近年来，随着人们对矿产理念及预测方式的改变，对现有资料及已知成型矿床的利用愈加现实，具体表现在通过对成矿模式所包含的各种参数标志的发掘及其相互关联的判定，达到直接或间接找寻目标物的目的。本文以栗木矿田成矿概念模式为依据，利用前人观测的原始资料，着重考查了隐伏岩体近程接触带及岩浆岩分异演化系列垂直分带的磁性特征，试图建立地质―地球物理(磁性)模型，为今后将物探方法更好地应用于地质找矿领域做必要的尝试。
近年來，隨著人們對礦產理唸及預測方式的改變，對現有資料及已知成型礦床的利用愈加現實，具體錶現在通過對成礦模式所包含的各種參數標誌的髮掘及其相互關聯的判定，達到直接或間接找尋目標物的目的。本文以慄木礦田成礦概唸模式為依據，利用前人觀測的原始資料，著重攷查瞭隱伏巖體近程接觸帶及巖漿巖分異縯化繫列垂直分帶的磁性特徵，試圖建立地質―地毬物理(磁性)模型，為今後將物探方法更好地應用于地質找礦領域做必要的嘗試。

With a transition of mineral resource ideology and forecasting method,the application of existed da-ta and known deposits becomes more realistic,which is well exemplified by the digging and discriminating of various parameter clues contained in the metallogenic model,and thus the objective of finding the subjects is obtained directly or indirectly.This paper focused on conceptual metallogenic model of Limu ore field and used first-hand observation data of predecessors,and it intensively investigated on the magnetic characteris-tics of both contact near concealed rock body and vertical zoning of magmatite differentiation while it also was trying to build a geological-geophysical (magnetic)model for the purpose of a better application of geophysi-cal methods in future prospecting works.
