朱家包包钒钛磁铁矿成因类型为晚期岩浆分异矿床。岩浆岩(矿)体很难找到一个完好流面。本文利用赤平极射投影原理测算流面构造的产状;阐述了这种方法的理论根据,并以实侧介绍具体测算方法及其结果;该方法在不增加任何人力物力的情况下,把由原来难以获得的高条件下取得的数据变成在采场(地质体上)任意可取的原始数性,通过赤平极影换算,获得产状三要素的数据。作者通过三种不同方法测取几十个实际数据与其进行对比分析,最后结论认为,此种方法测算的数据可靠。 The genetic type of the vanadium-titanium magnetite in the Zhujia bag is late magmatic-differentiated deposit. Magmatic rocks (ore) body is difficult to find a perfect surface. In this paper, the origin of the flow surface structure is measured by the principle of the climatic polar projection; the theoretical basis of this method is expounded, and the concrete calculation method and its result are introduced on the real side. Under the condition of not increasing any manpower and material resources, The data originally obtained under difficult conditions are transformed into any desirable original numbers in the stope (geological body), and the data of the three elements of the form are obtained through the conversion of the clipped polar shadow. The author compares dozens of actual data with three different methods and concludes that the data measured by this method is reliable.
