This historic book may have numerous typos and missing text. Purchasers can download a free scanned copy of the original book (without typos) from the publisher. Not indexed. Not illustrated. 1918 Excerpt: ...one to the ordinary hand specimen, though at a few places, as locally on Diamond Mesa, where this feature was principally noted, they are so closely aggregated as to form half the rock. They are commonly somewhat pinkish and in shape are thickly tabular; their maximum length is 3 inches, but their average length is probably 1 inches. The idiomorphism of the crystals is fairly good, though the faces are rough and uneven, owing to indentation by the other components of the quartz monzonite. In places the orthoclase is obviously perthitic. Inclusions of hornblende, biotite, and titanite are notably abundant and as a rule lie in random orientation throughout the orthoclase. A zonal arrangement of the inclosed minerals is uncommon. The matrix in which the orthoclase phenocrysts are embedded is a coarsely granular assemblage of plagioclase, quartz, orthoclase, biotite, and hornblende, named in descending order of abundance. The plagioclase, as seen under the microscope, dominates strongly over the orthoclase; it is a zoned oligoclase ranging from Ab70An30 on the cores of the crystals to Ab83An17 on the outermost zones. Orthoclase is a very subordinate constituent. Quartz, fairly abundant, lies interstitially between the idiomorphic plagioclase but is subhedral toward the orthoclase. Biotite is present in moderate amount and hornblende in lesser quantity. Magnetite, titanite, apatite, and zircon occur as accessory minerals. Under the microscope the orthoclase phenocrysts are found to be notably microperthitia. In addition to the inclusions of hornblende, biotite, and titanite, which are visible to the unaided eye, they contain plagioclase, quartz (which is partly idiomorphic and itself holds inclusions of titanite and apatite), magnetite, apatite, and zircon...
