甘肃北山(马宗山)一般泛指天山的东延部分,东部与龙首山相接。北山下寒武统双鹰山组是东疆和甘肃河西主要含P—V—U矿层位。目前已发现矿床(点)多处,为重点找矿对象之一。一、含矿岩系早寒武世双鹰山组P—V—U含矿岩系受东西构造带的控制,呈狭长带状分布于震旦纪古隆起带边缘,甘肃境内西起方山口,东至洗肠井,长达400多公里(图1)。含矿岩系以平行不整合或角度不整合于震旦亚界之上,与上覆中上寒武统西双鹰山组呈整合接触。P—
Gansu Beishan (Ma Zongshan) generally refers to the eastern part of the extension of Tianshan, the eastern phase with the first dragon. The Lower North Cambrian Shuangyashan Formation in Beishan is mainly composed of P-V-U orebodies in eastern Xinjiang and Hexi Gansu. At present, many deposits (spots) have been found, one of the key prospecting targets. First, the ore-bearing rock series The P-V-U ore-bearing series of the Early Cambrian in the Double-eagles in the Early Cambrian were controlled by the East-West tectonism belt and distributed in a long and narrow band on the margin of the Sinian paleo-uplift. In the west of Gansu, To washing colon hole, up to 400 kilometers (Figure 1). The ore-bearing rocks are unconformity or angle unconformity on the Sinian sub-boundary and are in synchronic contact with the overlying Upper-Middle Cambrian Xiyanyingshan Formation. P-
