摘　　要：油页岩型天然碱矿床是中国天然碱矿床重要的成因类型,成矿大地构造背景为活动性构造带,成矿环境为干旱气候条件下的深水盐湖。钠主要源于深部油田的热卤水,碳主要源于剥蚀区碳酸盐岩。成矿作用为混卤化学沉积作用:源于深部油田的富钠热卤水与地表富碳常温卤水混合导致碱矿物析出成矿。找矿方向:南阳次级盆地东端、吴城盆地东南部及构造活动带内的油页岩分布区。The oil shale type of natural soda deposit is an important genetic type of natural soda deposits in China.The metallogenic tectonic setting is an active tectonic belt,and the metallogenic environment is deep water salt lake under arid climate.Sodium mainly comes from the hot brine of deep oil field,and carbon mainly comes from carbonate rock in denudation area.The mineralization is the chemical deposition of mixed brine:the mixture of sodium-rich hot brine from the deep oil field and the surface carbon-rich normal temperature brine results in the precipitation of the soda Minerals.Prospecting Direction:East end of Nanyang Secondary Basin,southeast of Wucheng Basin and distribution area of oil shale in tectonic active zone.
