A Study Of The Divide-Dewey Contact Of The Boulder Batholith, Francis M. Young
A Study Of The Divide-Dewey Contact Of The Boulder Batholith, Francis M. Young
Bachelors Theses and Reports, 1928 - 1970
The batholith is dated as Paleocene or early Eocene. The rocks of the batholith in this area are classified as ranging from quartz-granodiorite to granodiorite. Variation in mineral content causes a chance in color tone from light to dark gray. swarms of inclusions occur in the igneous rock near the contact.

Basic Information In The Granitic Rocks Of The Boulder Batholith, Clifford G. Sherwin
Bachelors Theses and Reports, 1928 - 1970
Dark fine grained basic masses of rock are found in nearly every part of the Boulder Batholith, these commonly being referred to as inclusions, segregations, autoliths, and various other names. The origin, distribution, and composition of the dark inclusions form the basis for this report.
Attempted Proofs Of The Differentiation Of Magmas By Syntexis, Clifford Wendel
Attempted Proofs Of The Differentiation Of Magmas By Syntexis, Clifford Wendel
Bachelors Theses and Reports, 1928 - 1970
This investigation was an effort to obtain proof of the much disputed principle that most of the observed magnetic differentiations have been due to the assimilation, or syntexis, of the intruded country rocks.
