Phlogopite rock in Relation to Boron Mineralization: An Exsample from the Houxianyu Boron Deposit
Yang Xiaoming (Liaoning Geological Prospection Institute)
The ore beds of the Houxianyu boron deposit in Liaoning province is widely altered with prominent alteration zonation. According to petrologic analysis of 18 samples of altered rock, phlogopite rock, with regard to its B 2O 3 content, it is generally restricted to the outside of the ore bed, having certain ties with the boron minerlization while no ties are found in altered rock of the same type associated with veins of diorite porphyrite. Taking this regularity as guide to ore hunting has yielded better results in searching for boron occurrences in the study area.
