吐哈盆地西南缘新构造控矿规律及十红滩铀矿床外围成矿有利区预测
Ore-controlling regularities of neotectonic activity at southwestern margin of Turpan-Hami basin and prognosis of metallogenically favorable areas adjacent to Shihongtan uraniuim deposit
【摘要】 本文根据吐哈盆地西南缘新构造运动的表现特征 ,结合已知铀矿床、矿点的空间分布 ,认为该区新构造控矿规律主要体现在 3个方面 :( 1 )由新构造复活基底断裂形成的“断裂挠曲”控矿 ;( 2 )新构造褶皱形成的“坡中坡”转折区域控矿 ;( 3 )新断裂构造形成的地下水局部排泄源也参与了对铀矿化的控制作用。依据这些规律 ,笔者预测十红滩北带之北带仍有成矿远景 ,并认为白咀山西侧及迪哈尔 5 1 1线附近区域具有一定的成矿潜力。
【Abstract】 Based on characteristics of neutectonic activity at the southwestern margin of Turpan?Hami basin,as well as the spatial distribution of known uranium deposits and occurrences,authors of this paper suggest that ore?controlling regularities of neotectonic activity are mainly expressed in three aspects:(1)ores are controlled by "faulting flexture" formed by tectonically rejuvenated basement fault;(2)ores are controlled by the hinge area of the "slope in slope" formed by neotectonic folding;(3)the local discharge area formed by neotectonic faulting of groundwater also plays certain role in controlling uranium mineralization.On the basis of above regularities,authors make a prognosis that the northern zone of northern Shihongtan is of certain metallogenic prospects,in addition,the western Baizuishan and the area near exploration line No.511 of Dihaer area are of certain metallogenic potential.
