摘要
汝阳东沟钼矿为新近探明的一特大型斑岩钼矿床。燕山期花岗斑岩体向北东方向呈舌状隐伏于下铺一带,倾向南东,为高硅、富钾、低镁铝的浅成侵入岩。下铺花岗斑岩体是成矿的主导因素,其形态、产状特征控制了矿体形态、产状、厚度及品位的变化。这一发现为外围钼矿勘查提供了依据。
Ruyang Donggou molybdenum ore deposit is a newly found oversize porphyry type molybdenum deposit.Yanshanian period shallow granite-porphyry mass intruded under the Xiapu area which inclines in NE direction with high silicon,rich potassium,low magnalium and hypabyssal elements.Xiapu granite-porphyry mass is metallogenic dominant factor,its shape and occurrence characteristics control the ore body＇s shape,occurrence,thickness and ore grade change.
