沉积型层控矿床

沉积型层控矿床

 

全区存在沉积型层控矿床的研究区主要有卡尔卡拉林,吉尔吉斯阿拉套,楚-伊犁,卡拉套地区。

全区沉积型层控矿床地质时代有晚古生代寒武系(Cam),早古生代泥盆系(D),石炭系(C),中生代侏罗系(J),白垩系(K),新生代古近系(E)。

全区沉积型层控矿床矿物组合有三水铝矿,赤铁矿,高岭石,磁铁矿,钒云母,石英,磷灰石,硬水铝石,沥青铀矿,铀石,矾土。

全区围岩蚀变类型有硅化作用,绢云母化,绿帘石化,氧化。

主要矿物元素有Al,V,Fe,phosphorite。

次要矿物元素有Mo,U,Ni,Zn。

全区矿床规模以小型矿床为主,中、大、超大型矿床偏少。

全区沉积型层控矿床类型主要有沉积型层控——铝矿床、铁矿床、磷矿床、铀矿床、钒矿床。

以下为该类矿床的详细分类。
