Petrology of the igneous complex near Lang, California


Dawson, Charles Alexander (1937) Petrology of the igneous complex near Lang, California. Master's thesis, California Institute of Technology.


The region to be considered in this report is in Los Angeles County, Calif. and is included in the Lang Quadrangle surveyed in 1929 with a scale of 1:24,000 and a contour interval of 5 and 25 feet. The region is also shown on the San Fernando Quadrangle with a scale of 1:62,500 and a contour interval of 50 feet. The area mapped is included between two canyons, Pole Canyon immediately south of Lang, and Little Bear Canyon about a mile and three quarters east of Lang.

The area may be reached on the Sierra Highway by turning east into Soledad Canyon just before the Sierra Highway enters Mint Canyon, a distance of about thirty-eight miles from Los Angeles. Lang is about five miles east of the junction of Mint Canyon with Soledad Canyon. The area may be reached by the Southern Pacific Lines which has a siding at Lang.

The problem was undertaken in partial fulfillment of the requirements for the degree of Master of Science at the Calif. Institute of Technology. The work has been done under the direction and guidance of Dr. Ian Campbell, Associate Professor of Petrology at the Calif. Institute.
