THE BOREHOLE GEOLOGY
OF MALITBOG-1, TONGONAN, LEYTE, PHILIPPINES

ABSTRACT

 


Cataclastic textures found in the rocks drilled through by Malitbog I, the repetition of sedimentary and volcanic sequences, and the broadening of boundaries between temperature- dependent mineral assemblages, are mainly attributed to a large fault having a displacement of about 500 m, with its locus on the calc-silicate zone.

The complex thermal history of Malitbog is marked by faulting, uplift, and intrusions. Throughout its history, hydrothermal activity was continuous.
