摘　　要：岩浆热液活动对成矿普遍具有直接或间接的影响,"岩浆岩"作为三大要素之一为地质工作者所重视。吉林省通化地区岩浆活动强烈,形成了一系列岩基(岩体)、岩株(小岩体)和中酸性岩脉,以往地质工作者重视大岩体成矿,小岩体在区域地质和矿产勘查工作中往往不被重视。以通化南部苇沙河岩体群为例,利用汤中立院士"小岩体成大矿"的理论,结合该区地球物理、地球化学等特征,认为苇沙河岩体符合"小"和"广"的找矿规律,具备寻找到铜、金、钼多金属矿床的潜力。Magmatic hydrothermal activity has a direct or indirect effect to mineralization. As one of the three major elements,"magmatic rocks" has been attached great importance by geologists. In recent years, the intense magmatic activity in tonghua area of Jilin province forms a series of batholithes (magmatic rocks), stocks (small intrusion bodies) and intermediate-acid dikes. In the past, geologists paid attention to the mineralization of large magmatic rocks in regional geology and mineral exploration, while small intrusion bodies is often ignored. Taking the Weishahe intrusion group as an example, using the theory of "small intrusive bodies forming large deposits" put forward by Academician Tang Zhongli, combining the characteristics of geophysics and geochemistry, it can conclude that it has the prospecting potential to find copper- gold-molybdenum polymetallic deposits for the rule of "small" and "extensive".
