最近我們在閩北南平县大历口王源村周围找到数处蛇紋岩体。在0.4平方里的范围內共发現三处,长度分别为200米,200米,500米;寬为100米;150米;200米。本区蛇紋岩显深黑綠色,偏光鏡下鑑定結果,纤維蛇紋石及叶蛇紋石占90％以上,具网状結构,网脉由蛇紋石和粉末状磁铁矿組成,网脉間分布着蛇紋石之隐晶貭变种——胶蛇紋石。40个样品化驗結果,MgO一般占38—42％。另外从有关单位踏勘資料証明,建阳县崇雒北历村附近也有超基性岩体,并驗証了該地航测磁异常系因此而成。經福建省地貭局实驗室鑑定为蛇紋岩。浦城县九牧西瓜坪也发現輝石橄欖岩,它們呈小岩株状侵入于前震旦紀片岩系中。上述三个岩体恰好位于經航測所証实的
Recently, we found several serpentinite bodies around Wangyuan Village, Dalikou, Nanping County, northern Fujian. Within 0.4 square meters were found in a total of three, length of 200 meters, 200 meters, 500 meters; width of 100 meters; 150 meters; 200 meters. The serpentinite in this area is dark greenish green. The identification results under polarizer include that the fiber serpentine and the serpentine account for more than 90%, with a network structure, the reticular veins are composed of serpentine and powdered magnetite, and serpentine Stone implicit crystal 貭 variant - glue serpentine. 40 samples test results, MgO generally accounts for 38-42%. In addition, it is proved from the survey data of relevant units that there is also ultramafic rock mass near Chongli Beili Village, Jianyang County, and it is verified that the magnetic anomaly of this area is thus formed. The Bureau of Land and Resources Bureau of Fujian Province identified as serpentinite. Pucheng County, grazing watermelon Ping also found pyroxene peridotite, they were small rock-like invasive in the pre-Sinian schist system. The three rock mass just located in the air confirmed
