河南省地勘二院新发现的内蒙古兴和县曹四夭钼矿是一个超大型斑岩型矿床，目前圈定钼矿体分布面积2.22 km2，东西长1994 m，南北宽1612 m，平均厚度508 m，共估算（333）钼矿石量225万吨，钼金属资源量175万吨，平均品位0.078%。对该钼矿体元素分带特征的研究结果显示：1）元素围绕钼矿体呈规律环状分带现象；2）从中心向外围由高温元素到中低温元素呈依次展布的各自独立的地球化学异常分带；3）围绕钼矿体有高中低温矿产分带规律，应注重对成钼作用同期形成的铅锌金等多金属矿产的找寻；4）标型元素比值可以有效圈定钼矿体边界及指示岩浆运移通道；5）矿体主要产出于燕山期少斑花岗斑岩外接触带，构造-岩浆岩带是钼矿床产出的有利场所；6）大同-尚义北东向构造-岩浆岩带相关联的小岩枝上侵部位是寻找类似矿床的重要找矿方向。

The Caosiyao molybdenum deposit found by the No.2 geological prospecting institute of Henan prov-ince in Xinghe County, is a supermassive porphyry molybdenum deposit, and it is the first super-huge type of mo-lybdenum deposit in Inner Mongolia. The distribution area of molybdenum ore has been delimited with a total ar-ea of 22.2 km2, 1994 meters long from east to west, 1612 meters wide in south-north direction, and 508 meters in average thickness. Ore reserves are estimated with 2.25 million tons, molybdenum resource 1.75 million tons and average grade 0.078%. Among them, the industrial ore (333) is 1.38 million tons, and the metal reserve is 1.4 mil-lion tons, the average grade reaches to 0.102%. Based on the research of the molybdenum ore body element zona-tion, we can reveal the following characteristics of the molybdenum deposit: 1) Elements around the molybde-num ore body presents a regular ring zone phenomenon. 2) From the center to the periphery, the geochemical anomaly elememt zone is from high temperature elements to low temperature elements in turn distribution inde-pendently. 3) We should pay more attention to the search of the lead-zinc-gold polymetallic mineral in the same period with the formation of molybdenum deposit. 4) The ratio of the typical elements can effectively determine the boundary of the molybdenum, and it can also indicate the migration pathway of the magma. 5) The ore is mainly develops in the external contact zone with the granite porphyry in Yanshan period. At the edge of the geo-synclinal zone,the structure-magmatic belts is the favorable place for generating the molybdenum ore. 6) The in-vasion sites of apophyses, which associated with magmatic belt of the Datong-Shangyi NE structure-magmatic belt, are favorable places for searching the similar minerals.
