Abstract
The method of multiple regression
analysis was applied to develop a simple
linear functional model on the
chromitite and related mineral resources
in the Zambales Ophiolite Complex (ZOC).
Using the quadrangle geologic maps on
the area as base data, cells of about 6
x 11 km were made on which the variables
were counted or measured. The dependent
variable was set as the number of
occurrences of chromitite or related
deposits per cell and the independent
variables were the fraction of areas
underlain by dunite, peridotite, dike
rocks, pillow basalts and ‘non-ophiolite’
rocks, the lengths of dunite-peridotite
and dunite-gabbro boundaries and the
number of prospects increases with the
area of dunite and length of dunite to
peridotite contact and decreases with
the length of the dunite to gabbro
contact.
