纪以来经历了四次“开合”演化旋回:早震旦世—志留纪“开合”旋回,形成了以震旦系和寒武系为代表的基底铀源层;中泥盆世—三叠纪的“开合”旋回,造就了二叠系铀源层及印支期铀源体;侏罗纪的“开合”旋回,再造了燕山期的富铀源体;白垩纪—第三纪的“开合”旋回,提供了铀成矿热液和成矿空间,促使铀聚集成矿,形成独具特色的南岭铀成矿带。 |
| 英文摘要: |
| The eastern part of Nanling tectonic zone has exposed to ‘Opening’ and ‘Closing’ evolutional cycle for four times ever since Sinian Period.They are (with a chrono-logical order) :the‘Opening’and‘Closing’cycle of Early Sinian Epoch—Silurian Period, which forms the base uranium source layer of Sinian System and Cambrian System;the ‘Opening’ and‘Closing’ cycle of Middle Devonian Epoch—Triassic Period,which forms the Permian uranium source layer and the Indo—Sinian Period uranium source granite;On the basis of the above two processes,the‘Opening’and‘Closing’cycle of Jurassic Period built the uranium enriched source granite;whereas the‘Opening’ and‘Closing’ cycle of Creta-ceous Period—Tertiary Period,facilitate the mineralization of uranium by providing abundant minerogenic hydrothermam fluid well as space.Thus the distinguished Nanling Ore-bearing Zone came into being. |
