摘　　要：吉林省桦甸市大楞场钾长石矿位于吉林省桦甸市老金厂镇。笔者负责该区的详查工作,熟悉掌握了该区的地质资料,区内发现三条工业用钾长石矿体,作者通过实际工作体会,总结了大楞场钾长石矿的地质特征、矿石特点、矿化规律,初步确定了找矿标志。认为在钾长花岗岩顶部细粒相带分布地区、形成该类岩石内接触带附近,伟晶岩往往较发育,易形成钾长石矿床。The Dalengchang potash feldspar mine is located in Laojinchang Town, Huadian City of Jilin Province. Through detailed investigation and familiarization with the geological data of the area, three industrial potash feldspar ore bodies were found. Summarized the geological characteristics, ore characteristics, and mineralization laws of the Dalengchang potash feldspar mine, preliminarily determined the indicator for deposit. Pegmatites tend to be more developed and potash feldspar deposit is easy to form on the top of the Moyite, in the fine-grained zone distribution area and the inner contact zone of the rock type.
