GEOLOGY OF THE PHILIPPINE ISLANDS.

occur in Benguet, as far as we know, as fissure veins in the diorite-andesite 

 and in the sedfmentaries. However, ore deposition may still either be 

 going on in Benguet or else have only recently ceased. rTo connection 

 between the intrasives and the ores is known with certainty, excepting 

 that they both follow (in Benguet) east and west or north and south 

 lines of weakness. 



The "trachytes" referred to are andesites and therefore are to be 

 regarded simply as variations of the andesite-diorite parent magma.
