ABSTRACT


A reconnaissance ground gravity survey was conducted in the Baguio Mineral District (BMD) as a follow-up to the previously conducted magnetic survey over the same area. It served to verify the results obtained from the magnetic survey.

Gravity highs were attributed to the presence of intrusive bodies and igneous rock units. Gravity highs were also found to be associated with metamorphosed rocks. Areas underlain predominantly by sedimentary units registered low gravity values.

A striking result from the gravity investigation of the BMD is the belt of gravity highs, located within the central southern portion of the BMD, that defines an anomalous zone. This anomalous zone coincides with the anomalous zone delineated earlier by the magnetic method. It also agrees with the north- trending prospective zone of mineralization defined by Fernandez and Damasco (1979).
