摘　　要：通过利用综合物探方法寻找和勘查许昌泉店大型沉积变质矿床实例的研究，认为航、地磁异常重合是一个找矿的前提；高磁测量解释为薄板状体者对应单层矿，多层叠加板状体者对应多层矿；模型体与主矿体在位置、层数、规模、产状存在较好的对应关系，而与其他小矿体在位置上有偏移，其模型体往往在矿体的下方；矿体与矿化体上均有二次导数异常。Quandian large sedimentary metamorphic ore deposit was found by using comprehensive geophysical methods. after researching the exploration of the deposit, we conclude that aeromagnetic and geomagnetic anomalies are precondition for prospecting;high magnetic survey shows that laminated plate is single layer ore, and multilayer superposition plate is multi-layer ore;model body and the main ore bodies have a good corresponding relationship on their position, layer number, scale and occurrence, while the other small ore bodies are different in position, whose models are often found in the bottom of the ore body;both the ore bodies and mineralized bodies contain the second derivative anomaly.
