GEOLOGIC RECONNAISSANCE OF NORTHWESTERN 
PANGASINAN. 
By PauL R. FANNING. 
(From the Division of Mines, Bureau of Science, Manila, P. I.) 
In 1911, northwestern Pangasinan came into a little promi- 
nence through the persistent reports of copper and other metal- 
lic deposits. Oil also was reported by prospectors to exist in vast 
quantities. In March and April a short geologic examination 
was made in order to confirm, if possible, the truth of these state- 
ments and to work out the general structure of the country. The 
latter is shown on a geologic map. The occurrences of copper, 
gold, silver, iron, manganese, and antimony were confirmed, but 
the known deposits appeared to be of no value. Evidence of 
oil or coal was not seen, although the formation is such as to 
permit of the occurrence of either. 
GENERAL GEOGRAPHICAL FEATURES. 
Location—The area examined comprises about 350 square 
kilometers and is located in the northwestern portion of Pan- 
gasinan Province, Luzon, P. I. The region lies between the me- 
ridians 119° 45’ and 120° 10’ east longitude, and the parallels 
15° 55’ and 16° 20’ north latitude, and is bordered on the west 
and north by the China Sea, on the east by Lingayen Gulf, and 
on the south by the Zambales Mountains. Manila lies 180 kilo- 
meters to the south. 
Transportation—The road from Dagupan to Lingayen, the 
capital of the province, is in perfect condition, but from Linga- 
yen to Alaminos the road is passable to wagons during the dry 
months only. There are few roads in the remainder of the 
area, but during the dry season it is not difficult to traverse the 
country on horseback by means of the innumerable native trials. 
These permitted the examination of a large area within a short 
space of time. 
Harbors are found at several places along the coast, partic- 
ularly at Sual where there is deep, well-protected water.
