磁化率在太和钒钛磁铁矿钻孔岩芯分析中的应用
|
摘要
岩石是由矿物组成的,岩石磁性与一般矿物磁性关系并不大,主要决定于岩石中所含的铁磁性矿物。本文以四川省西昌市太和钒钛磁铁矿13号勘探线ZK1307为基础,应用磁化率数据,并参考其他地质资料,建立了相应的找矿标示。研究认为,当岩石磁化率>20 000×10-5 SI时,可初步判定作为圈定找矿靶区的标志。并建立了相应的回归方程,通过该方程快速预测出岩矿体重的钒钛磁铁矿含量,初步确定找矿靶区矿产品位具有一定的作用。
Rocks are composed of minerals.The relationship between the magnetic properties of rocks and the general mineral magnetism is not much,mainly determined by the ferromagnetic minerals in the rocks.Based on the drilling core ZK1307 of Taihe vanadium titano-magnetite in Xichang,Sichuan,this paper establish a mineral prospecting by using the data of magnetic susceptibility and other geological data.We think,when the number is over 20 000×10-5 SI,it's meaning we have found the vanadium titano-magnetite.And then,We have established a regression equation which can fast prediction of the content of the vanadium titano-magnetite in rock mass,and the equation makes a certain effect.
